I am having an issue where my computer will just shut down unexpectedly.
when not in use I have the power supply switched off (at the powerpoint).
when I start up everything is fine but in about 3 minutes the system shuts down...no beep ...nothing..I leave the power on and reboot and usually everything is fine...there are no error messages or warnings...or "computer encountered stuff.." every thing will work well, then if I try certain things, for instance, I will run spybot and at about 2/3rds or 3/4s into the run the same thing happens. but all other programs run fine....I am at a loss..
Under the bonnet..
Win XP home ed SP2
512 MB RAM
80.0 GB HD
RADEON 9700 PRO display Adapter.
AMD Athlon 2600+

Any kind of help or guidance would be very much appreceiated.
Thanks in advance
