No display when computer turned on

I was workin on my computer when it just shut off. When I rebooted the computer everything powers on but the monitor doesn't receive a signal. All the fans in the system are working so I know the board is receiving power. I know for a fact that my monitor is good and I tested a different power supply in the system as well to make sure that wasn't the culprit. From what I can figure, I either have a problem with the graphics card or more likely the motherboard. Some of the capacitors on the board had some crust on the tops of them but I couldn't tell for sure if they had busted. What do you guys think?

My specs are:

P III 667 MHz
VIA CPV4-T Motherboard
16 MB Nvidia card
20 GB Fujitsu Hard Drive
256 MB RAM

Not good, not good at all....

/shakes his head sadly at the demise of a once living, breathing motherboard.../

Yeah, I think I can assure you that those capacitors are goners. That crust you see is from the gel inside heating and swelling the cap while leaking to the top. That X across the top is there to vent pressure and keep the caps from exploding. Those caps are in the phase circuit that supplies the CPU's Vcore...when they short internally...even a little, that affects Vcore, and the CPU fails.
