And while yer at it, clean the old gunk off the mating surface of the heat sink/CPU and apply a dab of new cpu grease (thermal paste).
Unless yer a total mechanical putz, it couldn't hurt and a small tube of quality paste will only set ya back about $5.
ps: office 07 sucks beyond description .. cheers

Something changed this on my machine.
I’m up and running now.
I’m going to attempt to run this thing until it crashes.
