PC crashing while playing games. Could be a driver error but unsure!

For quite awhile now my pc has been shutting itself down completely when playing games. It can be a really old game like Diablo II or a new demanding game like Crysis. I thought it had to do with my graphicscard getting to warm but BFG assured me that my 8800gts should be able to handle temps over 80c and the card never became warmer than 78c in games.

Last night I crashed in any game after playing for just 5 minutes. So this morning I decided to test out what could be wrong. I ran memtest86+ and made through 3 passes without errors before I decided that it couldn't be the RAM.

I ran RTHDRIBL for two hours in fullscreen and my graphics card was on 78c during the entire time but the pc never crashed.

I then ran Prime95 and tested my q6600 for a few hours without any errors. I tried stressing two cores at once leaving the others two unstressed and then i stressed all four at the same time without errors.

I googled alittle and found this thread here on toms hardware http://www.tomshardware.co.uk/forum/237556-34-nvidia-driver-crashing-issue-8800gt

It seemed sort of like the problem I was having.

I was planning on opening my chassi and checking that everything looks fine and that all the cables are wired before I uninstall this driver.

I just wanted to post this here and ask you if you think it could be the nvidia 177.83 driver that has been crashing my system?

My speccs:

Windows vista x64 ultimate
q6600 (not overclocked)
4GB RAM
BFG Geforce 8800gts 512mb factory OC
Asus P5K Premium MoBo
Corsair PowerSupply 620W HX ATX

None of the parts are older than six months. Again im just wondering if you think it could be the drivers causing this (didnt know a driver could cause a full system crash like that) and how I should go about uninstalling the drivers to really make sure nothing is left that could make me crash again.

Sorry for the textwall and thanks in advance for any help!
 
Try getting another PSU if you have a close person that can lend you one. I think when you try to get the juice from it, it can't handle the load. Could be defective, that's my point :p

And since you already did the stress tests, i can't think of another thingy, 'cept for Vista being culprint, lol.

Esop!

EDIT: Added thingy.

Ah that could be it. I just checked inside the chassi and dusted it out abit.. everything seemed fine so I booted up again, started crysis warhead and less than a minute in-game the pc shut off.

But doesn't the PSU need to provide the juice when I do those tests on my graphicscard or is it different from when actually running a game?

In any case I think your right but other suggesstions are welcome until I figure this out.
 
I don't think it is the PSU, as the problem is limited to games, not other things that are at least as demanding for juice.
Check your sound drivers also. If you turn off sound in any of these games, does it still crash?
 
Well when running memtest or prime95, your video card isn't being stressed. When your video card is under load it uses more power. That power supply should be more than enough to handle it, but if you got a slightly defective unit then it would crap out under load. Before you go swapping PSUs though uninstall your drivers and try a different version. Could be a driver somewhere just isn't playing nice. Really a video card driver failure is not suppose to cause a system crash under Vista, but it still happens :p .

well,,,i tried those 177.83 drivers with XP and had similar results,did not qiute crash,but, did not run that well either,,got rid of them..Yeeeuuuck!!
try and get your hands on Your Uninstaller any version from 2006 up it is way better than the sick add remove crap it actually gets the leftover crap that is left behind to infest your registry and it also has an auto fix for cleaning up bad uninstalls,dunno how i got along without it,,really..and 620w should be more that sufficent,hell i'm only running 600w with my 8800gt, +2g ram ,+amd 5000+ BE,,,had the same psu on a q6600 slacr no problems at all:)

Thanks for the replies guys. I tried the latest nvidia driver that was available from nvidia.com and I got the same crash after just a few seconds in-game.

Tomorrow ill try checking if the sound is the thing causing it and ill also try and stress my gpu with 3D Mark as suggested :) Thanks!

I don't think its the sound drivers thats causing it. Im still stumped to what's causing this.

After I posted my last message last night the pc has been shut off for about 10 hours. I started it about an hour ago and ran crysis warhead just fine without crashing once (everything except shadows on enthusiast highest setting).

So now it all seems fine and now when I think about it the crashes usually happen later in the day when the pc has been on for quite awhile and I can seem to run any program for hours no matter the strain it puts on the cpu and graphics card.

I also tried stressing the pc with 3DMark Vantage and that ran fine aswell (I did 2 runs).

Here is the temperatures after about an hour in crysis warhead: printscreen of temps

They don't look that bad. So can it really be the PSU that's the problem? It seems to send enough juice under load fine now atleast.

Im clueless as to what can be wrong yet again :/ Any ideas?
 
Hmmm, that points back to heat, possibly of something not clearly measured. How is the chipset? After one crash, take the side of your case off and blow a common fan into your PC, then see if it crashes again.
Does your case have good airflow, with intake and exhaust fairly well balanced? Remember the PSU is an exhaust.

I don't have any fan to try that with :/

My case has small airholes everywhere to not make the heat stay inside the case. There is more exhaust than intake though.

Anyways the pc has been on all day today and not one crash so far :/

Will try and stress it some more with 3Dmark and just fiddle around and see if I find anything. Thanks for the support guys!
 
A little more exhaust than intake is good, but too much more and the PSU will be struggling to pull air through itself for cooling. Make sure you have at least one good intake, preferably in the front.

Yeah I got one good intake in the front.

Anyhow. About two hours ago I ran an hour long stress test on the pc. I ran four instances of prime95 stressing each of my four cpu cores to the max and at the same time I ran rthdribl and stressed the graphics card aswell. I ran the rthdribl in fullscreen mode with some really demanding settings. It ran completely fine the whole hour without errors or crashes. I then let my computer rest for about an hour while I had dinner. When I got back I started up crysis warhead and played fine for about five minutes before the pc shut itself off :/

It seems so damn weird that it just crashes under heavy game load and nothing else. So that brings me back to thinking its not a heat issue or am I wrong here?

Any ideas on what I can test next? Only thing I can think of is trying to get ahold of another psu + graphics card and trying them out to see if that removes the problem.

Any other ideas are welcome! :)

I got an advice from sweclockers.com (swedish hardware forums) from a guy telling me to do a CHKDSK C: F and then check for errors (no errors found) and then also reinstall the game I played the most at the moment which is crysis warhead. I did just that and it ran just now for about an hour but then it crashed again.

So that was weird. All of the sudden it lasted alot longer but it didnt solve the problem :/
 
I just remembered, once on my old P3, that I ran into "mysterious freezes" like you mention. After hours of looking what could be the problem, the answer was found... Weird, but found, lol.

It turned out to be the molex to my HDD! From time to time, the metal thingy that was soldered badly, barely made contact. So, from time to time, it made my PC freeze. I wish your problem would be an "easy fixable" one like that, but if you don't find any defective molex, then it could be heating indeed.

I still insist in the "defective PSU" thingy, but according to the test suit you made, looks like it ain't the PSU like i thought.

That brings the question: "why do PCs freeze?" And the 3 main answers: heat, power, defective part.

If i think of anything else, i'll post it right on, but on the mean time, i'm kinda out of ideas, dude =/

Esop!

Looks like im going to have to try and switch parts and test for defectivness etc :) Thanks for the help ill post if I solve the problem.

Just wanted to write that I finished crysis warhead after playing it for 3 hours straight just now. This is like magic... the pc only crashes during the eveningtime and then it can crash after like 5 minutes in-game. Weirdest. problem. ever.

I have quite a new Belkin SurgeMaster and the only thing connected to it is my monitor, pc and modem.

Other stuff connected in my room are just a few lamps and a laptop :/

I was also thinking about power problems but don't know much about that. If you turn on more things at night in the entire house and not just in my room could that affect my pc?

No idea how I check if my outlets are grounded but ill ask someone. Gonna have to ask if they share a circuit since I dont know how to check that either (I suck at electricity stuff :p)

The apartment I live in is very old I think yeah :/
 
Do the outlets have three holes, or just two?
A third hole is for a ground pin; assuming of course that it is wired correctly. There are testers available for $12-$15 that will tell you if your outlets are properly wired.

Tested if it was an electricity problem quite thoroughly now and that doesn't seem to be the case at all. Im starting to doubt ill ever figure this out :/
 
I got another idea of what might be the issue... Check the North bridge's temperature by hand. Some times the board sensors screw up and don't tell the true.

Touch every single component and if you can measure them with something, it would be more accurate. Carefull though, u might get burned, so get your finger close very slowly to the CPU HSF (and carefull with the fan, lol), Video card (on the back side) and the MoBo chipset.

Random freezes are a pain in the butt, but we can always find them and fix them. Keep trying and we'll find it :D

Esop!

PS: The North bridge is the MoBo's "big processor", it's very easy to find and usually is near the CPU/RAM.
