WinXP freezes within a couple of minutes after boot up. Big fan on
processor spins at 3,600 rpm and then revs up to 4,600 rpm... CPU
(Pentium D 2.66 Ghz) temp remains at 68-69C. What is causing the fan
to rev up and down so much non-stop. And if the CPU temps are normal,
why is Windows freezing?

68-69 degree's is a bit high in my opinion.
Your symptoms are consistent with the CPU running to hot and the onboard fan
control running the fan at maximum to try and cool it down.
It would also explain the 'freezing'

Open the case (power off but case still earthed) and check the CPU heat sink
is not blocked up with dust.
If it is clean the dust out with a suitable brush & post results.

Best
Paul.
