Marwan_vaqub,
Dell does not supply bios passwords for Desktop systems. You would have to change the motherboard jumpers to clear the bios password. For help to clear the password please contact Dell Support for system ownership verification and they will then help you resolve clearing bios password.

Thank You,

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: Upgraded Dell Dimension 3100 memory to 2 Gigs - Windows XP fails

Did you add the two sticks with the 512 or remove the 512 and add the two 1gb sticks? Try booting the machine with ONLY the 1gb sticks in.

Your machine supports 1gb modules but they can't be higher than 533MHz. Check that the memory you purchased was either PC3200 (400MHz) or PC4200 (533MHz) and is 1.8v. If you post the part number off of one of the modules I can look it up for you.

    Turn on your computer. If your computer is already on then reboot it. You need to see the initial display screen to get into the BIOS.

  • 2

    Press the "F2" key when you see the initial screen displaying the BIOS provider information. If using the Optiplex and Dimension models, press the "DEL" key instead of the "F2" key.

    Enter password if required. When finished in the BIOS be sure to save your changes. For changes to take place you must reboot the computer.

    Your "friend' probably put a BIOS password on your computer. Find and disconnect or remove your BIOS battery on the mother board. You may be able to slip a business card under the contact on the top effectively removing the power from the BIOS. Let it stay disconnected for 5 minutes. Reinstall and reboot.

    If this doesn't fix it, you will probably have to get professional help at your computer dealer or repair shop.

    Lesson learned: Don't lend your computer or your spouse to your friend.

    try going into your BIOS and changing the boot sequence, it may be set to boot from floppy instead of harddrive. or you could just reinstall windows, but that sucks cuz then you lose all your data and programs. and not to be rude, but you shouldnt have bought a dell, they are full of problems.

    Bios Error Message


    With the system off, open the side cover and re-seat the RAM. You may have one module that is bad.
    Second, press F2 as soon as you see the Dell screen and see if you can get into the BIOS setup. Post back with the results please.
    Good luck!
