I have an HP Pavilion desktop with this Pegatron Socket AM2 motherboard. Computer wouldn't boot one day, and troubleshooting led me to believe that it was a bad SATA controller - a common problem with this type of machine/motherboard.

I found the exact same (refurbished) motherboard on eBay and swapped it in, but now when I try to boot it says "Unsupported CPU installed." So now I can't even get into the BIOS. I'm at a loss for why the same processor in the same motherboard type would have a problem. Any ideas?

This is my main computer - life is at a standstill. Please help! Thanks.
