Why does a PC turn itself off

[Mouse Potato]

Hi,

I havea prob with Pc. It loads up fine, no probs then all a sudden decides it has had enough, logs itself off, closes all apps and shuts down. Checked for virus's etc. but none there with newest Defs.

So why is this happening? Anyone?

new build, new parts or something? could be PSU, could be something with advanced power management or bios setting, is it shutting of or restarting... go into event viewer check there also goto startup and recovery in system properties advanced tab and remove check mark from restart after system failure. Could be temp related, too. Hardware compatability problem, depends. What was the last thing you did and also list what event viewer might show around that time and if removing the restart from recovery see if you can get an error and post it here.

Did you get on the net and a box pops up and reads restarting in so many seconds?

bad psu or boot sector virus or power is set up this way in display properties

From the way that Mouse Potato described the problem, Warez's idea was the closest. There is no way that a faulty PSU could close down all apps, etc. A faulty PSU will turn a computer off instantly.

Warez's idea was something along the lines of the Sasser Worm, among others that automatically turn your computer off.

The best way to combat worms is to go to the Windows Update website and download all of the latest security patches. Plus employing a firewall will also help to keep worms out.

Actually that is what you usually call a boot sector virus. it is also a lot harder to catch with an A/V. Kaspersky labs it the only av people that specialize in cacthing those type of viruses.
