Dell Optiplex GX110

Hi eedonatti,

I‘d suggest that you remove the CMOS battery from the computer and then start the computer without the battery and then switch off the computer after 2 minutes. Replace the battery back into the slot before restarting it again. Please refer to the link below for the steps to remove and replace the battery.

Note: You will have to setup the date and time again on the computer after performing the above steps.

Please let me know if this helps.

There is a jumper for password reset:

Disabling a Forgotten Password

If you forget your system or setup password, you cannot operate your system or change settings in System Setup until you remove the computer cover, change the password jumper setting to disable the passwords, and erase the existing passwords.

To disable a forgotten password, perform the following steps. 

CAUTION: Before you remove the computer cover, see "Safety First—For You and Your Computer."

1. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover<ADMIN NOTE: Broken link has been removed from this post by Dell>."

1. Remove the jumper plug from the PSWD jumper to disable the password feature.

Refer to "System Board Jumpers" for jumper information and to Figure 10 in "Inside Your Computer" for the location of the password jumper (labeled "PSWD") on the system board.

1. Replace the computer cover.
   
   
2. Reconnect your computer and peripherals to an electrical outlet, and then turn them on.

Booting your system with the PSWD jumper plug removed erases the existing password(s).

1. Enter System Setup, and verify that the password is disabled. Proceed to step 6 if you want to assign a new password.

NOTE: Before you assign a new system and/or setup password, you must replace the PSWD jumper plug.

There is a motherboard password that would need to be cleared by Jumper.
