Exclamation Intel Quad Core Q9400 Too HOT!

I'm new to these forums, but thanks in advance for any advice.

So, i've had my computer for roughly 2 years now, and haven't had too many problems with it. But one thing that has come up recently is my computer will randomly turn off, and stay off. I can't power it back on without taking the powerplug out, waiting 10 minutes, putting it back in, and starting a few moments after that. And even then, when i try to use my computer, it will run ok, but freeze up a lot, and slow down. Then anywhere between 10 minutes and 3 days after, my computer will turn off again, and i'll have to redo the whole thing. Sometimes i have to do it multiple times for it to stay on for a decent amount of time.

I've noticed now that my CPU is running at roughly 60-75C on a medium load.
Is this too hot? I've taken the Heat Sink out, cleaned it and all that. But still nothing.

Is there anything i can do to try and cool it down?

When you cleaned the heat sink, did you put new thermal paste on? I'd start with that. Put a dab on the center of the processor and let the heat sink spread it out, otherwise you'll create air bubbles and that'll for sure burn up the processor.

Under a medium load I would say that's too high. Mine sits at around 60 under a full load (half an hour of Bad Company 2)
I can't explain what else is happening, though.

We need to know what thermal paste your using and if you applied a new one also.
