I'm using an HP Pavilion a1012x and I was using a PNY GeForce FX 5700 VE 256mb video card. But all of a sudden my monitor would say "no signal" and the screen would stay black. I just purchased a Sapphire ati x1650 pro 512mb agp video card and I thought I would be able to just pop it in and that's that, but I was wrong. I'm now reading that I need to uninstall my last cards drivers but how can I do that since I can't get to my desktop. Please help. thanks in advance
