And it powers on, but there is either no video output....monitor just shows the 'no input signal' screen. Video card has VGA and Svid, nothing from either. From unhooking/replacing, I've found that the problem is not from HD, optical drives, floppy, power supply. I haven't happened upon failure in video cards, mobos or RAM before, so I'm not sure which I should be looking at here. There's actually another computer (my parents') that is doing the same thing, but has onboard video. Is the problem obvious, or is there an easy way to find out? Besides what I already listed, I don't have extra parts to play around with to test out the originals.
