Hi guys, My mate sold his graphic card and is waiting for his new one to come so thought to use his onboard graphics but no display b650 ryzen 7 7800x3d, he's tried removing the bios battery and unplugging his mains and kept the power button down to drain any power residew but still nothing on screen, thanks guys
It shouldn't make a difference, but there is a UEFI reset button the rear IO plate. Pull the mains power, leave it 30 seconds, then press and hold the button for 3 seconds. Then try booting up again.
