Hi There,

I am new on the site, but have a problem with my small office network computers (XP small business Edition) (+-15 computers).



Certain computers (not all) continually shut themselves down, with no warning. Its almost as though someone disconnects the power and then turns on the PC. Some computers do this up to 20 times a day, whilst others do it every few days. The Server itself, used to shut itself down as well, but now seems to have stopped?

I have NOD32 on all the computers, and have also run Super-Anti spyware- but to no avail. One computer in particular, will shut down when the the antiviruses are scanning- so have run the scans in safe mode (This is one of the pc's that shut down up to 20 times a day). In safe mode- the computer did not shut down the entire day.

Any help with this will be greatly accepted and appreciated- Many Thanks for any help in advance!!

Many Thanks

From your description, this does not sound like a malware issue
Are you getting any error messages when they shut down or do they just shut off to a black screen

Two likely suspects are bad power in the building. Which you would need an electrician to inspect
Another one would be overheating
How old are the computers and have you ever had the sides off?
Dust and lint build up around the CPU heatsink and fan and will do exactly what you describe

Pay particular attention to step C: Heat sink and Fan
