Laptop LCD keeps turning off

[Gabriel_Knight]

Any time I am doing anything graphically intensive, my LCD likes to just turn itself off. It happens regardless of whether or not I'm playing a game, or just surfing the web, although it seems to happen much more often during a game. I am not sure if this could possibly be the actual LCD screen itself or maybe the video card? I'm not sure. The only fix I have found for it is to shut the lid and open it again. Sometimes it fixes it for awhile, sometimes only for a second or two. I'm running Windows 7 Ultimate, 2gb RAM with an ATI Mobility 512MB X1700...yes, one of the only cards with absolutely no drivers for it. Good pick on my part...TIA

Figured out it was a laptop when you said:  "...shut the lid and open it again..."

•List as much about your computer as possible.
