CPU fan working OK isn't that relevant, since it only tests one
factor. Check the CPU temperature in the BIOS. That requires many
factors to be OK. It requires the pad/paste to be OK, the heatsink to
be installed OK, the heatsink the right heatsink.
That is the test. See if it keeps climbing and climbing beyond 55 or
up to 60. Leave it on for 2 hours, reset, go to the BIOS, check the
temperature.

it could be software.
If you think it's worth bothering to keep trying to diagnose it, then
try a b and c. Otherwise, skip straight to d.

a)Try a different browser.

b)Try formatting and reinstalling windows or
Try making the partition smaller (partition magic), creating a new
partition,
installing windows on that and seeing how that goes.

c)Try disconnecting from the internet - unplug the cable, and see if
it still crashes.

If all that fails, it may be the hard drive

d) Try a different hard drive, reinstall windows. if it still crashes,
then use a different browser, if it still crashes the disconnect from
the net. If it still crashes then it's probably the motherboard.
If it is a Ps2 problem, then change to a USB mouse and keyboard
(though those are more likely to have problems)
If a change of HDD and reinstalling everything and using a different
browser and disconnecting from the net don't stop it crashing, then
it's the motherboard, and it may be a cheap motherboard.
