ECS P4M800PRO V2 bios problem

[gandg]

I have an ECS P4M800PRO V2. It was working fine, until I loaned it. My buddy tried overclocking it. When he did, the screen went black on reboot. I have pulled battery and moved bios pin. Neither have worked. Is it my video card? Is the motherboard shot?

You need to explain better. What is the computer when its trying to boot?

When you push the power button, I can ear it beep. My monitor says "no image" and never comes on. I am thinking the integral video card is cooked. He upped the voltage to the RAM and processor, but did nothing to video.

I also tried putting my xp disk in and booting cd. The screen never goes to post.

do you have access to any old PCIe card?
