Hi @Adrarnos,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Perform a hard reset

If your computer suddenly fails to boot properly, perform a hard reset (power reset).

For detailed instructions on resetting your computer, see HP PCs - How to Power Reset Your Computer.

1. Turn off the computer.
2. Disconnect the AC adapter.
3. Remove any discs from the disc drive.
4. Remove memory cards from the card reader slot.
5. Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.
6. With the AC adapter unplugged, press and hold the power button for approximately 15 seconds.
7. Reconnect the AC adapter, and then turn on the computer.

NOTE: If an error message is displayed, see Troubleshooting Error Messages on a Black Screen During Startup or Boot.

Otherwise, continue with the troubleshooting procedures in this document.
