Hi @Driesez , please check if the cables and the power supply are properly connected and retry. If it does not work, and if possible, try using different cables. Afterwards, you can try resetting the PC mains adapter by: (a) Disconnect the PC from the power supply (b) Then press and hold the main switch on the front for 10 seconds. (c) Wait another 5 seconds, reconnect the power supply and restart the PC Please let us know if it worked Regards, Gehringer
