Hello Everybody, I got a serious problem with my video card: Geforce 6600 GT 128 DDR3. Whenever I start a game, the game will start first. My LCD monitor then shows "No Signal". After that, my machine will restart itself. I don't have any problem with runing any other applications, such as: AutoCAD. I tried two games so far. One "Nascar Thunder 2004"; the other one is: "X2". Both of them came with the video card. The configuation for my machine is: Inter PIV 3.00 GHz Asus P4P800-E Deluxe Kingston 1G Memory Geforce 6600 GT 128 DDR3 Video Card Dual LCD Monitor I know this doesn't make sense. But trust me, it does happen to me. Would it be a conflict between the motherboard and the video card? How come the video card works fine with other applications but games? Any comments will be appliciated.
