Did you install the motherboard in another computer enclosure ?
Perhaps the computer enclosure has a brass standoff which is
shorting to the bottom of the motherboard ? You could try
removing the motherboard, and testing the motherboard, PSU, and
other components, while they sit on your work table.
Your motherboard manual mentions that slot5 cannot contain a
bus mastering PCI card, so the video card should not go in
slot 5. Perhaps you could test the PCI video card in the
other slots, one at a time.
Does the computer work, if both the AGP _and_ the PCI video
cards are plugged in ? Perhaps you can work some configuration
magic while both cards are installed, make the PCI card the
primary output window, then remove the AGP card.
Also, in the BIOS, there is a submenu called "Resource
configuration" and an item "Primary Graphics Adapter" [PCI].
It might currently be set to [AGP]. Note that, if at some
future time, you do the "clear CMOS" procedure, the default
BIOS setting will return to AGP, which might require you to
temporarily plug in an AGP card again.
PCI bus failures are not too common, so maybe you can get the
board working again.
If you want to try clearing the CMOS, remember to unplug the
computer first, before trying it. Some motherboards can be
damaged, if you clear the CMOS, while the board still has
+5VSB running on it. Unplugging the computer first, will
protect it from that problem.
Just some guesses,
