My GPU is working, but I don't get a display after installing a new CPU cooler.

I recently bought a new CPU cooler, and installed it. After I finished and booted up, I had no display, not even the BIOS screen, but everything else is working just fine inside the case. All fans, GPU fan, etc are working. my GPU has a red LED warning, if I don't have the PCI-E plugged in, and that light is currently off, so I know It has sufficient power. I just put that GPU in this computer that I'm currently using, and it works just fine. I bought the same Motherboard off amazon, thinking it was a MB issue, as my friends suggested, but I am getting the same result on the new MB. Could I have tightened the CPU cooler to tight? Note that I have had this build since August 2012, and the only new addition since then was the CPU cooler last week, and the case, but It was working in this case before I installed the CPU Cooler. The computer I'm currently using to write this, is using the same CPU cooler. I installed it on both. Works great on this computer.

I think your friend is wrong since no working GPU no display BIOS or other. I really do not know what is wrong apart from guessing in my last post but used board just does not sound to good. Disassemble CPU again you may see if there was a short.
Your original board should be still in warranty though so why not claim it.

I have taken everything apart, and put it back together about 4 times now. Still the same result.

I just now did what you asked, and I am still getting the same result. My other GPU won't work in the problem computer. I already switched motherboards yesterday, and still the same problem. So is the problem my CPU? I did get some thermal grease on the bottom pins when installing that CPU back into place. I cleaned it best I could, but it was fairly hard. Could that have shorted something?

I did order a used board, but it was supposed to be in working condition. A friend of mine told me that biod wouls still show up on my monitor even if the CPU went bad, so does this mean the socket shorted the pci slots?
