Vista Suddenly Locked

Hello.
I have on my PC Vista Ultimate 32.
Last night i saw a movie near my PC and left it open (most of the time i locked it when not in use), when suddenly right in front of my eyes - the PC locked him self!
It was like i locked it myself - but alone!
So, i run AVG scan, W Defender scan and another anti-spy program scan - nothing.
My UAC is on all the time. My Fire Wall is on all the time.
I am the only user on this PC, and no one know my password.
I check in the Event Viewer and there was no unusual activity. the locked activity was mentioned but in the normal way, as if I was the one that did it.

So - what can it be???
Is it Vista failure?
Or maybe someone broke into my PC?

Hello roeelo.

Do you have the screen saver set to display the welcome screen?

Hello, mine will do the same thing for protective reasons, not because vista is broke or someone has got into my pc, but because every time you leave your laptop or desktop alone and you have a password set for it, it will usually lock itself right before the screen saver comes up, or it has not been used for some time.

Sorry, i forgot to mention the most important fact - i don't have screen saver, and the Power Settings is set to 3 hours.
So it does not have any thing with screen saver.
Last night i leave my PC for 1.5 hours - and it didn't happened.
so whet do you think?
