I dont know which compaq system you had, but generally there are two ways to reset bios
1. short the bios reset jumper near battery on motherboard for a while and place it back, it will reset the bios. 2. take out the battery from motherboard for some time and put it back to motherboard it will also reset the bios
if there is no password problem then just load bios default from the bios menu.

Reboot the computer and hit f2 when you see the logo come up and this will take you into the bios setup. Arrow over the the tab that says exit and arrow down to the selection that says load setup defaults and exit. This will reset the BIOS to the factory defaults.

Which operating system ?
The Compaq Presario CMOS password is an administrative security measure built into the firmware of a Compaq computer.

This password is stored in the motherboard's BIOS (Basic Input Output System) and provides for hardware-level security.

This password may be accidentally set or forgotten over time and must be reset in order to boot the computing system.

Disconnect the Compaq computer from any electrical sources and remove the side access panel from its case.

This may require the removal of one or more thumbscrews on the rear of the computer case.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules

Locate the CMOS battery.

This battery is a round button-type battery located in the bottom-right corner of the Compaq Presario motherboard.

Grip the battery by its edges and pull it straight away from the motherboard to remove it.


Press and hold the power button on the case for ten seconds to remove any remaining electrical current from the computer.

This removes the CMOS settings and returns it to the default state of having no password set.

Replace the CMOS battery.


Replace the computer's side access panel and re-establish any previously severed electrical connections.

Try using your windows cd to boot up the computer and if that does not work then you may need to reset the bios. Inside the case if it is desktop there is a way to reset the the bios. There is a jumper that needs to be switch then switched back that will reset the bios. If this does not work may need to get a new hard drive. The MBR ( Master Boot Record) may have been corrupted.

I know some methods to reset bios password.

You may be able to purchase a system disk from Compaq, otherwise, try any generic XP disk. It won't have any Compaq drivers, but at least you can reformat the C: drive and get XP on it.
