Driver Has Stopped Working And Has Recovered

I keep getting that error while playing Skyrim on my GTX 295. It's not just Skyrim, it happens with Crysis 2 VERY often, like every 20 seconds, it happens with Deus Ex, only once though, as it crashes to desktop afterwards. I have tried every possible driver combination, i updated to the latest beta driver and it still happens. I ran the program in XP compatibility, ran it in Iobit's Game Mode (which disables some services), and as Administrator mode. It still happens.I ran it windowed, and also ran it as Single GPU card (which reduced the frequency of this happening, but didn't stop it), ultimately, i ran out of ideas.Whenever i turn my computer off for 15 minutes or so, the game runs fine for 3 hours at least. My first thought was overheating, but i used EVGA Precision to measure the temperature, and it didn't go higher than 60 C when it crashed. It did, however, report a sudden spike of GPU- A usage to 100% when the error message appeared, but B remained constant.
