1. Take it apart and make sure that the heatsink is clean and the fans are spinning freely.
I agree with Nihil. I personally wont start trouble shooting a problem such as yours until all dust has been cleared from inside the chassis. In almost all cases, the removal of all dust will fix heating issues.

Try removing the dust. Letting your PC cool down for a bit, then boot it up and see what happens.

If this fails, you may want to run a diagnostic tool. A good one I use is SuperDiag from Eurosoft.
