The main card in my pc right now is a gtx 260 core 216. I was looking to use the 8800gt that i have sitting around for a dedicated Physx card. When i install the card and start my computer the monitor stays off. I can hear a good post beep and then windows login screen load. What am i missing??? I have not to long just learned about this and cant find any strait answers for my questions. All i have to do is snap the 8800gt into the board and plug in the 6pin connector and start the computer???
