Basically I took out my cpu fan to clean it and the cpu was stuck to the heatsink and fan. So i prised off the cpu an manage to bend a few pins. I straightened them all with my credit card (took me like 2 hours) but i snapped a pin. I managed to get the cpu back in the zif attachment and pulled lever down. Now when i turn computer on it does'nt display on screen and wont power off with power button is that a dead cpu??
also i applied new thermal compound will that matter? Any help appreciated

The CPU is most likely dead now.

I took it back out and looked at the pins and can't see any missing (I checked for around 15 mins) But im sure i seen a little piece of gold wire pin fall out when i was straightening them the other day. It could be half a pin missing. Anyways when i put cpu back in it started nothing on screen thou but i could hold power button and power it off which i could'nt do before.
I checked every connection but still no display. So i took cpu out and reseated back in now its back to itself where it wont power off by holding power button. Still no display. Also keyboard not working but mouse and that is?? Which leads me to believe if i have snapped half a pin off could it be a pin that links keyboard/display is there a pin that controls them together amd phenom ii x4 9550. Could anyone confirm any of this it would help me loads.

If you broke a pin, the CPU will not work.

As for your keyboard not working, I suppose its possible that the lack of the pin (if it broke off) might have caused a short in your motherboard. However, that is unlikely.

thanks Neil.B for quick answer. Would a dead cpu stop my computer bios showing and stop it turning off by pressing power button?? Is there anyway I can check without buying a new cpu?

If your CPU is dead, nothing will display on screen. The CPU is one of the 4 parts the computer uses to display video. So, If your RAM, CPU, Video Card, or Motherboard are dead, video will not display on your monitor.

As far as the power button problem, thats usually either a motherboard issue or the switch itself. Try jumping it and see that works. If it does, id say your switch is bad. If It doesnt, your motherboard might be failing as well.
