Infinite Loop Fix!

A FIX THAT WORKED FOR ME AND A BUNCH OF OTHER PEOPLE!! READ ON!

Here we go folks, I've been having this problem for almost a year now with my computer (infinite loop and ati2dvag.dll reboot errors), and tried almost everything my mind could possible think of doing. I've tried every solution on this board, and every other board I could find relating to this file and to the infinite loop, with absolutely no success. I tried every driver package available, bios updates, agp chipset updates, every combination of every setting. I've tried reducing power usage in my computer, I've placed more power in my computer... I've added more fans and created an optimal cooling system in my computer. I made sure there were absolutely no IRQ conflicts, and nothing was using the same IRQ as my video card. I've tried with one stick of ram, with one in 1 and 3. I've tried disabling onboard sound, and putting in a soundblaster card. Nothing... I mean nothing, worked at all.

Until now! I found a solution, that has worked for me and a bunch of other people who have tested it for me.
So give it a try, perhaps it will work for you too. My computer has been working 100% since I made this change. There is a chance it could reduce the effeciency of your texture drawing with your video card... but I've tested it with :

Unreal Tournament 2004
Rise Of Nations
Neverwinter Nights
Doom 3
Max Payne 2
Transport Giant
and a bunch of older games....

Anyhow, no more wait, give this a shot :

Right click-mouse over My Computer
Properties
Hardware(Tab)
Device Manager(button)
Click [+] next to System devices
right-mouse on CPU to AGP Controller (or whatever your controller is called, mine was SiS AGP)
Update Driver(button)

Select Install from a list or specific location (Advanced)
Next(button)
Select Don't search. I will choose the driver to install.
Next(button)
Select PCI standard PCI-to-PCI bridge
Next(button)
Finish(button)
Reboot.

Please let me know how this works for you.
Good luck.

I LOVE YOU... Im not sure if it even works, but theres hope...

ill give you an update and im going to spread the word if this works, TY!!! :giddy: :grinthumb

Hmmmmm... didnt work, i have a pci video card, is there anything that I do differently?

I was hoping someone could help with this. Every time i turn on my computer, right before the cursor appears for the 1st time, i get a BSOD saying "ati2dvag.dll caused an infinite loop". It then restarts and works fine. BUT - whenever playing games or watching DVDs or other random tasks, the computer will freeze completely or just randomly reboot. It happens VERY often, but seemingly random. I have no idea what the problem could be... I've tried several things but nothing works.

I tried:
-lowering my AGP to 4x (from 8x)
-re-installing catalyst drivers several times (after completely uninstalling them)
-setting BIOS settings to default settings
-checking heat temperature in the case (all is normal)
-Lowering hardware acceleration in windows
-Turning fastwrite to OFF
-Adjusting screen resolutions

Try installing omega drivers. they may help.

I was battling black screens (needing lengthy reboots with wasted hours
and loss of work) about once a day since installing SP2 and was even
starting to think I should buy a new PC. Your suggestion fixed it
completely.

Thanks a Million!

Hi,

Please bear with me cos I am still learning about all of this stuff and still coming to grips with all these terms.

I have a Radeon 9700 pro. Have many hangs at various stages of boot up and after the desktop has loaded. Only play a few games (Empire Earth, and Total Club Management). Sometimes the system just freezes, sometimes I get a black screen during the boot up, occasionally the blue screen of death, sometimes the screen colours just go all over the place, and sometimes a little white square around the mouse appears and then the pc freezes. But it is always unpredictable as to when it happens and what event caused it.

Anyway things I have tried
* reinstalled the latest radeon drivers. (and deleted the old ones).
*mucked about with the bios and changed the agp aperture a few times.
* tried cobrakaun's fix. (lasted 3 boots).
* have taken it to the computer shop (3 times). They only seem to look for the easy fix and charge a fortune)

So could there be some conflict between the radeon 9700 card and something else?

The motherboard is Epox. (Oh and the PC was specially built by a friend for me but is o/s and unavilable)

Really appreciate anyone's advice. Thank you

Hi! I installed sp2 on a sony vaio laptop with a RADEON 9200 graphic card. After the upgrade, the computer didn't boot anymore, and i got the ati2dvag infinite loop error. I tried everything but nothing worked, until i read your post.
The thing you suggested (PCI to PCI bridge) worked perfectly to me. Thank you very much. :bounce:

I had the same annoying errors regarding infinite loop on ati2dvag.dll. After reading the solution, everything is running smoothly :grinthumb

Thank you for this.

Farking right on, man.

I've been tearing my hair out over this one and had given up on trying to find the perfect way to tweak the seating to give me an illusion of stability. I wound up just shelving the card and putting in a generic I had lying around.

This solution worked like a charm for me. I've had it going for about a week now and haven't had a single infinite loop related issue.

that's just great!!!

too bad I got rid of my looping radeon 8500 over 2 years ago....

I did the pci-to-pci switch because I was having this problem. But now scrolling, etc are extremely slow in firefox. i've uninstalled and reinstalled the radeon driver a couple times now, and it's still the case. am i stuck in pci-to-pci mode? if so, how to go switch back to agp? if not, does anyone know what is causing this extremely slow, jerky scrolling (it's not the hardware acceleration setting because i already had that set to "none" along with disabling write combining).
also, whenever i put hardware exceleration to none, all of the ATI stuff disappears from the display settings tabs and it's just generic--not sure if that matters.
would appreciate any help, thanks!

Thanks big time for that. I've been having problems in general with Visiontek cards on this computer but that got them working. I ended up changing to the PCI to PCI bridge, but then some of the graphic-dependant apps wouldn't work so I checked the settings again. I found VIA CPU to AGP controller after that and switched to it (I have a chaintech board... (based off VIA chipset) and now everything works perfect. Thanks for helping me out :)

I did as was sugested and used the PCI bridge and it fixed my problem of flashing black screens and restart. Unfortunately, now i have another problem:
When i install the catalyst drivers and do the mandatory restart things work absolutely flawlessly. But the second i restart my conmputer and try to run any game/dvd i get checker board distortion on the screen.(alternating squares of correct visualisation and squares of colored lines) I have to completely erase all of the driver by uninstalling and then hunting around with search to find the remainder. once i re-install from clean like that it works just fine untill i restart again. So goes the cycle. Hey at least i dont loop anymore..... If any one could help with this it would be much apreciated.

Like cobrakaun, I was at my wit's end. The problem was that my newly built PC, based on an Asus A8V deluxe revision 2 MOBO and an AMD 64 3200 939 90 nm CPU, ran well only if the room temperature was over 15 C. Colder than that, I got the VPU Recover message. If I disabled VPU, then blue screen which mentioned ati2dvag and an infinite loop. The temperature dependence suggested a hardware problem so I replaced the graphics card (originally ATI, then NVidia and finally back to Radeon 9600 ATI), the MOBO, the PSU, and tried a new HDD and a fresh Windows install. Nothing worked and I was on the point of giving up. Then I tried Windows in Safe Mode and the system now ran well even when cold. This suggested a device and driver loaded when Windows (XP Prof, SP2) ran in full but not safe mode. This brought me to this forum and cobrakaun's post. Did just what he suggested and problem was solved!!! Fantastic relief :) and many thanks to cobrakaun.

But what on earth might explain the temperature dependence? A problem with the VIA chipset on the MOBO or with the CPU? Suggestions welcome though I am not inclined to risk further experimentation for the time being.

Ok Cobrakaun, I've gotta hand it to you. :D No idea how you've come up with that fix, but it sure has worked for me! (So far lasted about 6 reboots with only one momentary black square near mouse cursor that disappeared without locking up the system.) My system isn't very up to date (AMD Athlon 1666 MHz, ASUS a7n266vm MOBO with nVIDIA chipset and a Radeon 7000 graphics accelerator) I think maybe the MOBO just can't handle the graphics acceleration. The fact that it can only handle up to PC 2100 RAM says something about its age.

Anyway, thank you muchly, you've alleviated my frustration with exactly the same probs you and most people on this particular forum have had to endure. Only thing I found after following your instructions was that when going to full screen with some of the Windows Media Player visualizations (especially the "Battery" ones) it's very jerky. Any thoughts? But playing VCDs/DVDs full screen doesn't seem to be a problem.

well i have a 256mb Radeon x300 (PCI-E) that keeps resetting graphics when in games after only short periods, and so i need to know the " equivalent " commands to try fix the loop, which i think is the issue, looping.....i have just bought a 600W psu in case the card drained my old one, but no...same issues again, i just have a quieter and OVERkill power set up now :giddy:

..anywho, i need to know, if anyone knows seen as i dont have pic to agp in my set up!

Omg.. was trying everything and finally a fix that worked! thanks cobrakaun

Cobrakaun:

i've tried your fix, and it seems to work.

The infinite loop usually occured when i opened ATI MMC TV or wanted to configure it while the tv was running. i've never had the loop during gaming.

First let me tell you i've got an image/backup of a XP installation without ANY videocard drivers whatsoever installed. That way i can always fallback to a fully configured installation of XP without having to install windows and all the other software. This also makes sure the only things that changes are the drivers etc i install. I've tried all possible combinations, and concluded that (on my pc) Catalyst 5.3 + MMC 8.03 is the most stable combi.

After i changed the cpu-to-agp controller to the std pci-to-pci coltroller, i installed Catalyst 5.3 and ATI MMC 8.03 (This is a combination of which i'm sure it works). I rebooted everytime after i installed a part of the software of changed something major.

everything worked fine. So far i've followed your directions.

The next thing i did was change the std pci-to-pci controller back to CPU-to-AGP controller.

Until now, all is working flawlessly. I haven't tried gaming yet, but i don't expect any major problems. If they do occur, i'll let you guys know.

Here are some specs of my pc:

P4 3.0GHz, ASUS P4P800-E deluxe
1GB DDR3200
ATI AIW 9800SE 128MB
CATALYST 5.3, ATI MMC 9.03

OK... I came to the same solution BUT, there are things to be very aware of when you do this!!

Exactly what youre doing is removing the AGP motherboard drivers, and switching to a standard generic driver. THIS WILL DISABLE AGP ACCELERATION! your AGP video card can not run at AGP speeds due to the missing driver, and thus, you will experience reduced performance. Its a good fix, and it works like a charm to those of us with the VIA ATI problem, but its only a band-aid. what we should all be doing is harassing VIA into fixing the problem. Until they do, I can garuntee I wont even consider buying a VIA based board again. So stop reading my ranting, and go send them a nasty email ;)

I have a PCI card but had the same problem ever since I got this computer, and nothing fixed it. I tried your fix. I didn't have the system device "CPU to AGP Controller" but I did find "PCI bridge" available as a driver under the system device "LPC controller", so I set it to that.
That didn't help, but there was also a choice of two "82801FB" controllers, one by Intel, which it had previously been set to, and one by Microsoft. I set it to the Microsoft one and I haven't seen a crash or infinite loop since. I've just played four hours straight of Battlefield2 demo and it worked perfectly. Before, it was crashing every 10 mins in that game.

So I think you're definitely on the right track, even for PCI cards. I never would have thought to try that if I hadn't seen your post. Thanks man.

Well, a minute and a hard reset ago, he did it again. Of course, my solution was to good to be true. I think i'll leave it this way. The performance of my system suffered to much from this fix.

One thing, i'd like to note: i've NEVER had it during gaming. Only when i'm watching TV via my AIW and internetting.

Hi, is it possible that by fixing the infinite loop error that myself and all of the above have been experiencing, could have made a mess of my video drivers?

I have since not been able to watch avi or mpeg files since. The sound plays however there are no pictures? How do you go about reversing this fix?

I've tried to do this, but I can't seem to find the right controller for it, it isn't in system devices at all. I have Widows XP and I don't know why it's not there, but does it by any chance run under a different name than those you've given? I really don't want to mess up my computer, but I do want to play the games I have and run the computer without problems.
Help.

Well the love Hate relationship continues....There very few things more frustrating then having a computer problem that there is no clear cut absolute
fix for it.And very few things more satisfying then fixing what you were sure was to be a "Toss the old and get a new" solution.
That said this problem with "ati2dvag bsod" is that kind of problem ,while
cobrakaun's fix worked it did deminish performance (that we paid good money for),and others posted fix's that worked for them but not a blanket fix.
Well heres what worked for me:
First I did "cobrakaun's fix", then I uninstalled the drivers and control panel,restarted went into safe mode used DriverCleaner(download here http://www.drivercleaner.net) then did a file search "ati*.*" and removed all of them,then went into registry use RegCleaner(small free app dowload here http://www.worldstart.com/weekly-download/archives/reg-cleaner4.3.htm) and deleted all entries pertaining to ati there.Restarted in normal mode,stopped windows Hardware installer from running,then stopped all running programs,and installed Cat.ver.5.6,after install did not restart went into SystemInfo/HardWare/DeviceManager/ System Devices,went to what I had changed in "cobrakaun's fix", (which was now PCI bridge standard PCI to PCI Bridge) right clicked that update driver then chose "Via CPU to AGP2.0/AGP3.0 Controller" installed that then started.Durring restart went into
the Bios made sure all Fast writes,reads were disabled and appature size was equal to on card memmory,saved and exit.Once Windows loaded,went into Display/Settings(fixed my resolution)/Advanced/Troubleshooting checked to make sure hardware excel was maxed out,and Write combining was checked,
then went to VPU Recover Tab and checked that it was active left it that way.
5 days no "ati2dvag bsod" ,as I stated above not sure it will work for all but so far is for me(Fingers and toes crossed).

Thank you very much, I'll give it a try as soon as I can and let you know the results ^^.

I had tried different video drivers, plus the cipset drivers for my laptop and with COBRA's advice I was able to boot into VGA mode and make the neccesary pci bridge to pci bridge change, and it fixed the infinite looping! WOOT!

Thank you. I had radeon problems as described with Sony Vaio, this has completely fixed it - I think!

BTW, do you know what the fix is actually doing?

Thanks

Mike

First off, I'd like to thank everyone for the contributions to this thread, these VIA/XP/ATI combo issues can be a pain to troubleshoot. Following Fitz58's modified steps helped resolve the error I was having with a new rig I built for my wife (ASUS A8V Deluxe/ATI RADEON 9800XT 128MB/AMD64 3000+/"WindowsXP SP1 embedded upgraded to SP2" combo). However, I discovered I had to make two changes to his solution to get it to work for this type of system (i'm more used to settings in MSI boards; kinda new to ASUS):


BIOS Settings - In addition to disabling AGP Fast Write for this board, I also had to to disable both AGP 3.0 Calibration cycle & DBI Output for AGP Trans settings and set AGP Mode to 4x instead of 8x. It seemed as if 8x caused instablity for this type of setup once the VIA drivers were re-enabled during the course of Fitz58's steps.


ATI Drivers - Instead of using the Catylyst 5.6 drivers, I went ahead and got the newer ones (as of this post); the 5.9 version. I had to use these since they address a problem my wife was having with Battlefield 2 and City of Heroes.



After modifying the steps as described above, the system is now running solid...although at 4x AGP with no fastwrites; better than nothing :rolleyes: !

help meee!!!

I went and bought myself 2 asus ax300se pciex cards, along with components to build 2 brand new pcs (everything except fot the hdd's).

now, one card works perfectly, while the other repeatedly gets the infinite loop issue. i have tried swapping cards, and i get the same problem with the same card, which leads me to believe that its a card issue with this particular card.

however, when i took the card back to my supplier (eclipse computers in coventry, UK for those interested) and they have "run some tests" and found no fault. twice.

any suggestions please?

anyone??? please?????

Thx. I bought my ATI All-in-Wonder 7000 two years ago and battled with this problem on and off for a year...I finally shelved the card. I cleaned out my basement and found the card...I figured I would google "infinite loop Via Radeon 7000" again and see i anything new showed up...

This fix worked. I only wish i had not given up and seen this post when you posted it in Oct 2004...Oh well.

Hey..my tv card is working now....thanks

the bridge thing didnt work for me my coputer kept restarting, but i found out if you go into your bios and go to your grapichs card setting and disable "spread spectrum" it seems to fix the problem

which is my CPU to AGP controller? i cant wai tot try this fix as i've been having this problem on my toshiba laptop. WindowsXP, ATI radeon 7000 AGP, celeron processor, 256MB RAM.

I am working on a Sony Vaio VGN-S260 and am having that darn infinite loop blue screen then black screen error.

I applied the fix mentioned in the first post and it worked fine temporarily. However, after two weeks of sitting on the shelf I tried to boot it again and to my dismay I got the same frickin' infinite loop error.

Now it was worse than before. I was going to try the bios spectrum fix mentioned by someone but my graphics card does not show up in the bios.

Any other ideas? Fixes? I really need to have this fixed as I can't afford to buy another laptop.

Many thanks!

Some other forum mentioned sth abt disabling "Fast Writes" under the "SMARTGART" tab... I dont hv that option in my Catalyst Control Centre advance interface. Hv disabled the "Write combining" option in Windows Display Properties though, which didnt help either.

Plz help!

...but there was also a choice of two "82801FB" controllers, one by Intel, which it had previously been set to, and one by Microsoft. I set it to the Microsoft one and I haven't seen a crash or infinite loop since...

Hello community !
It's my first post, I thank you all for working that hard together.
I suffer from the same probleme than you, exactly with a X600 PCI express card.
would HugoFirst or anyone else tell me what he'd do with that config :

I haven't read the whole topic yet, I'm on, but maybe that link could be interresting:

bests regards to all of you

....I uninstalled the drivers and control panel,restarted went into safe mode used DriverCleaner(download here http://www.drivercleaner.net) then did a file search "ati*.*" and removed all of them,then went into registry use RegCleaner(small free app dowload here http://www.worldstart.com/weekly-download/archives/reg-cleaner4.3.htm) and deleted all entries pertaining to ati there.Restarted in normal mode,stopped windows Hardware installer from running,then stopped all running programs,and installed Cat.ver.5.6,after install did not restart went into SystemInfo/HardWare/DeviceManager/ System Devices,went to what I had changed in "cobrakaun's fix", (which was now PCI bridge standard PCI to PCI Bridge) right clicked that update driver then chose "Via CPU to AGP2.0/AGP3.0 Controller" installed that then started...

I tried that way too... would someone look up my config and help me please ?
thanks a lot.

Would a cool guy help me please ?
Fitz58 ? HugoFirst ? Does anyone know what he'd do with my problem?
Thanks a lot : I'm getting mad.

A FIX THAT WORKED FOR ME AND A BUNCH OF OTHER PEOPLE!! READ ON!

Here we go folks, I've been having this problem for almost a year now with my computer (infinite loop and ati2dvag.dll reboot errors), and tried almost everything my mind could possible think of doing. I've tried every solution on this board, and every other board I could find relating to this file and to the infinite loop, with absolutely no success. I tried every driver package available, bios updates, agp chipset updates, every combination of every setting. I've tried reducing power usage in my computer, I've placed more power in my computer... I've added more fans and created an optimal cooling system in my computer. I made sure there were absolutely no IRQ conflicts, and nothing was using the same IRQ as my video card. I've tried with one stick of ram, with one in 1 and 3. I've tried disabling onboard sound, and putting in a soundblaster card. Nothing... I mean nothing, worked at all.

Until now! I found a solution, that has worked for me and a bunch of other people who have tested it for me.
So give it a try, perhaps it will work for you too. My computer has been working 100% since I made this change. There is a chance it could reduce the effeciency of your texture drawing with your video card... but I've tested it with :

Unreal Tournament 2004
Rise Of Nations
Neverwinter Nights
Doom 3
Max Payne 2
Transport Giant
and a bunch of older games....

Anyhow, no more wait, give this a shot :

Right click-mouse over My Computer
Properties
Hardware(Tab)
Device Manager(button)
Click [+] next to System devices
right-mouse on CPU to AGP Controller (or whatever your controller is called, mine was SiS AGP)
Update Driver(button)

Select Install from a list or specific location (Advanced)
Next(button)
Select Don't search. I will choose the driver to install.
Next(button)
Select PCI standard PCI-to-PCI bridge
Next(button)
Finish(button)
Reboot.

Please let me know how this works for you.
Good luck.

I can't believe I have been dealing with ATI for over a year trying to fix this and this solution has been here all along. I have had the infinite loop problem for over a year where I would get hard crashes once an hour - sometimes less, depending on the application. This whole time ALI calls this problem and its fix "unknown". They don't know why it happens or how to fix it. Idiots.

Two weeks ago, I finally started to investigate it myself and came across this fix. My graphics card has never run better. Wow. Not a single crash, and everything runs smoothly on NWN, Star Wars BFII, Pirates!, CIv4, and Madden 2005.

I have no idea why this fix works, but it worked liked a DAM for me. Thankyou, thankyou, thankyou. You just saved me a couple hundred bucks I was going to spend on an Nvida card.

A big thank you to cobrakaun for this fix,I searched for a long time for a fix to this problem,this worked for me,don't know why but it does.Many thanks for this fix.My pc now runs smoooooth:grinthumb:D

How do I get to know which is the controller?

The batteries were flat in my wireless keyboard.

Good luck.

man, i have a ati radeon x300 PCI-E, i dont know what to do , i dont know how to apply the solution cobra gave here, please someone help me, im very upset because the pc is brand new!!! please help!

i stuggled with this problem for the last 2 months and finally figured out what was wrong with my vid card. it was my vid card's fan that died, which overheated my system everytime i tried playing any games. i went out and got a new fan for my vid card and everything worked perfectly. so you guys should test your vid card fan to see if its runing correctly. besides that, i dont know. good luck

Thank you, dude! :)

About less than 20 hours ago, I woke up to find that my pc had hung with some corrupted display(a line of coloured bars at the top of the screen). Then, it could not boot up anymore and kept having some beeping sounds. After leaving the pc off for about a few hours or so, I managed to get the pc boot up again. And it lasted for a few hours until it froze again.

So, I hope this fix(PCI to PCI) might help counteract the problem on the software side, while I figure out what else might be causing this issue, hardware-wise.
