Boot to Windows, no video output

Gigabyte motherboard / Ga-p31-ds3l

Specs: XP pro SP3

I've tried everything I can think of. Here is the problem.

I shut my PC down last night, not one problem. Today I
boot it up and it boots to post fine. I hear the Windows
chime, I can access shared folders from my Mac, I can use
the keyboard to shutdown and it plays the shutdown
chime and shuts down no problem. But , no video at all.
Not even for the BIOS feedback.

At first I thought it was a video card issue and replaced the
card with an older one and it did the same thing. Started
searching forums and found nothing really, so I reset my
CMOS, pulled my RAM, etc. and nothing changed. I
thought it might be a monitor resolution problem but I
would still be able to see the BIOS screen before
Windows loads. I use a KVM with a Mac and my PC and
the monitor is fine, using as I type this. Switched the KVM
cables and it works on the Mac on both outputs, but the
PC is in sleep mode (no signal) from boot up to shut
down. I am at a loss.

I've read some forums and please don't tell me it's my
MoBo, or CPU, or RAM because it boots into Windows XP
Pro SP3 fine. I just get zero video signal. Any help would
be appreciated.

How can you be so sure it's not your mobo?

Did you update the BIOS? Was the other video card you tried a PCI card in a different slot? Or was it also an AGP or PCIex (you didn't specify) in the same slot as the original card - and if so, what makes you think that slot isn't dead?

How about monitor directly to the video card instead of using the KVM? Adding a KVM adds signal loss to a potentially dying video card too - might work great on a perfectly operational Mac, but not to a dying PC's video card.

I can't be 100% sure it's not the MoBo, but I never move the PC so that seems unlikely. The Mobo is less than a year old.

I have never updated the BIOS, no need to, it ran great until today. I only have one PCIe slot and no
AGP. I placed an old 7600 GT and got the same problem.

I did connect the monitor directly to the PC and got the same

I do tend to go through video cards rather quickly, it seems I get a new one every 1.5 years, and I am due in a few months. But why would my older card show the same symptoms?

I only use this PC for games, I have nothing other than Speedfan (temp monitor) and AVG free installed.

Does the motherboard also have on-board video? If so, try that port too.

If the monitor proves healthy and both video cards test well in other machine(s) then the only possilbe culprit realistically would be the PCI slot. If, of course, you have an on board video adapter then that would test that theory.
