ATI Radeon X800 PCI-E troubleshooting

[mmcdonalataocdotgov]

So, I am building the new system and it won't boot, apparently. Here are the specs:

Intel D925XCV mobo
Antec True Power 550W
Apacer 1GB DDRII PC4300 (x4)
ATI Radeon X800 256MB PCI-E.
etc.

The system apparently won't boot, but I am not getting any beeps. So all I know for sure is that I am not getting video. Nothing, blank screen.

I also noticed that when I try to boot with this set up, the KVM gets stuck and I can't move it off this system until I turn it off. It has been tested running directly to a monitor, though, and the same results.

I have a post for the mobo (after building hundreds, how many times can you remove drives, change PSU, reseat RAM, etc.)?

I have made sure that I have plugged in the proper power leads to the mobo, and I have plugged in the 2x3 power connector that comes with the card.

Any help?

Thanks,

Pull out everything but CPU, one stick of RAM, and video card? Reseat everything?

Beyond that, if you can't get it to POST and you're *certain* you have everything plugged in, you have bad hardware somewhere (either CPU, MB, RAM, or video card). The only way to figure out what works is to swap parts out with known good ones. Although if you don't get *anything* (not even a beep code), I would suspect the CPU, or the motherboard. Completely dead RAM might also do that (but since you have four sticks, you could try another one; it's extremely unlikely you have four bad DIMMs).

PS: these questions should go in General Hardware or Troubleshooting. Video is for things *specifically* related to video cards.
