Greetings all, I'll cut to the chase here as I'm getting pretty much to me wits end trying to figure this out. (Apologies for the wall of text)
So here goes, yesterday i tried to play Battlefield 3 and it crashed after about 2mins game time (no visual errors, sound continues and PC simply locks up). So I thought strange and tried Crysis 2 after a reboot. Pretty much same thing, so I started becoming more concerned and tried Diablo 3 (which is what i have been playing pretty much consistently over the last few weeks) and it worked fine, no errors or visual artifacts or crashes. So i tried Just Cause 2, instant hard lock up as before, Borderlands 2 no problem.
So this morning I figured it may be my OC, so i removed it and went back to default speeds on CPU & Ram and tried Just Cause 2 again, seemed okay for 5 minutes play. So I when i then tried Diablo 3 i was starting to get artifacts until it locked up. So naturally I'm thinking my GPU is dead which is a shame since I've only had it under 18 months and not done any overclocking on it. So I Try a few the other games again and they start crashing with artifacts present over the whole desktop/screen and not just the game (i have multiple displays and these also show the same artifacts). Okay so i thought I'd try MSI Kombustor to see what temps are doing and if it causes any problems. Ran perfectly fine no trouble for 10 mins and reached 85'c tops with 75% fan speed. So loaded up a game and bang pretty much instant fail. It was then getting to thwe stage where the computer would start to freeze on the desktop with no programs loaded and I guessed its going to be the end of my GPU.
I then proceed to try something else, I take my 570 and put it into another PC (Q6600 680i board with 64bit Vista Premium). Loaded up windows no problem, this PC didn't have any games installed so i downloaded and tried 3D Mark 11. It completed a couple of runs through this. I then tried the MSI Kombustor again and hoped to see something but again it worked fine. So I ended up installing Steam on this PC to try out Just Cause 2 benchmark. It completed about 80% of these runs with the occasional "display driver has stopped responding by recovered" message but never a crash similar to what i was expecting or had before.
I then removed the PSU from this PC and tried it on my original pc with the 570 back in it again. Loaded up JC2 benchmark and it crashed after about 10 seconds. I tired this a couple of times but couldn't get the benchmark to complete but my desktop stability was back (as in it was no longer simply crashing while idle).
So now even more confused I tried an old 9600GT, worked fine through a few tests and no crashes or errors etc.. So I thought perhaps its the PSU then.
Before I was going to spend money i though i'd try my original system again to be sure. To make sure I didn't have anything to doubt i reset my bios to default settings in case I had part of my OC lurking somewhere. Low and behold it now worked, so I thought I'll try a few Just Cause benches to see if anything occured. Nothing, so problem solved and I played Diablo 3 for around 4 hours straight.
I then tried BF3 and it crashed in 2mins again. Just Cause 2 benchmark, which had been working previously crashed near the end of the bench. So I figured I'll have a look at the CPU and try stressing that in case its a cause. Intel Burn Test Very High stress level completed with no problems and highest temp was 65'c. Okay I'll try Kombustor again. worked flawlessly for 15mins. I'll try Memtest then, passed the test with no errors (note i will be running this again all night for a better test but I had to give it a run through before posting this).
So now I'm really stumped as to what the problem is. This seems to have literally developed overnight as up until then i hadn't had any problems with BF3, Just Cause 2 or my PC in general. I haven't changed any hardware, my drivers are the latest Nvidia WHQL 306.23, motherboard drivers & Bios at latest. Im really really stuck for ideas now as to what is going on.
I'll try some more testing and report back.
Deepest thanks to anyone who manages to read all of the above, but I have tried to be clear as to what I've already done so that we're not doing the same things over and over.
