You remove the jumper from the motherboard and start up the machine, you can then clear the password in the BIOS settings.  Hope this helps!

Please see that the connectors on the PC, check if there is loose connect on the board. Also if the bios battery is low on voltage- check with a multimeter.
Finally the memory card can also have a loose connection on the slot, remove and reset or try with another card.

I'm trying to reset my system to the factory reset setting for the Dell OptiPlex? GX620

Bios or windows? If bios, go into bios by pressing delete key at computer boot up. Then go to last tab and look for load default settings. If you are referring to your operating system. Use your recovery disk or partition and reinstall the operating system. Or you can try Control Panel\Backup and Restore Center
