So here's a noodle scratcher for ya. I'm building a new computer for my folks. Now, I've built my fare share of computers, so I know what I'm doing to a degree. So I get everything in and settled, I turn the computer on, and I get a screen with some radeon junk on it, and then nothing. So I figure there's something goin on with the bios, and I switch some jumpers. Next time I boot, I get through the POST and everything's fine. Now, at this point, I need to enter the BIOS to change some boot priorities (need to install an OS off cd). I change what I need, save and exit, the computer reboots, and I'm back to a blank screen. I'm scratching my head, thinking the worst has happened to my computer, so I take out all the PCI cards, optical drives, etc.. Still nohing. Reset Jumpers. Computer POSTs, reboots, and nothing again. What on earth could be hapenning? I figure something is being shorted somwhere. Any help would be appreciated.
