Hi Geeksters!,

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..

running:

Under the bonnet..
Win XP home ed SP2
512 MB RAM
80.0 GB HD
RADEON 9700 PRO display Adapter.
AMD Athlon 2600+

Norton06
spybot
Ad-Aware SE personal
clean up
spyware blaster
peer guardian
win patrol


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

Thanks in advance

OS.

You appear to have an overheating issue.

When did you last clean your Computer
inside?

Check your power supply, too. A bad PSU will cause an almost identical problem.

Thanks for the advice,
As it stands I installed a new fan (there was no actual fan,apart from the psu one that was connected to the outside of the box..built it myself and I guess I forgot to add them...)and got busy with my can of air and some cotton buds that I ended up using like chopsticks on the fan blades, well there was PLENTY of dust...the result is that everything is running again as normal :blink:

Thanks,
yet again the Geeks triumph :whistling:

Cheers

Os.
