Default E8400 overheat

I recently opened up my tower to clean out my dust vents and make sure everything was still ok. Anyway, in the process I removed my heatsink/fan to clean of some dust and I put it back on, well, not securely apparently. When I turned on my pc I got a CPU overheat message, I didn't think much of it. My PC was on for about an hour and then I was checking a few things in PC wizard and noticed the processor was running at 100 degrees celcius. I turned it off and re-installed the heatsink/fan and cranked up the fan to cool down the processor. Anyway, it runs at 35ish degrees now but I am seeing drastic performance decreases and a lot of freezing/errors. Could my processor be almost toast? and if not now, what would the effect be of it running at such temps for an hour?

Sounds like you need to apply some TIM (Thermal Interface Material) or paste. Every heatsink has some TIM on it, if you remove the HSF, which you only should do if you have TIM on hand, is to clean the HS and the CPU with denatured alcohol (the more pure the better) and then reapply the TIM and reseat the HS.

The CPU should throttle when it gets too hot to protect the CPU itself so you may be fine... but you need to find some TIM, you can buy it at most good computer stores.
