I was moving my hard drives and I needed to take the cpu heatsink off (stock amd one). and when I did the cpu came with it. I finished moving things around then put the cpu back on but now it wont boot. The pc light up and the fans run. some of the cpu pins were bent and I tried my best to fix that.

Spects:
-AMD FX-4350 Vishera 4.2GHz
-Team Dark Series 4GB
-GIGABYTE GA-78LMT-USB3
-Dynex 520-Watt ATX PSU
-Rosewill FBM-01

It's unlikely the motherboard is damaged. The socket does not hold the pins as strongly as others are implying, but I do suggest removing the processor and verifying all pins are as they should be. You could have missed one, which has now bent over, or you could have had one become detached from the CPU package, which would now be stuck in the CPU ZIF socket on the motherboard. I suggest going row by row in the socket, perhaps with a magnifying glass, to verify you didn't separate a pin from the CPU package. If that's the case, you will need to extract the pin before installing any replacement CPU. If you can come up with a way to reattach any separated pins, I suspect the CPU would work, but any method would have to be able to handle...
Remove the CPU again and check that you don't have any missing pins. If you have pin(s) missing, they are likely still in the ZIF socket. If this is the case your CPU is done. You might be able to salvage the motherboard if you can get the broken pins out of the socket.

The best way to straighten bent pins is to get a mechanical pencil, remove the lead and slide the tube where the lead comes out over the pin. Slowly straighten the pin.

Hope this helps, good luck.
