Laptop won't shut down

[amund_nor]

Hey, 17 yr PC-geek here. Not really too good, but know enough...
Well here's the deal -my Acer Aspire won't shut down.

Whether i put it in sleep, rest or shut down, it goes through the whole process all the way to completely off. Then by some unwanted miracle, it starts up again after a few seconds, just like the TV's in The Ring.

I have even made a new clean install of windows now, format and everything, and now with no programs installed (except for windows, ofc..) it's the exact same problem.

Can anyone please help me?

This was btw supposed to be a question-topic, not a discussion, dammit
(says im not allowed to edit it)
btw, it works to hold down the power-button for a few seconds, but afaik that's not healthy for the PC?
