Usually, thats a sign of cpu overheating.  At 18 months, if the cpu
fan/heat sink hasn't been blown out by an air hose, its so packed full
of dust bunnies that no amount of rpms can force any air thru the cpu's 
heat
sink fins.

If its been doing it for a while, I expect the grease between the
bottom of the heat sink and the top pf the cpu has also dried out and
is no longer as effective at moving the heat from the cpu into the
heat sink itself.  So its probably a good idea to do a shut down,
remove the heat sink/fan combo, clean it all up and put a dab of new
grease under the heat sink before ytou clip it back on.  I'm partial
to a fancy bit of stuff called artic silver, which when fresh, is
pretty darned good at moving the heat.

If you aren't comfortable doing all that, find someone who is.
