Does that happens when u play any kind of game or just a single game, if this happens when u play any game and if it does not happens while working on ur PC then it must be a fault in the video card(not sure bro, need more info)....
I guess this might be a problem with ya VGA! If the video memory is insufficient to run ya Game, it might give probs! But if u give more info on this Anusha will sure help u!
Might b ur VGA.chk ur VGA..If its full of dust give it a good clean ,slot too, and fix it correctly back..If it still isnt an internal error with da vga.

Lack of VGA RAM doesn't cause this kind of a problem. It will only slow things down but if you have 256MB and NOT an very high end video card, this is not applicable.
Could be CPU overheating
Could be a driver issue
Could even be a sound driver problem
