I was working on my computer last night, rebuilding it to reseat eveything and all the connections. When I was done, the computer powers up but I see nothing on the screen. There are no beeps either. I tried the video card in a different computer and that works. I don't know if it is either the motherboard or the processor (since I accidently dropped the CPU off the table

, there was no visual damage or bent pins but who knows).
Anyways I'm stuck now feeling pretty stupid, without a computer, and with no idea what to do. I have already gotten a RMA from Newegg for the motherboard and I will be calling AMD.
Anything else I can do?
Thanks
