i have an abit ag8-v (915p) motherboard with a 3.0Ghz p4, an x550 and 4x512Mb of ram. The system boots, i can hear the hard drive turn on, but there is no picture on the display. I tryed the graphics card in another pc, it works fine. Ive tried clearing the bios, and using a different psu, does anyone have any ideas??
