Hi bugmento,
If Windows XP is the only operating system installed on your computer, booting into Safe Mode with these instructions.
* If the computer is running, shut down Windows, and then turn off the power
* Wait 30 seconds, and then turn the computer on.
* Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
* Ensure that the Safe mode option is selected.
* Press Enter. The computer then begins to start in Safe mode.
* When you are finished with all troubleshooting, close all programs and restart the computer as you normally would.
Best regards,
