So I've been having this issues for awhile now, but never figured out what to do to fix it. My graphics drivers crash and get recovered by windows, sometimes it happens once and then it stops. Other times it keep crashing till it freezes or BSODs.
I've checked my RAM and one stick was bad. Still happened after I removed that bad stick. I've tried many different drivers from nvidia also. Could it be a bad HD that causes it? Some days I have 0 issues others I have lots. Usually after a fresh restart it stops for that day. Not enough power with 650w? I'm running 2 monitors also, 23in Dell and 20in HP off the single card.
