Hy! And thenks. I am from Romania and my enghish is not good. But I try to tell you something. I work in research and developpement . My computer is not at home. Friday when I go to home this function normaly. I don't know what is happened. Normaly nobody but me have access at this computer, but manny time espacially in weekend, someone try to access this. I see that in event viewier-sistem, in computer management.

Oooh you mean it won't turn off?
Have you checked in taskmanager to see if there's anything that shouldn't be running?
Could be a virus so try a virus scan.. download free version of AVG

If nothing comes up you might as well try just holding down the power button for 5 seconds and turning it back on

Sounds like a power issue. Is the computer getting power? If not check the outket where it is plugged into to see if the out let has power. Check the circuit breakers to se if one has tripped. Also check to make sure the cord on the computer is in all the way could have come loose.
