I have a late 2008 Quad Core., 2GB Ram, Nvidia Gforce 8800 video card installed. After shutting down the system I get no video after a restart. This happened a couple of days ago and I did an Option boot and that seemed to fix it. Now, nothing. I have rebooted with "option", and without several times. I'm just wondering if I have a bad card or if there's anything I can do to fix it. I also tried moving the card to the other slot with no luck and tried the other output. The fan is spinning. Can someone help me please?!?
