BleepingComputer.com: Windows keeps shutting down during long processes

This is the second time that, without warning, the screen suddenly faded to black before the computer immediately shut down, while i was in the middle of a drive backup to external drive using Paragon (Paragon SUCKS by the way).

The first time I was away from the computer, the second I was watching a movie. Both times automatic shutdown after backup was, by default, turned off. Also the first time when I tried to turn it back on after the second shut down, the computer was powered only for a second before turning off again.

This has been an obnoxious issue a while ago before, occurring frequently when I was trying to, as I can remember, import a bunch of tapes from my camcorder.

I'm going to initiate another backup after posting this.

Thanks for any help!

Does the Event Viewer give any clues

Worked this time :/

I'll check that out, thanks. I did forget to mention that the first time I turned it back on, after getting to my desktop I got a "windows recovered from an unexpected shutdown" dialogue...
