It sucks, but at this point if it was me, I would remove the CPU and be absolutely sure pin 1 is where pin 1 is supposed to be. If the CPU was never removed from the socket I would make sure you didn't get any of the thermal past on the motherboard etc. It is conductive. Don't over apply it either, you only need a very thin layer. I say this for the benefit of anybody reading this thread and its not meant to imply that the OP doesn't know what they are doing. When I don't know somebody I try to cover all the bases.
Quoted for truth: Failure to POST is always a sign of broken PSU, CPU or Mainboard. RAM, Graphics Card or HDD give at least beeps or (in case it is not the graphics card) show some kind of error message.
I have had the same thing and it was also overheating damage. Lost my old Athlon64 3000+ to that.
I have also lost a CPU because 1 (literally only ONE!) pin was bent. When I checked the CPU and noticed this I got a tweezer (sry if this is the wrong thing, in German it is a Pinzette) and tried to bend it back. Sadly, destroyed my CPU by ripping that thing off.
The only way to really conclude if the CPU is at fault is trying to run it in another PC.
