Troubleshooting?

Anyone with motherboard experience?

I have a Gateway computer (conveniently 1 year and 2 months old). Two days ago, my NVidia 7800GT graphics card started messing up on me. I pulled it from the system and switched to onboard video. I knew I'd want to test the graphics card to make sure that the board wasn't getting glitchy on me.

The next day, the onboard video started messing up. What happens is the computer would power on, but then (before reaching the OS) the screen would become jumbled and illegible. Now, the computer will not make it past the boot screen without messing up. Note, that at this point, the computer stops responding.

Also, when powering on, the DVD drives do some crazy light flickering and whirring that just sounds like the signal the MB is sending isn't quite right. I've even tried booting barebones and got nothing. I have three different stick of Ram, and I've tried each independently with the barebones setup.

Does this sound like a controller error on the Motherboard? I'd like to think it's the cheap-o Gateway MB that's failing and not any of my name brand equipment.

SPECS:
AMD X2 3800+
2x512 MB Ram
1x1 GB Ram
2x 1-250 and 1-200 GB Western Digital Hard Drive

The motherboard is a Foxconn C51GU01 Motherboard

I would try another power supply. Even if you were to test the output of that one, it could check out fine but may not hold up under load.

Although it's not unheard of, motherboard components, other than video and sound chips, rarely go out.

Have you tried the video card you took out in another machine? Just curious. If the PSU isn't putting out enough volts it could fry components.
