Details of my video card: PNY 'VERTO' GeForce 8600 GT, 512MB video card. PCI Express. (not 2.0). I just got this video card today, along with my 1g RAM stick... I plugged the RAM in, and rebooted the computer, everything worked fine. I plugged the video card in the PCI Express slot (the only one that's available), and it doesn't work. "What exactly happens?" you might ask... The card gently and smoothly inserts into it's seat, and clicks down as it should... But when I plug everything in where it should go (and yes I put the monitor cord on the new video card), the screen tells me that it's not receiving a signal from the monitor. It tells me the Monitor is on, but it still doesn't work. There is no 'beep' or anything. My power supply is perfectly sufficient. I can't find the area in my BIOS that allows me to change my video display to on-board or PCIE(PCI Express). Maybe i need to flash my bios? Update it? I have no clue, but my temper is flaring, and if i continue messing with it with no positive results... I'm going to break it. So please help? It just...don't...freaking...work.
