Hi, Lets outrule malware. I think its not that.
My desktop pc randomly shuts itself off. If i manually restart it, It will start and maybe finish loading up the programs but then shut off again at any given time. Its been doing this on and off for months now.

I was reading another post about looking in the "event log" or something to see what error it shows. Or is there another way to tell. Maybe a file is missing or corupted. Of course it could be a mechanical error as well.

Windows XP Home edition, sp2-Dell dimension desktop-Internet explorer 7-up to date on virus definitions and security tools.

Thanks in advance

In Windows XP, the default setting is for the computer to reboot automatically when a fatal error occurs. An alternative is to turn off the automatic reboot feature so you can actually see the error code/STOP Message (which is also known as the Blue Screen Of Death (BSOD)).

To change the recovery settings and Disable Automatic Rebooting, right-click on My Computer and select Properties > Advanced tab. Under "Startup and Recovery", click on the "Settings" button and go to "System failure". Make sure that "Write an event to the system log" is checked and that "Automatically restart" is unchecked. Click "OK" and reboot for the changes to take effect.

This will not cure your problem but instead of crashing and restarting you will get a blue diagnostic screen with information displayed that will allow you to better trace your problem. Next time your computer crashes copy down the entire error message (including all the numbers) and post it back here.
The power of accurate observation is commonly called cynicism by those who haven't got it.

Does the computer completely shuts itself off or does it reboot? If you have a spare power supply you can try replacing that and see if the problem disappears.

Hi,
Dr Manhattan= THe computer always completely shuts itself off. It will not reboot on its own; i must manually restart it. I dont have an extra power supply that i can switch over.

Budapest= As far as what you suggested,

To change the recovery settings and Disable Automatic Rebooting,

........it was already UNCHECKED. SO I did not have to do anything in that area.
Still, the pc shuts off without warning and it will not restart unless I push the power button back on again. SO, how can I see any logs if the pc doesnt stay on. THe first boot up this morning stayed on for 30 minutes. other attemps are like 3-5 minutes if that.

Very few times this has happend: after me restarting the pc, I have seen that the black screen with white letters shows- THis screen asks you if you want to start windows normally or in safe mode or last known configuration, etc. and it says lots of other things. It doesnt matter which one I pick, the pc will still turn off at any given time.

ANything else I can try if i happen to have a longer pc-on session soon??
Thank you for your time

so in other words, it randomly shuts off without any error warning of any sort? That would be likely overheating, if that's the case

Garmanma & others,
Yes, it randomly has been shutting itself off. No blue screen of death. No warning that it is gonna shut off. Today, it managed to stay on for like 40 minutes. Then it shut off. I restarted it a few times and it stays on for 3 minutes or a bit more.
As stated earlier, I dont get error messages or anything. YOu say overheating? or like Dr _Manhattan said maybe I can switch a power supply to test it.

I have the exact same Dell at home (same year, same everything pretty much) that barely gets used. How much work would i be looking at if I took power supply out of that Dell and put it in the "bad" Dell. I have NO experience whatso ever doing mechanical things to pc's. any easy to read tips for a novice?

Lets suppose I do need a pwer source. Are they pretty universal?
thanks for all your answers

Cleaning PC interior:

http://www.bleepingcomputer.com/tutorials/...l118.html


Power supply
The purpose of this procedure is to bypass the motherboard to test the PSU.

Caution:
This procedure will involve working with live 12VDC electrical potentials which if handled improperly may lead to electrical shock. Proper precautions should also be taken to prevent electrostatic discharges (ESDs) within the case of the computer. For safety purposes please follow the instructions step by step.

First, shutdown your computer. Then unplug the power cable going into your computer.

Once you have opened the case, touch the metal of the case to discharge any static electricity.

The connector of the PSU which connects to the motherboard is readily recognizable by the number of wires in the bundle. To disconnect it you will need to press on the plastic clip to disengage it and then pull the connector up and away from the motherboard. Please take notice of the location of the locking tab and the notch on the socket of the motherboard, this will only connect one way as it is keyed. This wire bundle will have a memory of the way it has been installed and will want to bend back that direction, you may have to play around with it to find a position that the connector will stay in the same position while you run the test.
