I believe in coincidence :-)

It has exactly the symptoms mine had, and I'm in an airconditioned room,
filtered air, etc to 20C constantly, the laptop never leaves the desk.

SpeedFan will tell you all, it's a very useful program IMHO.

But if it isn't that, please let us know the outcome. I have a problem with
XP using loads of CPU even when locked, and I never find out what it is, but
I can see it on the SpeedFan graph and logs. When I unlock, the CPU goes
back down to 20%

Weird.
