My friend's PC (about 3 months old) randomly switches itself off sometimes. Although this doesn't happen regularly (usually its sporadic periods where, for a month, it will be fine, and then for a day it will switch itself off a few times), it is a problem, obviousely.
He has said that there are no tell-tale signs of problems, eg. high CPU usage or temperature, broken fans, dust in the case, damage to the PC, high Hard Drive usage levels or high graphics card usage. It just seems to happen randomly.
As far as I am aware, his PC should be clean of most spyware and adware and he uses an anti-virus and firewall at all times. He uses XP Pro and has very sufficient memory / RAM / mobo / gfx for his needs.
So, any ideas please? Much appreciated! Cheers!

Sadly this can have a lot of different reasons. For example high temperature (enable warning beep in BIOS and set a temperature limit to rule this one out), broken harddrive (in this case the PC crashes more and more often until the HD stops working - good time to make a backup) or damaged RAM (there are some tools to check RAM but it is much better to get some RAM which works for sure and test it for one or two weeks). I hear from a lot of people that they get this kind of problem with XP, maybe using Win2000 (if he has one version of it lying around) will also solve this problem.
Post his full specs, including Power Supply...
It would most probably be insufficient power or bad RAM.
Does he Overclock???
Or, you could go caveman style and fiiddle about with the processor. Like tighten screws. Not too much obviously.
