SOURCE: Bios default password

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.

SOURCE: sound for dell optiplex 755

You can download the drivers from Dell WEB site, the support download page. Make sure you select your model laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop. This will open the page where the specific drivers for your model laptop are located. Also make sure you select the Windows XP or Vista version of the driver for your Windows operating system.

Generally an indication that the Hard Drive isn't detected
Things to check, go to BIOS F2, reset defaults and reboot, see if the HDD is seen. If it is, the battery on the motherboard is likely dead and needs replacement (Watch battery at Walmart, 3 dollars)
If the HDD doesn't detect after resetting the BIOS, then most likely a Hard Drive failure
