EMachines T5802 MB Fried due to VGA output?

Specs: Windows xp, 512mb
I have a friend who's eMachines T5802 Desktop PC seems to have a MB Failure. He recalls that he tried to connect the PC to his Vizio 42" with a Standard VGA cable. When the pins from the VGA and the Vizio input VGA touched, a big spark arose. He tried once more and same result. When he tried to power on his PC with his regular monitor, he then had a problem.
The PC turns on, motherboard will power up with green LED lights on, and blue LED power button for the PC will all power, and you can hear it start up with the fans running; all functional.
You can tell it halts as soon as it boots up, because you cannot hear any boot up sounds, and the keyboard doesn't respond, nor does the power button being held 10 seconds or more.

Any suggestions?

Ps: I am aware that eMachines have poorly designed MB and PS, that fail occasionally.

Could be just that the VGA output got fried. You can try installing a video card depending on what slots are available (PCI, PCIe or AGP). You could also try a different VGA cable first in case the cable got damaged. If that doesn't work you have MB damage but it is more likely the first two options will give you your display.

I am going to try that but I didn't think it would do much because it seems the PC isn't booting up correctly either-way, because it doesn't power the keyboard on and the power button does not react after it is turned on; ie; we have to manually unplug the PC from the power.

Both the TV & computer *should* have at least been turned off before he connected the cables...unplugged would have been better. Do you know how he went about hooking things up?

When he powers up the PC, does he get any type of beep code?

I'm pretty sure they were both turned on when he plugged them in, which helped provide the spark.
No beep codes at all when started up. The PC turns on and just stays on without any signs of action or loading. Like I mentioned before, the power button also does not respond.

Yeah I am guessing the MB is fried (should have read better). Both the TV and the PC should have been off when the connection was made. Static electricity is known for killing MB's and an arc like that isn't often seen in my experience.
