Select and save your BIOS default settings
On first power up of the PC, repeatedly press the delete key on your keyboard until the PC enters the BIOS mode. This only works with a wired keyboard so if you use a wireless one, you may need to swap for a wired keyboard to undertake the BIOS setting changes.
Once in the BIOS, press the F7 key to load BIOS default settings. Press F10 to save and exit.
