I can load Knoppix (linus on a bootable disk) and this runns ok. I have not added any hardware, I think the fans are all working. I only got this error message after I tried to repair XP. I had a problem with Internet Explorer which took 100% of the CPU time (according to task manager). Shopuld I re-install XP from scratch and loose all my other progs on the machine?
i would endaavour a little more, the fact that you say linux runs off a bootable disk suggests that everything but the hard drive is fine. Can you check this in another machine? or can you you get a repair screen using your xp disk?
