Graphics Card Fail at 76C
« on: June 02, 2009, 02:31:01 PM »
Lately when I've been playing games (not necessarily graphics intensive ones, like BF1942) my screen becomes full of multi-colored squares, forcing me to reset the motherboard.

I have a GTX 260, Core 2 Duo processor and a 630W PSU (XION Simple Power 630W ATX Power Supply). 

I decided to use FurMark along with RivaTuner to stress test/monitor my GPU.  On the stability test, whenever my core temp reaches exactly 76 degrees Celsius (not particularly hot) I get a full green screen and have to reboot.  My card idles below 50 degrees and CPU temps are normal throughout.  I can run the benchmark test fine (though the core temp doesn't reach 76).  Fan speed is set to 100%.

I used to be able to play games like Far Cry 2 perfectly fine, and the only difference between now and then was an extra hd.  So at first I thought it was lack of power.  However according to all the PSU calculators I tried, I should have more than enough power for my system.  I built my computer about 4 months ago and haven't had any problems until now.

As my card obviously isn't overheating, the only thing I can think of is its not getting enough power, which still doesn't really make sense unless my PSU is faulty.

Any ideas/help is appreciated.

P.S  When it failed running BF1942 the fan speed was only set to 40%.  I haven't reproduced it with that game since adjusting fan speed.  Still reproducible with BF2 and FC2.

Did you create an overclocking profile with Rivatuner? If so, go back to stock clocks.

Nah, I've never overclocked it.

Have you tried another PSU (Seasonic, Thermaltake thoughpower, ...) ? The theoretical power of your PSU is good enough but you have to be sure of its quality.
