I have a Nvidia GTX 560 Ti bought about a year ago I think, and since a few months ago, my graphic drivers crash every once in a while. Sometimes they recover after a few seconds and sometimes i'm forced to restart the computer. The crashes usually occur in the middle of a game or while watching a youtube video. I've seen that other people were having driver crashes during some of those games, such as Battlefield 3, but my drivers crashed on time during TW:Shogun 2, a few times on Team Fortress 2, Overgrowth, Mass Effect, Blacklight Retribution, etc. I think that if those crashes keep on happening, I'll format my computer although I am reluctant to do that. I've already tried multiple times to downgrade my drivers, doesn't seem to change a thing.
My specs are:
Intel Core i5 2500 @ 3.4 ghz
My power supply is an Antec 550W, I don't remember the exact name though :S
My monitor (if it helps) is a LG L192SW (19", 1440x900 yeah I know it sucks, i'm moving to a 1080p monitor soon though)
2x4 G. Skill whatever it's called, @ 1300 mhz methinks.
