If you have forgotten your BIOS or Hard Drive Password for this model, there is a master code that you can obtain from Dell Support. Simply call, Email, or use Online Chat from http://support.dell.com and give them your Service Tag, and they can help you out from there. If it is a Windows profile password you have forgotton, try accessing the Administrator account from Safe Mode (Press F8 at startup), and remove the password for the user account from Control Panel, User Accounts.

SOURCE: I lost all password for
Lots of sites say to move the PSWD jumper (on the motherboard) from pins 1&2 to pins 3&4, or something like that. However on my Optiplex 360 I found that the PSWD jumper had only 2 pins. By trial and error I found that removing the jumper from these two pins while the system was off allowed me to boot the system with BIOS password disabled. I was then able to change BIOS settings (and install Linux - yeah!!).

Dell has all of their computer's drivers online, in their Support section. You will need to input the Service Tag of the computer to find the ones for you.
