Suggest running a free malwareprogram such as malwarebytes or superantispyware to check for problems. If no problems show up you could do a system restore to the previous restore point. It is easy to become paranoid about event viewer. My computer runs perfectly despite numerous faults in event viewer. I now have stopped using event viewer and tend to be sceptical about its worth. There could be many reasons why your computer is shutting down but the above is a start point.

Auto-reboot disable: When Running windows and it crashes you will get a blue screen and it will automatically restart, often it will restart too fast for you to see the error message. To disable auto restart on system failure, so you can see the error message.

  1. Go to Start -> Control Panel -> System (Windows+Pause works, too)
  2. Go to Advanced
  3. Under the Startup and Recovery section, click Settings...
  4. Under System Failure un-check "Automatically restart"

This is what I would do if its a Desktop, check inside to see how may strips off memory is in it, these have tabs holding them in at each end. If more than one just try with one strip at a time, you may need to put the strip in number 1 memory slot to try it, try each strip in turn

Hi all and thanks for all the replies, i did run malwarebytes as soon as this started , full scan and it was clear, avg is clear too, but the thing is this happened yesterday morning 3 times in a row, i was frantically writing stuff down from event viewer to see if i could get to the bottom of it, but after i posted in here , the bleeding pc didnt shut down again, i was not getting blue screen or anything, i do not have a clue what what on earth was going on but it has now stopped !, i had no more problem with it yesterday and so far nothing today, so i will leave well alone and keep fingers crossed.

If desktop take the side off, take the fan off of the heatsink and clean out the dust from between the fins of the heatsink with a soft brush and vacume cleaner. It could be that it is over heating and dust also causes static.
