I have spent hours trying to resolve this issue and thought I had but it is now happening intermittently. When booting up, the HP logo comes on and then the screen goes black with NO mouse cursor. The only way to get the PC to boot is to press the power button until it goes off and then press it again and then the lock screen appears. However, this does not happen every time now. I have updated everything I can, drivers from HP, drivers from Microsoft.
