Windows XP keeps restarting

November 2015

Microsoft's Windows XP operating system is used on personal computers including laptops, business and home desktops and media centres. You may come across problems now and again despite regularly updating your system. Suppose you have updated your Windows XP copy and yet it keeps restarting when you turn on your system: in this case you will need to restart your computer in safe mode and locate the registry key, modify the value data box and restart it again. The other method is to insert the Windows XP CD in your CD drive and restart your system. Press R to start recovery console, select the installation you want to access and follow the setup process.

Windows XP keeps restarting


My Windows XP Notebook keeps restarting. When I turn it on, before I can type my password to log into my account, the screen turns blue for a second and says : A fatal error has occured. Windows has been shut down to protect your files. Then, it restarts and repeats the entire process.

I tried going into Safe mode when Windows starts up but it still restarts and I can't log in. I have also tried Last Known Good Configuration, Safe mode with Networking, Safe mode with Command Prompt, Start Windows Normally and Reboot but it still does not work.

Please advise me on what to do next: should I try "Disable auto-restart when system fails" ?
