Problem with nvidia 8600 gts card

Hi hope some one can help me, i am almost certain that the problem i'm having is down to the graphics card. My mother board, cpu, ram, psu & graphics card are all new.

The problem started as soon as i installed the nvidia drivers that came with the card. I would load a game and it would work fine for 10-15 mins and then the screen would just freeze, forcing me to re-boot. At this point i was still using xp so after trying all the latest drivers on the nvidia site i decided to change to vista as i had bought the oem version anyway.

I upgraded my system from xp to vista and as soon as i installed the nvidia vista drivers i get green squares all over the screen. Screen shot of problem. At first i thought it might be a problem with some of my old xp drivers so i formatted my C drive and did a fresh install of vista. The display is fine when using standard vga drivers but as soon as i install the nvidia drivers i get the same problem.

I have tried the latest nvidia drivers including the beta one but still the same problems. Have also updated my bios and chipset drivers with no joy.

Any idea's? please help this problem is driving me crazy.
