Windows XP keeps on restarting

My desktop computer keeps restarting and I don't know why. Can somebody please help me?

I have tried removing the plug, cleaning the fan and holding the power button for ten seconds, but nothing worked!

I use Windows XP.

It goes till the Windows XP logo with the loading bar and then it shutsdown and do it again. I tried leaving it the whole day, but it still didn't work.

It instantly reboots.

I tried booting into safe mode, but it just did the same.

Ok now I get the following message:

We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this.

If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked.

If a previous startup attempt was interupted due to a power failure or because the Power or Reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows Normally.

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Last Known Good Configuration (your most recent settings that worked)
Start Windows Normally

Use the up and down arrow keys to move the highlight to your choice.

When you say your computer keeps restarting, do you mean that Windows is doing a clean shutdown and reboot? Or do you mean that your computer instantly reboots? Could you also provide details on what you are doing when this happens? Does this happen after a specified period of time?

Have a look at the System event log. Click on Start > Click on 'Run' and type 'eventvwr' (without quotes) and press Enter. On the left hand side of the window, select System. Check for any Warnings/Errors that happened around the time the computer last rebooted itself.

Thanks

Do you mean that your computer keeps rebooting or it keeps turning on automaticly after you shut down and then automaticly shutting down over and over again?

Whatever the case, press F8 and select safe mode with command prompt then use the reinstallition command. It should be fine after that. Ask a technition of what the command is since I forgotted that command.
