Hp Spectre x360 black screen and wont turn off

[calumvc]

I have an hp spectre that I occasionally use with a (hp) dock into two monitors, one with displayport and one with hmdi. While using just hdmi earlier I turned the laptop off, and turned it on later. Laptop came up with a winpeshl.exe window and a blue back screen. I closed the window because it was bugging out, now the computer screen is completely black. The computer is on and running, power button light signifies on and I can hear it, however it wont turn off, or display anything whatsoever. Ive held the power button down for 5, 15, 30 seconds whatever, and it wont do anything. Earlier on in the blackscreen I pressed the button to activate the keyboard backlights and it worked, but now it doesn’t. Laptop is less than 2 years old
