black screen monitor for unrecognazing the vga card

One day my PC was working for 12 hours... Suddenly monitor had been turn off.
I reset my PC. when the wellcome screen showed,my monitor had been turn off again.
I showed my VGA card to a repairman... he try to fix it by BJ machine. He fixed it.. but after a few hours problem ( turning of monitor ) start again.

The point is here: when I install WIN7 monitor will turn off . but when I install win XP there is no problem. but when I try to install VGA driver in Win XP monitor will turn off.

I try my VGA card on other PC and there was the same problem .
I have this video card for 3 years.

please tell me what is the main problem of my vga card?
Thanks alot.
