How to disable HDD Bios password in dell Optiplex 990
The easy way to clear the bios password and reset bios is to take out the bios battery and start computer for about 10 seconds and then turn it back off and replace the battery. When you turn it back on you may need to go into the bios and reset everything the way you want it, and don't forget to rest the time and date.
You are welcome

are you talking about the password when you start the computer?
If it is the windows password you need to change use this linkhttp://pogostick.net/~pnh/ntpasswd to download a password changer. Read and follow the instructions.

Power on your laptop and pressing F10 to get entered in BIOS setting.
Enter your HDD password (that you previously set) and then leave the 'new' password fields empty
hit enter then save your BIOS settings.

this may or may not help, try taking out the cmos battery out (looks like a watch battery) and leave for a few minutes then replace, this will reset the bios.

maybe try taking out the cmos battery located in your case, looks like a small watch battery, that will clear bios settings and start from scratch, if there is no battery then there is a jumper sequence to do this

The BIOS default password is just blank, and it is not asked.
When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.
To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
