How do i fix a computer laptop rebooting automatically before its desktop display.

In case of infinite reboot
- Restart your computer

- Tap "F8" key immediately: you will reach a list of boot options
- Select "Disable automatic restart on system failure
- Press "Enter" and wait for your PC to boot.

blue screen in XP is usually due to hardware issues. Did you add or change hardware? By now, probably your only solution is to repair windows XP by putting in the XP setup disk and get to repair. If you do the install, it will format your hard drive and you will lose your programs and files.

hi Andrew.
"Upon the 'Preparing automatic repair' window, press-and-hold Power button 3 times to forcefully shut down the machine. The system will enter boot repair page after 2-3 times of reboot, choose Troubleshoot, then go on to Refresh PC or Reset PC."

What Diagnostics? Is this before the system completes the boot process or is this after windows has booted up and the desktop with icons appears?

You have two options to remedy the problem. You really need to access the computer in Safe Mode and view the System Logs to determine the offending piece of hardware or software or virus. But your real question is how to stop the reboot. Use the F8 Key during boot. Right after you turn the computer on, start hitting the F8 Key. The Windows Boot MEnu will appear. at this point you can do one of two things to try to fix the problem. You can enter the computer in Safe Mode which load Windows with only the minimal necessary hardware and software drivers.If you want to see the error message, choose option 8 which tells the computer not to automatically restart after an error. This will enable you to determine the error message on the screen and prevent the system from just going through an endless loop of starting, erroring-out and restarting..

F8 (during boot) Holding F8 when booting displays the Windows Boot Menu
SHIFT (during boot) Holding SHIFT down when booting forces Windows into Safe Mode

Let me know if I can be of any other assistance to you

Depends on how it's used.

1) "Boot your computer up", may refer to simply turning the computer on.

2) "Reboot your computer", may refer to turning the computer completely off, waiting 20 seconds, then turning the computer back on.

3) The Windows operating system has a Boot Record, which is located on a Boot Sector on one of the Platters in the Harddrive.
These are the basic Windows files.

The computer can also be booted off of another source than the Harddrive.
It can be booted off of a Floppy Drive disk, USB thumb drive, CD disk, or from the internet, to name a few sources.

Therefore it can also mean to reboot off of one of the above sources, instead of the Harddrive.
