Question about Dell Dimension 3100 PC Desktop
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.

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.

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.

Tips for a great answer:
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.
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.
