Basicaly I am getting 2 types of errors, a random error that recovers in 1-2 seconds that says "A driver has stopped responding but has recovered" this is guaranteed to happen at some random point after i turn my computer on but only happens once, it makes the screen go black for 1-2 seconds. But also my computer is hard rebooting randomly during games, during internet surfing and I used a program called "who crashed " to get the following information

I really need some help fixing this, should I plug in my old 8800gts to see if it stops or is there something a little bit simpler to try first?

 

Its actualy at 651/1124, a tiny overclock but Ill find the specs for stock and put it there and see if it continues. I would disagree with the psu issue but it may be possible because I am running a few extra things since I got the card, more HDD's and such.
