Unauthorised shutdowns

[Cranfield]

A friends computer keeps shutting down, for no apparent reason.

He has done a Norton sweep and found nothing, AdAware etc., with the same results.

This is a message he gets;

"SYSTEM SHUTDOWN

C:WINNTSYSTEM32LSASS.EXE

TERMINATED UNEXPECTEDLY"

 

Any ideas, please ?

Before going to far check the basics,

 

Is the CPU fan working ok.....has it slowed down due to wear or dust. Is it seated ok with a dollop of paste. Have the fins on the heatsink clogged up with dust.......especially if it located near a door or window (does not infer lack of housework,it's an entry point of dust)

Has he bought any new memory.....that was a fault I had. Was told memory either works or it does not......not true.

If it is none of these i'm sure the more tech help will be supplied.
