The first thing I would do is check to see if all the cooling fans are 
spinning full speed or at all.  If they are, check that your heat syncs 
all securely stuck to their chips.  If they wiggle at all, you'll need 
to pull them off and  Clean off all the old heat sync compound, reapply 
new stuff and put it back together.

I just recently had a computer that was doing weird things.  Turned out 
that one of the 4 clips that held the CPU heatsync/fan down had come 
loose and was causing a gap between the heat sync and CPU.  I pulled it 
off, cleaned it up and stuck it back down and it's been fine ever since.
