Try entry to bios recovery. Step 1. Power off your computer and make sure that the AC adapter is connected to the power source. Step 2. Press and hold the Win + B keys and then press the Power button at the same time. Step 3. Wait for 2 or 3 seconds, continue to press and hold the Win + B keys but release the Power button. If smooth, the HP BIOS Update screen will be displayed after a series of beeps. If this will not help I guess that you need programming bios chip outside motherboard
