System went dead ... need rescue!

[careless]

I have an Abit KA7 that was running a Athlon 650 @ 754 for 10 months.
Everything was OK, I was surfing the web, and then all of the sudden, the video went fritz. I reset the system with no luck. I powered down and tried to reboot... nothing. Opened her up, pulled all the boards and rebooted to nothing. Reset the bios, still nothing. Reseated the CPU .... nothing, not even a beep code.

I've pretty much narrowed it down to faulty KA7 motherboard, dead Athlon 650, or bad power supply. Any suggestions on how I may narrow it down further, or what else to try? The mobo and CPU are still under warranty, if I only knew which part to RMA!

Any suggestions welcome.

I doubt it's the CPU, could be the MB though. when you turn on the computer, does your HD/FD spins up? that's a quick way to see if power supply is good or not.
