I had changed CPU coolers and when I tried starting my computer back on, it would not boot. I did not disconnect any cables nor did I reseat the CPU or take out the RAM. When I pressed the power button, all that turns on are the fans for only half a second or so, then they would stop and nothing happens.

After some research I thought that it might be a PSU problem so I took out a PSU from another computer and replaced all the cables and the same thing happened so I'm sure it's not a PSU problem.

After playing around some, I removed the CPU and turned the power on. Everything turned on like it was about to boot up and everything was running in the sense that it stayed on, but when I had put the CPU back in, it reverted to the same problem.

Could it be a problem with my motherboard or CPU? Or is there something else that could be wrong?

Mobo: Gigabyte GA-P35-DS3L
CPU: Intel Core 2 Quad Q6600
Heatsink: COOLER MASTER Hyper 212 Plus
RAM: CORSAIR XMS2 4x2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
PSU: Corsair eXtreme Power Plus RS-550-PCAR-E3
GPU: EVGA 256-P2-N429-LR GeForce 7200GS
Case: RAIDMAX Altas ATX-295WB

Were you grounded (using an ESD wrist-strap) while working? Or did you at least minimize the chance of ESD? You may have inadvertently knocked something loose (like RAM seating) during all this. If you have a POST display on the motherboard does it display any code? If not, do you have a mobo speaker that you can attach to see what beep code (if any) it gives?

Yes I cleaned the CPU with ArctiClean Thermal Material Remover and Thermal Surface Purifier. I also applied the same thermal paste I've always been using: Arctic Silver 5

I had tried with the old HSF and the same thing happened. If paste did get into the socket, how do I go about cleaning it? Or is it ruined now?

I did not use an ESD wrist strap as I did not have one so it's quite possible static might be the culprit. If it was the RAM I made sure to reseat it, but as I can't even get anything on the screen, there was no POST display.

I don't think the motherboard beeps at all.

I purchased a used motherboard and cpu on the cheap and will see if any of those will help me find out what malfunctioned
