Do you only have a one disk drive system?
Have you tried different (newer and older) drivers got the cars. There is nothing unique to a GTX 460. There are at least 28 sucessfull users of GTX 460's that have reported their results to the Premiere Pro BenchMark (PPBM5)
Maybe it is your power supply.
I agree will Bill here, your PSU is a very likely candidate to cause your problems. With only the CPU, video card, memory and single disk, but without fans, a burner or DVD player, without USB or FW devices, without anything that you left out, the minimum recommended wattage is already 510 W. Add other components that you did not mention and you easily need a 650W or more PSU.
So I switched my EVGA 460 SE out with my roommates Gigabyte 460 and his card has worked fine in my system for a couple hours now.
At the same time, I put my card into his system and within 10 minutes the exact same problems I was having started happening to computer, his display starting going in and out and the screen was flashing and his system automatically restarted. He has essentailly the same build as me with a 600W PSU.
Could it be a faulty GPU?? Any other suggestions?
It sure looks like it may be a problem with the video card or the PSU connectors to the video card.
I just checked and it looks like the GTX460 SE is a lower power GTX 460 (I could not find the exact specs) but it is a lower clock speed.
