Man of Honour
About a week ago, my graphics card started locking up during gfx-intensive work. It started with Oblivion, but has slowly got worse. When the problem started it would play an old game like Postal 2 at 1600 x 1200 without issue, now even that locks up. I can run Firefox for hours, but more than ten minutes of Media Player running movies will lock up the graphics.
First of all, please note that it is ONLY the gfx which is locking up: if I access the machine via another on the network, everything is fine, but the screen is frozen. It will respond to ctrl-alt-del, but only very slowly - usually after several minutes.
The card is a BFG 8800GTX OC. Clocks are default: 600/900, and the fan duty cycle is 100% for everything. The GPU does not appear to be overheating: temp monitoring programs say that the temp never goes above 58oC, and is usually lower than that. Right up until the temp monitor display freezes along with everything else, anyway.
It happens with 158.19 and 158.22 drivers, but never used to happen with either. Note that nothing (hardware or software) was added in about two weeks before this happened. The Windows logs shows no errors except to say that the app (Oblivion) was unexpectedly terminated (because I used ctrl-alt-del to kill it)
The less the gfx card has to work, the longer it takes to happen: Oblivion at 800x600 and lowest settings takes about two minutes, but 1152x864 and highest will often lock during the load screen, and certainly within seconds of finishing loading.
Turning the gfx clocks right down has no effect. Turning the system oc down has no effect. Turning the RAM settings down has no effect. I can run SuperPI to 32 million DP with no issue.
System is:
E6600 at 400 x 9.0
2GB OCZ 1066 RAM
Asus P5N32-E SLI
etc
Antec TruePower 650W.
Windows XP Pro.
Edit: yes, the fan is turning! RivaTuner says 2800rpm IIRC.
My immediate thought is that the card is borked. My next plan is to move it to another machine to see if the problem moves or stays, but unfortunately that means driver playing as the other machine has a 7900GT in it. And changing the drivers means that I can't be sure it's not a driver issue - although I'm 99% certain it isn't because it's over a month since I loaded the 158.22s and the problem only started a week ago or so.
All the googling I've done throws up cards which are overheating, and this does not seem to be.
Anyone have any ideas?
