I've been having an issue with my EVGA GTX 260 SSC. It worked fine from when I brought it (Feb) till around August, when it started crashing randomly with a full colour on the screen (when first loading a game, or even hours into a game, although the crashes became more frequent until it would crash all the time within a few minutes, it even crashed once on watching an episode of South Park). I RMA'd the card but EVGA didn't find anything. In the meantime I was using my 8800GTS with no probs for months, and now I've clean installed Windows 7 and am still getting crashes with any driver.
There are 2 things that I think could be causing it; temps and power, and these are the tests I did for each:
Temps:
I've run the card at stock SSC clocks with 100% fan and the case side off, temps never go above high 50's - low 60's, and it crashes.
I've run the card underclocked with auto fan speed and case side on, temps hit low 70's but fan stays at 40%ish, no crashes, so it's not heat related.
Power:
I used to run the card undervolted at 963mV instead of the normal 1063mV, which worked fine for months until the crashes started happening. However all tests now are at stock voltage settings, so it's not an undervoltage issue.
I've tried the stock SSC settings with my CPU also set to stock settings, and I get crashes, so it's not the system's overclock (100% stable with my 8800 anyways).
So I'm left to believe that it's either the card itself (but EVGA found nothing wrong with it), or the PSU is dying and cannot provide enough current on the 12V rails (must provide enough for the 8800 but not enough for the 260), although I'm pretty sure this isn't the case as it still crashes when my system is not overclocked.
Anything else I can try?
