Hi.

In the last couple days my computer even shuts down shortly after i start it or it freezes. After a few boot ups and restarts it works fine untill i shut it down and boot up again.
I havent changed anything software nor hardware.

It doesn't make any sound just shuts down. It is the same temperature as it have been for 1 year.
