When trying to troubleshoot a problem with Windows, or when trying to clean up after a virus or spyware, it is sometimes necessary to run Windows in safe mode.
Safe mode is a special operating mode in which only the bare essentials of Windows are run. No networking software is used, so you cannot connect to the Internet or another computer. No inessential services, including anti-virus or personal firewall services, are started, and no drivers for inessential devices are loaded, avoiding the possibility of conflicts. Only a basic 640 x 480 graphics display mode is supported, so your graphics card drivers are not loaded, making it possible to solve display-related problems. If something doesn't work as expected, and you suspect that the problem might be caused by a conflict with something else, try it in safe mode.
Method 1
To start Windows XP in safe mode, start the System Configuration Utility (click Start, Run, type msconfig and press Enter).
Select the BOOT.INI tab.
Tick the check box marked /SAFEBOOT and click OK.

Restart the computer when prompted, and it will restart in safe mode.
Before closing down or restarting from safe mode, repeat these steps and untick the box marked /SAFEBOOT.
Method 2
If you are unable to start Windows normally, then you will be unable to access the System Configuration Utility to use Method 1.
In this case, switch on the computer and hold down the F8 key while it is booting.
When the boot menu appears, select Safe mode.
two comments:
I don't need to but, I want the option when needed. Can't boot into safe mode using F8 or F5, tried many times system just boots normal. I can boot safe mode if I use msconfig. do you think it's a bios setting issue?

Do you use a USB keyboard? If so, F8 or F5 won't work since USB is registered only after all XP drivers load. In this case you will have to use msconfig.
