Computer is unexpectedly shutting down

  Yimbo 11:28 29 Aug 2012

I'm putting together a video presentation, but during the compiling process, my computer suddenly shuts down. It goes on to restart, but I have lost the progress thus far made with the presentation, and I have to begin all over again. Then, while doing that, once more everything shuts down, and I'm back to square one.

I was doing similar work yesterday with no problems.

I'm using XP Home (SP3).

Any ideas as to what's going on?

WE need to see if there is an error message or if its shutting down through overheat,

Overheat check all grills are clear and fans running OK, take cover off and see how dirty its is inside especially round the cpu heat-sink and fan.

Error message

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"

Thanks Fruit Bat/\O/\ - - I think it's probably over-heating, as you've suggested. I looked at the front grill of my case and there was a lot of dust colllected, which surely was blocking things up! I've taken the Vacuum to the outside - but not ventured to the inside, not wanting to damage something! I'll see if my cleaning thus far has made a difference.

There was no "error message" or blue screen - just an immediate shut-down followed by a normal restart.

Thanks again for your help! I'll let you know how I get on!

You will need to venture in as I can guarantee you will have plenty of dust inside particularly round the CPU fan and the graphics card. A soft paint brush and the hoover will work wonders and you are not going to hurt/damage anything.

You will need to venture in - - -

Thanks Chronus - - I've had the front fascia panel off - but then I'm confronted by an aluminium plate affixed by several screws, and a couple of quite large black objects (no idea what theese are) which look as though they're just plugged in. Would it be OK to remove these and the screwed on plate? Is this how you get access to the fan etc - - or are the side panels also removable?

I really don't want to make matters worse by some ham-fisted action!

Put the front back on

to remove the side panel (left as you face it)remove the three or four screws at the rear and slide the panel backward.

Take the side panel off.... not the front

Lots of great advice above, but if all else fails it could well be your Power Supply Unit. I had similar problems a few months ago..... after hours / days & weeks of frustration, i found somewhere on the WWW to try PSU..... and sure thing that was the problem, running as sweet as a nut now. :)
