Black Screen when Computer Boots

Specs: Windows Vista
I'm having a serious problem with my computer; I think I've narrowed it down to the motherboard, but I'd like a second opinion before I spend the money.

Before I moved into my new apartment, my desktop was working fine; now, it just won't work. It will turn on, the fans will spin up, lights come on... but nothing appears on the screen. No POST, nothing. I've tried:

* A different monitor (both are VGA)
* A different video-card (both are DVI, PCIe)
* Three different, known-good VGA->DVI adapters
* The onboard video port (VGA)
* Reseating the memory, and trying only one stick
* Different, known-good wall-outlets
* Unplugging the HDD and CD-drive from both the motherboard and PSU
* Replacing the PSU

Has anyone had this happen before? Perhaps it's a known problem with this motherboard? Any advice!?

Here are my specs:

* A13G+ V3.0 motherboard
* 2 2-gig 800mhz DDR2
* 600-watt PSU
* two older Geforce video cards

Any chance there is an onboard video that it might have defaulted to?
Plug the monitor into that and see.

Reset bios if it has a jumper and return jumper or follow manual.

Try removing the RAM. If you get error beeps for the missing RAM, that's a good sign. It indicates that the motherboard and CPU are working to some extent, and the RAM is probably defective..
