    ON Initial Start up I get a black screen on the monitor that say "Enter CURRENT Passwod" you only have three chances to enter it, and it is a maximum of 8 letters or characters.

Hit Ctrl + Alt + Del twice at the welcome screen, type Administrator for username, and leave the password blank. Works about 80% of the time for me, almost nobody sets the Administrator password.

    Oh, that's the BIOS password. You have to reset the CMOS settings on the motherboard. You do this by moving a jumper on the main circuit board. It's a little plastic cap that shorts out 2 pins.

    In a tower case this will be to the right of the 3rd white PCI slot from the bottom of the case. Turn the machne off. Move the jumper to the pair of pins nearest the PCI slot. Turn the machine on.

    You should be taken to the BIOS setup. Select the option to clear all passwords and pick "yes". Then (this is important) select the option to exit the BIOS and save your work. Then you should get a prompt telling you to turn the machine off and restore the jumper to its normal position.

    Once you do that, you should be able to get in.

Dell 4100 Dimension Desktop, Default Password

Do you have the software disks that came with the system? If it was given to you and you arent really sure of whats on it (viruses included), its worth reformatting.

If you have the disks, you can put the operating system disk into the computer and have it boot off of that.

Log in the default administrator account.

When the black command window appears type: control userpasswords2

Click on the user account you wish to change, then click 'reset password'

Lost password for Dell Dimension 3000.

If you have all of your important documents on a separate hard drive then you can reset the computer main frame and then you can recreate a new password! and if that doesn't work then you can always have a computer tech. take a look at it! Infact i'll give you the number to a guy who live's in S.C. His name is Dwight Welsh but you can just call him mister Welsh. So any ways his cellphone number is (910) 494-7467.
