Mi pc reboots by itself, sometimes it opens programs by itself as well. Why could that be?

Answer 1

It sounds like something is not Kosher there!
Is this a sudden problem? Did you notice that a Microsoft service pack was being installed just before this all happened? Any other changes such as a new program you installed?
The most obvious thing to be concerned about, when this type of thing happens is: are you virused or trojaned?
Have you scanned with any software since this started? Such as Panda Soft or Norton or Spybot Search and Destroy? Is your anti-virus program functioning and updating? Do you have one?
You can do online scans at TrendMicro, PandaSoftware.com. Get yourself a copy installed of Spybot Search and Destroy (free) and make sure when you instal it that you select the tiny check marks on the main window for "TEATIMER"...this protects your computer 24/7 from anything trying to instal or use your computer.
