Hi. I have a hp pavilion all-in one 24-xa1007na running windows 10 with the screen broken so it's plugged in an external monitor (HDMI) . My son updated the graphic card, AMD Radeon™ Vega 8 Graphics. I don't know exactly what happened but when the computer boots, the lights at the back are on and it makes reading noises like it's working but monitor is black. Of course the broken screen is useless but I can see 'repair' on it. I've dismantled the whole computer, clean connections, adjust cables, changed RAM slots, plugged another monitor. Nothing is working. I can't enter into the Bios to attempt a recovery system from USB because its primary boot is the HDD. I'd there something else I can do, please? Thanks
