both my power supply fan and the processor cooling fan were caked in fluff/dust/scum. It was so bad that I couldnt see through it.
Is it possible that because they were not cooling the processor it has overheated and broke?
This is a pic of my processor and the black you can see seems to have been a covering that was over it. What i want to know is whether this is normal or likely to have crashed my PC.

Also, when I turn my computer on all the fans start up, the motherboard lights up but that is all, no image on the screen and no beeps like it used to.
Cheers for any help, Kyle
Edit: I forgot to mention that when trying to put the processor back in its slot i bent 3 of the pins so its useless anyway, im just posting this because if its overheated is the motherboard likely to be bust?
