XP locks up when loading AGPCPQ.SYS

fixed my issue

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?

XP reboots during startup

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

works for me

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.

Lardy1664 - Thank you so much!

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!

my laptop locks up when it is loading AGPCPQ.SYS in safe mode command prompt

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

Different causes, different solutions, here is a new one!

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.

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.

AGPCPQ.sys and Dell D800

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/...99-5D75-454F-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.

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!!!!

same problem extra twist

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 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.

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.
