I turn on my computer, and it finds my video card (apparently, because the monitor shows stuff), shows the energy-star logo / dell logo or whatever, and then the hard-drive-reading light comes on and it does nothing. It doesn't display "Phoenix BIOS" version stuff or anything, it doesn't try to read my RAM, it doesn't initialize my drives / keyboard, it just hangs. First time it did that, I took it apart and unplugged my IDE cables and it booted (read my RAM and keyboard and junk anyways, then it did nothing naturally because there was no OS to do anything with), then I turned it off and plugged the IDE cables back in and it booted fine. I used the computer for a couple hours like that. Then I had to reboot. When I rebooted it hung again like before. This time I unplugged the IDE cables and it still hangs. I took out my RAM and everything else I could think of except my video card, and it still hangs. Just sits there trying to read from a non-existent hard drive (or BIOS? whatever, the HD light flashes like mad) and does nothing. Is my motherboard dead? Is my BIOS dead? Is there any hope of fixing it?
