Got a annoying problem. When I've shutdown the computer and pressed On / Off it's all ok. But after just a few min it starts by itself again.

What can the problem be?

could be a virus like sasser that has this affect. or could be heat related, or possible a driver that is not compatable with your OS.. XP is known for driver conflicts.

run an online scan and check that you have all the m/soft critical patches.

regards

Okey.....I'll try see what I can come up with.
I'll be back later to tell what happend.
