XP locks up when loading AGPCPQ.SYS

I have reinstalled xp pro at least 5 times and my IBM 8315-kau lock every time it start to boot, I can't boot to safe mode. It loads drivers until AGPCPQ.SYS and go to black screen and starts to reboot again. I only have a recovery disk from Ibm. I have read that it is the sp2 pac. But I don't know how to get past it.
Some things say to install a new video card, but will that fix the problem. I believe this is a driver problem. but not sure. Thanks

I've seen it on multiple IBM S50 desktops - when booting into safe mode the process halts while trying to load this file - apgcpq.sys. This file is the cpu to agp controller driver. I have not found a solution yet but am still digging. Has anyone else out there seen this?

I am running Windows XP SP1.

We're experiencing the same problem with images created for the Dell Latitude 610 & 400. We have tried both SP1 and SP2 with the same results. I'll report back here if I find anything that leads to an answer.

An upgrade to the latest BIOS seemed to do justice for the S50 desktop I have here. However, one of my customer's wanted XP Pro on a Dell PowerEdge 400SC server, and the problem remains, latest BIOS and all.

I just recieved my xp SP2 and I can't install it. I can't get to safe mode, command promt, All it will do is just boot to the agpcpq.sys and black screen and start over. This is one of the hardest problems I had. Reinstalling xp does nothing to help.

There's a similar problem out there with agp440.sys that Microsoft has an article for: http://support.microsoft.com/default.aspx?scid=kb;en-us;324764

I got in touch with IBM and they told me to update the bios. and gave me the update for my IBM 8315-kau. After the bios update it works great. So If you are having the same agpcpq.sys problem update your bios.

I've had the same problem on several Dell GX270's. I updated the bios. No change. Ran a HDD recovery tool and the HD had tons of bad sectors. This machine had just been updated with SP2. I still don't have a fix, but I was curious if anyone else had checked HD integrity and what the results were.

Have IBM Netvista 8307-47U. Worked fine until a power failure happened during a reboot. PC is connected to UPS. Infinite reboot cycle since then. Updated to current BIOS - no change. If HDD is installed as slave, I can see and access the data. Ghost will not boot to diskette - pc locks. I believe it is related to the Master Boot Record, Partition Table. :confused:

gateway 614ge - same problem... anyone ever figure out a workaround? i tried a pci vidcard... i WAS however, able to install a working xp in a new folder titled windows2 on c:

can't access the old documents folder though :( access denied...

Hi
Just joined this forum after finding some useful items about the xp boot problem appearing to stop at the agpcpq.sys file load.

I have been looking at a friends advent 3312 that developed the fault of locking up on the windows screen but it would still load up into safe mode.
When I ran the logged OPTION / DEBUG I found that it appeares that the agpcpq.sys is the last driver to load before the freeze . However I noticed that the next driver in the list was the acpi control file.

I looked onto the microsoft site acpi faults (http://support.microsoft.com/kb/216573/en-us) and found that this power management makes an assumption on the state of the systems bios.
As I can not find a bios update for my advent 3312 ( not supported by MSI )
I decided to change the settings in the Txtsetup.sif to either force acpi on or force it off.
I found that by forcing it off ,( change properties of file to not read only and edit value in notepad , save file and set back to read only ) setting the value of the "ACPIEnable" string to 0 just under [ACPIOptions] the pc has booted up for the first time in 3 days and all looks ok .

All I can assume is that the bios has been corrupted following a power supply fail that first started the problem .

I've looked to see if this will have any detrement to the system but not found anything so far

Hope this helps any others out there , might be especially good with notebooks

Hi,
I have a Dell 8400 with XP.
I have had this fault occur two or three times in the last year - either after removal of software or a crash (rare).
I could find no solution on the net, and too found that in safe mode the boot up stopped at agpcpq.sys.
But actually, the boot does not stop on my computer.
If you have this fault. Try booting up in normal mode.
It will take you past the windows boot up screen and take you to a black screen.
Nothing happens, no disk activity. It appears locked.
I have found - always that after about five minutes, yes, five minutes, the boot up proceeds and completes perfectly.
This will happen one, two or three times on successive occasions.
But usually - it seems to be the following day, the computer boots up normally and quickly and the fault does not re-occur - until another crash maybe.
Of course I do not understand what is happening. It is as if the boot up process fails to find something (e.g. like the monitor) and then does, and then remembers where it is. I am sure this is simplistic

I'm playing with the VMware server (a virtual machine) and decided to drop an XP Pro image on it. So far I've not been able to get the image to work and the symptoms seem to be identical to what everyone here is reporting. During a safe boot the last line that shows before the crash is Multi(0)disk(0)rdisk(0)partition(1)\WINDOWS\System32\DRIVERS\agpCPQ.sys.

For a very breif moment before the reboot it will show the following info:

This info so far is worthless to me. It's a virtual machine and I downloaded the latest version of VMware server just this weekend. The BIOS, hard drives, video card, etc... are all virtual and not real hardware.

I'm inclined to say that it is a video issue of some type. The XP Pro Image I'm using has been syspreped and once I drop this image on a real physical PC I can not change the video mode the first time it boots up and the video will be at a lower res (probably 640x480). If I try to go straight in on the first boot and change the video mode the system will instantly crash/reboot. But if I allow it to boot up all the way, and then restart the PC, then on the second or later boot ups the video mode will be at a little larger res (I believe 800x600) and I can change the video mode without problems. I think XP on this image is improperly identifying the video on the first boot but does properly identify the video on the second boot. This is just fine as long as the computer makes one full successful boot. In the VMware case the failure to properly identify the video card may be causing the crash and preventing a full successful boot up. The system starts over and tries the same thing over and over again.

Just theory and for the most part I’m clueless the cause. If I get a real solution I’ll post it.

FYI: Just tried the same image in VMWare server with SCSI instead of IDE and the image still crashes at the agpCPQ.sys line.

OK folks i have tried all the great stuff to get this to go away. and its not working. updated bios, format mbr, wiped hard drive, installed new os xp pro sp1 and sp2 oem cd's and burnt copy, tried ghost image. tried reloading fresh drive out of the sp2.cab file. loaded up with bart pe and look at the file but its not in system32/drivers anymore its in two diffrent spots windows/drivercache/i386/sp2.cab and windows/i386/sp2.cab but you are not able to extract it to the correct destination because it want to put out the entire cab file i did that. dont do that not fun to fix. also run memtest x86

here is a list of other files that the file is assoceated with as well,
drvindex,
layout,
machine in 6 instances windows/inf,
windows/system32/reinstallbackups/oo1.002.004.009.0010/driverfiles

if you dont have a live file system on dvd or cd i would suggest two of them. Knoppix it a live linux file system, and bart pe wich is a windows based live file system. it helps when trying to reload the file in question. if anyone has something else to try

I have had my first experience of an infinite re-boot which seems associated to this agpCPQ.sys related (or relevant) problem. A customer's Acer Aspire WLMi is now back to a clean booting state after some considerable and I have to say experimental efforts. I firstly tried the Bios upgrade recommendations and followed various routes to do with other agp***.sys forums to no avail. I believe this laptop's problem stems from a crash during heavy 'game-play' in a graphic intensive app so I thoroughly inspected the ../../sys~32/drivers file using knoppix 4 on CD I could find no signs of obvious error or corruption, I copied a few files over from a healthy XPhome system in Dos mode (agpCPQ.. hal.dll) no change resulted. Next I tried a thorough work-through with Partition Magic again in Dos.. which failed to read the C drive spouting a non-specific read-error then a little 'simple thinking' struck me. No scandisk.exe was present in the C drive so I copied one in again in dos; a run revealed a fat error which it promptly fixed as well as several file errors in i386... this resulted in a normal(ish) boot up then some careful scanning and probing revealed some still resident errors which were fixed on the next re-boot. I now have some residual minor errors which are not greatly affecting system stability and performance, but there is a possible clue as to the origin of this particular problem... the ACPI mangement seems to be disabled or corrupted.. I will keep you all posted as to my findings, and the best of luck.. I hope this helps.

.... The residual problem in XP after the fix I posted was 'Power management' being somewhat cobbled... several missing tabs in control panel/power options; leaving the laptop with no proper battery notification and power management features being mostly invisible and therefore near impossible to change. I believe this was caused by replacing the HAL.DLL in my 'fix' post above which was possibly part of the origin of the problem.
The answer was simple... In device manager- update driver of computer/ACPI-uniprocessor, select ".. from a list..." and from the list of available hardware choose another version of ACPI computer; I chose 'Advanced configuration and Power Interface (ACPI) PC'... this simply replaces the ACPI files and asks for a reboot. On start-up the power management features were found to be completely restored and all in working order. This absolutely non-booting, no recovery disc Acer laptop is now returning to it's owner fully fixed. I still have only patchy evidence of what causes this problem in the first place... some clues have shown up in the now working system ... Windows Update may be to blame!
I will keep delving and post my findings soon. Hope this all helps.

Hi Techman,
I think you are right. It didn't occur to me at the time when I spent hours fixing this on the client's laptop; but yes, it was formatted Fat32. I did go on to run the convert afterwards and all has remained well; so I hope it helps as many as possible to get out of watching the fastest blue screen in the west!!

To all who land here in desperation... take your time, be patient... and the answer will always come.

it worked for me (with a gateway 7322):

Plan A


1. remove the battery
2. unplug your pc
3. connect the power
4. turn on your pc
5. on the gateway boot screen, press F2 or whatever it is to enter bios setup
6. get to the following screen and disable "Intel SpeedStep"
7. Exit WITH changes.
8. Are you sure you saved the changed (Intel SpeedStep disabled)?
9. As soon as you save the config, your computer will start again, you shoudl see the windows screen, and if it doesnt start normally, give it 5 minutes. if nothing proceed to plan B


Plan B


1. remove the battery
2. unplug your pc
3. connect the power
4. turn on your pc
5. on the gateway boot screen, press F2 or whatever it is to enter bios setup
6. get to the following screen and disable EVERYTHING on the Advanced Tab. (check out the img below)
7. Exit WITH changes.
8. Are you sure you saved the changes (the advanced tab just like the img below)
9. As soon as you save the config, your computer will start again, you shoudl see the windows screen, and if it doesnt start normally, give it 5 minutes. if nothing proceed to plan C.


PLAN C.


1. start the computer.
2. on the second screen, after the gateway logo, press F11, or whatever key it is to enter gateway recovery partition.
3. choose DESTRUCTIVE option (if you want to try backup mode, its up to you, but dont blame me if it doesnt work, try it anyway, doesnt do any harm)
4. follow all the instructions for recovery.
5. after like 1 reboot, the windows setup will detect all the hardware. you will notice the blue progress bar freezes at about half way. if it does, its ok, just disconnect the power.
6. start the computer and enter bios setup.
7. disable EVERYTHING in advanced, just like you did onplan B.
[primary]
[disabled]
[disabled]
[disabled]
[disabled]
[disabled]
[off]
[max]


8. save and exit with changes.
9. let the computer run. now it should go throughj the hardware detection screen. if it doesnt, run again gateway recovery. just make sure you got everythong disabled in advanced before you recover again, this time, it shouldn't freeze.


That's it!!!


now after you setup windows and get it running smooth, you may re-enable EVERYTHING you disabled in the advanced tab in the bios setup. there is an option to restore all the defaults for the bios, i recommend that. if the problem rises again, try to disable everything again ad work your way up until you find whats causing it.


if it doesn't work, hey, its not my fault, but it worked for me!!

the folllwing screenshots are from my bios setup. if you have a gateway 7322 it should look like this:

I killed the power during another attempted normal windows xp media center failed boot, this intern forced windows into a chkdsk, this intern sorted me right out! Hope this can help some one - if it does let me know eh?

tweekyd and techman, my gateway 507gr has recently started doing this & I tried following your steps. In order to get to a c prompt I used a win98 boot disk, which of course does not have te convert command. My question is how do I know if my windows xp was installed in fat32 or ntfs? Since my xp is OEM I do not have a bootup disk for xp. Is there an easy way to make/get one just to get to the c prompt?

Thanks for sharing!

i have a generic gateway laptop (Pentium 4, running XP SP2) i recieved through my school which has been having this problem off and on for almost a year now. thankfully, i've finally been able to resolve the problem (again, and hopefully this time for good) by following a variation of # 2 on Solidox's list.

I say variation as my advanced options only had 2 of the fields his did, "USB Legacy Support" and "Hyperthreading" (and AutoDim if you want to get picky). After resetting BIOS to defaults and disabling these two fields I was able to get my comp to enter Recovery options for the first time in over 2 months! After doing a non-destructive restore and some trial and error I found out 'USB Legacy Support' was the guilty culprit, though I don't know enough about computers or what USB Legacy Support is to tell you why.

Hope this helps someone, and thanks to Solidox, and everyon else on this thread, it's been a light in the dark so to speak.

Techman,

Sorry problem is not gone.

Happens to me on NTFS all the time
tried 2 different new Maxtor 200GB HDs on NTFS

Have AMD Dual Core Athlon 4400+ on Win2k SP2
2GB DRAM, 200 GB HD on A8N-SLI-Deluxe
Motherboard running on parallel IDE with all SATA disabled

Latest ASUS bios vs 1016 and tried even later beta version
Hangs on agpcpq.sys and won't boot in any mode

Give BSOD 7E stop error with no driver or other comments,if you are lucky enough to ocassionally get there, then sometimes 7B error and corrupts NTOSkrnl.

Running chkdsk fixes it and then happens again

Tried most bios settings, and PCI rather than PCI-E graphics card and various IDE driver controller software (Nvdia and Microsoft) and smaller DRAM memory (512MB)

Saw a Microsoft note that changing from Intel CPU to AMD on Win 2K can cause grief in sysprep because of registry esoterics left behind and is not supported.

My XP HD used in AMD dual core is a clone of a 2.8GHZ Intel Pentium 4 Win XP sp2 that runs AOK

All clones used Acronis not sysprep

Interesting problem because I tried putting in a cloned WIN 2K SP4 on same AMD dual core machine and it runs AOK on exactly the same hardware with no boot issues

Noticed VMware post on this board so it may be an XP cloning issue
or another new Intel/AMD changeover issue, and I plan to try a fresh Win XP SP2 install

It seems everyone is having this problem after a crash or shutdown. For me I took the cmos battery out to check the volts. This of course resets the bios settings. My fix for a GX150 was to re-enable the IOAPIC support in 'integrated devices'
Thanks for all the clues.

Thank you for your message Lardy1664!

I replaced a motherboard in a PC, but turned off the power management as I always do. The recovery media required that it be turn on.

Thanks to your message, I turned power management back on, and voila!

Thanks again.

Visiting my folk’s house, I found their computer had been down for 8 days. It was the same story as everyone else here has already told.

in ntbtlog.txt:
<long series of "Loaded driver XXX">
Loaded driver agpCPQ.sys
Did not load driver ACPI Multiprocessor PC
<more “Did not load driver YYY">

After, messing around with various settings in msconfig.exe, I went to the BIOS. Long story short, it finally worked when I went into BIOS and disabled hyperthreading. Of course, while in BIOS, I was only changing one setting at a time (change one setting, test, change it back, pick another setting, repeat ad nauseum.)

my latest entries in ntbtlog:
<long series of "Loaded driver XXX">
Loaded driver agpCPQ.sys
Loaded driver \SystemRoot\system32\DRIVERS\intelppm.sys
<more of the same>

So I don’t know if or why hyperthreading was the problem, but this simple solution worked for me. I am just really really glad I didn’t have to format the hard drive and/or reinstall XP, so I decided to share. So, 9 hours later I can say Thanks for all your help!

I got a new laptop not too long ago, and lately, it won't start up. At first, I thought it was a virus, but now, when I start safe mode command prompt, it's stuck at AGPCPQ.SYS. I don't know a thing about laptop issues, and I hope it will be fixed soon from the manufacturer.

Best to do a reformat and reinstall, then if you have the same problem, get it back to the manufacturer under warranty.

hi, a workmate gave me his laptop to look at for him which was also stalling at agpCPQ.sys
to fix it i booted from the windows disk and went into recovery console and ran chkdsk. it booted up perfectly after that.

cheers mick

Okay I have something for those with Windows XP w/SP2, who cannot boot to 'Safe Mode'.

If you can change your boot.ini, then this will work... Easy as pie:

I too was getting agpcpq and/or Wup(??) lock-up at boot (only when going to 'Safe Mode'. Otherwise it booted fine.) The following options added to the end of the "multi(0)disk(0)rdisk(0)partition(1)..." enabled me to get into Windows XP 'Safe Mode' and replace a dll which was normally loaded upon boot. After you have made your changes in safe mode, just open msconfig to change the boot.ini back to 'normal' settings.

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /safeboot:minimal

Those of you who have image copied from one machine to another (either physical or virtual) have a good chance of running into both HAL and video driver problems. For VMware and Virtual PC users, this is a common problem when doing a Physical To Virtual (P2V) conversion.

Here is a series of four links that conclude with a description of how to replace the HAL. This technique applies to moving from any machine to any machine regardless of whether the machines are physical or virtual. The overall series was written for those doing P2V, but general principles apply.
http://blogs.msdn.com/virtual_pc_guy/archive/2004/11/22/268225.aspx
http://blogs.msdn.com/virtual_pc_guy/archive/2004/11/30/272662.aspx
http://blogs.msdn.com/virtual_pc_guy/archive/2004/12/10/279667.aspx
http://blogs.msdn.com/virtual_pc_guy/archive/2004/12/16/316643.aspx

Even after replacing the HAL, video driver problems can prevent you from fully booting into your machine and using it. If you edit the boot.ini file and add /basevideo to force VGA mode and ignore the existing video driver, you will probably succeed.

Add a line like this to your boot.ini

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Professional VGA mode" /noexecute=optin /fastdetect /basevideo

How do you do that on a system that won't boot? Using the Recovery console is one way. Another is to attach the disk to a functioning machine and use the functioning OS to edit the boot.ini file. This even works on a virtual machine. Add your virtual machine file to a working vm and use the working vm to edit the file. Then boot the broken vm and select the option to boot into VGA mode using the /basevideo switch.

Hello,


My situation is a little different. I am receiving this error when trying to create a universal Ghost image created on an Intel DUO, and installing it on a Intel Centrino laptop. I have tried everything in this post to no avail. I did find the below link which pushed me in the right direction.

http://www.microsoft.com/downloads/details.aspx?amp;displaylang=en&familyid=9B99C199-5D75-454F-AE07-B620727BE8D8&displaylang=en

It did not solve my problem but the info was useful, and I am pushing this patch on my installation point just in case.

After much reading I am pretty sure it has to do with the Microcode Update and the Update.sys file, which is also having issues with XP SP2.

Resolution was to create the image on a Intel P4 laptop (could use workstation) which worked on both the older Centrino and the new DUO processors.

Funny how the image created on the DUO would work on a AMD X2 but not a older Intel chip.

Ok guys i am brand new to this forum and I have the same problem all of you have, however I did get the PC to finally boot in safe mode.

After I rand during chdisk it fixed a lot of corupt files then it locked up saying there wasnt enough memory. So I rebooted then I got a Partmgr.sys error. I restarted again and went into safe mode and after about 30 min I am in windows (in safe mode) I am however afraid to restart is there anything I can do while in safe mode to stop this problem.

Machine Dell Inspiron 8600 NSTF XP Pro

Thanks

I managed to solve the agpCPQ rebooting problem by following this link
http://support.microsoft.com/?kbid=310396, My PC is now all better. Happy days!!!!

all this has been really helpful but i've got a friend who has an extra twist to their tale

their using a phillips freevents (think it's an x50 or 51) and a little while ago the cd drive doesn't appear in the my computer disply (no biggie here as i know that's just a matter of changing some settings in regedit) but as this agpcpq.sys problem also occured and the cd drive isn't appearing i can't boot from cd-rom to get into command prompt and change the partition to ntfs, unfortunately she only brought her pc round after both problems occurred.

does anyone know of a workaround that i could use to force her laptop to boot? or is there another way of solving this problem?

Both Phillips Freevents X50 and X51... Have early failure rate on the optical drives... but they should be good for the first year.
What is the build date on the bottom of the laptop.
When the optical drive dies, its main symptom is that it can no longer be detected. But first, try to get around that issue. There is no way to test for it until you try a few other options.
Remove the CD drive. It has a special clip. Shut down. Restart.

If it boots up, I would update the BIOS to assure it is the latest, then download an install the chipset.
Usually the updated BIOS will fix all related problems, if all your SP2 files are up to date, and all the Microsoft updates are installed.
Then reinstall the optical drive.
There were some good microsoft knowledgebase articles on this error, last time I checked. There are some helpful clues there..

hi, a workmate gave me his laptop to look at for him which was also stalling at agpCPQ.sys
to fix it i booted from the windows disk and went into recovery console and ran chkdsk. it booted up perfectly after that.

Hi all!

I found that my Thinkpad had this exact problem this morning, the boot process halted when loading the agpCPQ.sys file, so I did exactly has mick2 did, i went into the recovery console and ran CHKDSK with the /r option to repair problems and after that it worked again.

....
The answer was simple... In device manager- update driver of computer/ACPI-uniprocessor, select ".. from a list..." and from the list of available hardware choose another version of ACPI computer; I chose 'Advanced configuration and Power Interface (ACPI) PC'... this simply replaces the ACPI files and asks for a reboot. On start-up the power management features were found to be completely restored and all in working order. This absolutely non-booting, no recovery disc Acer laptop is now returning to it's owner fully fixed.

I have an ACER lappy 5633 Windows XP Media Center and tried the above as I couldn't get into SAFE mode (boot halted at the agpcpq.sys file) but I could get into Windows normally.

Now, after doing the above, I can't get into windows at all - there's BSOD, which can only be read if I disable reboot on error and I'm stuck in a loop with the machine rebooting and failing constantly. And to add to my woes I don't have a Windows XP CD just a recovery one and I don't want to go back to factory settings *groan*.

So my advice is DONT DO IT! :(

PS if anyone has any advice on how to somehow revert the ACPI setting back to what it was I would much appreciate it.

This fix is VERY model, mainboard, and hard drive specific. You are taking great risks on several different models of the same manufacturer of ACER, ASUS, Gateway, Lenovo Thinkpad, and Alienware... perhaps several others... If your drive is larger than 80 GB (and with certain BIOS installs), you might be at risk...so do your research.

The post by TWEEKYD with the fix in didn't imply that it was anything other than simple. No posts since then have intimated that it should be done with caution either - or that it should not be done on similar ACER models.

That's why I felt compelled to register and post - in the hope I can stop someone else following that advice and ending up in the same mess as I am now in.

:(

We agree that you did the right thing. It is not simple, and on certain systems it is indeed very risky... as you have learned. In our experience, the problems seem to revolve around very large mobile 2.5" drives 80 GB and over from Seagate and Hitachi, when combined with certain runs of motherboards.
There are only 7 laptop manufacturers in the world nowadays... but they are sold under 87 different brand names. This makes it very difficult for users to get accurate information.
Strangely, the problems only occur on certain models. For instance, IBM Thinkpads, which are superb, will have the errors on some and not others.
The Gateway problems are also spotty. Alienware problems, Acer, and ASUS units seem to be more severe across more models.

I'm having the same problem with a friends Gateway MX 6930....endless reboots. Disabled automatic restart to read the BSOD and got stop error
0x24. Cant even get to a C: prompt to run checkdisk.
Will not start Normally, Safe Mode w/Comand prompt, Safe Mode w/network, last known good configuration..etc. In safe mode it hangs at AGPCPQ.SYS and then reboots.
Used the recovery disc and nothing happened. Used the Operating System Disc to try to get to the recovery console , selected "R", begins recovery and hangs at "please wait". I left it for a few hours and all it did was start the rebooting process all over again.
I trieid putting a WinXP disc in from another computer to try and repair from that and had no success. The hard drive is recognized in the BIOS.
I tried the other applicable suggestions above and had no success with them.
I'm suspecting a bad hard drive sector (boot?)
Any ideas or other suggestions would be greatly appreciated

my windows does not start. i found about 20 minites before it loads. I ran the safe mode and it halts at agpcpq. tried reloading all software from factory settings still no improvement.

However, when i start in safe mode and the get out of the mode and restart the computer, windows starts properly. The moment i power down (not restart) and start in normal mode, windows halts and does not start for about 20 minutes. Going to safe mode and then restarting is the only thing I can do.

Any body, please help

The moment i power down (not restart) and start in normal mode, windows halts and does not start for about 20 minutes. Going to safe mode and then restarting is the only thing I can do.

Any body, please help

I had a Gateway desktop winodws xp with sp2. Some windows automatic update ran on March10, 2008 and when the computer rebooted it would get about 10 seconds into the windows startup and reboot. Safemode would hang on the agpcpq.sys file and then reboot. I used an XP install cd to bootand chose the R option to get to a command prompt. I could change to C: but when I typed DIR it said the directory couldn't be shown. So I type chckdsk /r from the C: prompt and it ran for about 3 hours, fixed one error and rebooted and was back up and running again with one error at the login about a windows restore file being corrupted and to run chkdsk. I'm going to make a complete Ghost backup before I do anything at this point then maybe run chkdsk again.

Try setting your SATA operation to 'ATA' in the BIOS.

I had all the same problems with my Dell Precision 390 after cloning the original disk. I tried everything listed in this thread to no avail.

I finally fixed it by changing the BIOS setting, SATA Operation from AHCI to ATI

Now works a treat.

Hi guys I've been following this problem since yesterday. I've read all the posts and I think I have something worth while to add here.

I have been given a computer by a friend at work to fix and I have been encountering the same problem (XP locks up after loading AGPCPQ.SYS).

Initially the system would not load windows. It went through to the windows loading screen only briefly before entering an infinte reboot cycle. The first thing I did was load the recovery console and run chkdsk. Having read the forum and seeing all the trouble everyone has been having I was amazed to find that the machine started normally after chkdsk reported some errors and repaired them. I restarted several times and everything seemed to be working but the machine was very slow. I decided to install some anti virus and spyware removal tools and did some scans and they turned up minimal results. By then it was late so I shut the machine down and I went to bed.

However, that was last night and today I turned on the machine only to be greated with a slightly different problem. The machine began to start normally and went through to the windows loading screen but this time after about 10 or or 20 seconds the screen went blank and my monitor showed it was receiving no signal from the computer. The machine itself was still on and showing the HDD light however. After a couple of minutes the machine restarts on its own and takes me to the boot options prompt.

I decided to run chkdsk again from the recovery console and it returned the message that it found errors that were unrecoverable. Much to my distaste. So I decided to use the commands FIXBOOT and FIXMBR (master boot record) and see if that might aid me. When I ran FIXMBR I recieved the warning "*caution* it appears the master boot record is invalid or non-standard...etc" I decided to continue with the process.

I tried safe mode with command prompt and that worked so I decided to try full safe mode. When it restarted this time it decided that it was going to run the disk scan before it started windows so I let it carry on with it. To my horror it began returning "File record segment XXXX is unreadable" errors. Litterally hundreds of them.

It's still scanning now and I decided to do some resarch on what causes this error while I wait and it appears that it could very well be that the HDD has had it's chips. DskChk showed that the machine is only 4 years old (Disk partition created 2004) which surprised me. I don't know the full spec of the system as I can't get in to windows to look. All I know is that it is a Pacard Bell approximately 4 years old and uses an NTFS file system.

Hopefully when/if it completes the scan I will be able to get into windows and back up my friends files. If even in safe mode at least but I am seriously beginning to think that the machine is on its last legs. If all else fails I have another system in which I can install the HDD and take the files that way, using my friends HDD as a slave.

I am begining to think that not everyone here has been experiancing exactly the same problem. Especially since there are those who could not get their system to boot even after installing a fresh copy of windows and then there are also some who can use the CD to use the recovery console, enter safe mode or start windows normally. In this case it means that anyone else encountering this problem may find that some of the fixes posted here are not going to help you at all and could actually be counter productive. I would strongly suggest that before you try the most simple, least intrusive fixes like chkdsk in the recovery tool before you attempt anything serious like a reinstall or a repair.
