I'm up at 2am because my computer is down. Help me get it to boot!

My PC was working fine until tonight. I rebooted to fix a BIOS setting (to enable the onboard Ethernet port) and since then it won't boot properly anymore. The PC POSTs fine, keyboard is initialized, I can enter the BIOS setup fine and make any changes I like, then save them. After that, the screen blanks and I'm left staring at a blinking cursor in the upper left corner. Nothing happens. How can I troubleshoot this and fix it?

Keyboard is now nonresponsive. As far as I know the PC is not even trying to boot. If I hit "F9" to select my boot device, it doesn't show me the boot device screen. Every time I boot, same problem.
This is a 1 year old PC assembled from parts. Biostar TF-7025-M2 motherboard, AMD Athlon 64 X2 5000 dual core processor. 3GB RAM, Antec 350 power supply. Onboard video. Maxtor SATA hard drive. Panasonic DVD-writer. IBM keyboard. I've disconnected everything else. I'm running Ubuntu 8.04 on the system. GRUB should be loading from the MBR on the hard drive and displaying options, but it is not.
The BIOS settings include a built in burn-in-utility (memory tester) which I have tried enabling. It won't run it.
I've tried booting from the hard drive and booting from several different rescue CDs - Ubuntu Live CD, Ultimate Boot CD, with no success.
I've tried clearing the CMOS via the internal jumper. CMOS is cleared but this doesn't solve the problem.
I'm thinking that this could be:
a) bad power supply (can run BIOS but can't boot?)
b) bad motherboard (but wouldn't I get some other indication of a problem?)
Any suggestions how to troubleshoot? I don't have a spare power supply or motherboard to swap in, unless I'm willing to cannibalize my Windows PC (can't do that!)
