The game will not boot and shows almost no sign of life, even after a new motherboard battery and the usual clear-settings jumper (or the off-board reset switch).
Game shows no sign of booting: unplug every USB device from the computer and restart
Cause: The PC motherboard was stuck before start-up, apparently held up by the attached USB devices.
Checks
- Make sure the CPU board gets 3.3 V, 5 V and 12 V on its standard ATX power plug.
- Watch the monitor for a start-up prompt when the computer is restarted with nothing plugged into its USB ports.
Fix
- Power off, unplug all USB devices (including the dongle and the board cables) from the motherboard, and restart the computer.
- Once a start-up prompt appears on the monitor, power off, plug the USB devices back in and boot again.
Turn the game off before unplugging or reconnecting anything inside the backbox.
