How do I reset the BIOS on a Dell Optiplex back to factory settings?

1. Reboot the PC.
2. Press F2 to enter the BIOS.
3. Enter the BIOS password (if required).
4. Press ALT+F. You should hear a beep, and the menus may change slightly if you have upgraded your BIOS since the last BIOS reset.
5. Check all the BIOS settings and make sure they are right (especially the date, time and CPU hyperthreading).
6. Press ESC.
7. Select Save Changes and Reboot.

Hope this helps
