The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

Boot from the CD

When the "Welcome to Setup" screen appears, press R to start the Recovery Console.

If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console.

When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.

Let that run through and then restart the machine after it finishes.

If that doesn't fix it, run the Windows XP Repair Installation. You can find a walkthrough here - click here
