I turned my dell 4550 on today and the computer booted up, went to the flash screen (the bios/dell logo) and then went to a black screen with a cursor and then went totally black after a sec or 2. Nothing else. The LED's on the back of the computer are all green and the light on the mother board is on, so there isn't a power problem. The fans run as well. I talked with dell tech support and they ran me through all the obivious tests, and told me it was my mother board. I don't think it is. It may be, but why would I be able to access the bios if the mother board didn't work?
Should I try re-installing xp? Any ideas?

That's right, the BIOS is obviously OK if you got the logo screen. More likely is that the hard drive has file corruption of some kind. Since you can't boot the OS you can't back up your important files using this machine.

Do you have files that need to be backed up ? If so try moving the hard drive to another desktop and backing up to a CD or DVD.

Your best bet is to try to reinstall the OS.

If no lights at all, probably power supply.
If lights flash and fans spin, but no beep and then it just clicks off, or sits there with no drive activity, then probably processor, or maybe motherboard.
If lights flash, fans spin, single beep , and then the hard drive keeps flashing, probably dead video.
