After I shut my computer off, when I turned it back on it wouldnt give a signal to the monitor and only the mouse would turn on, not the keyboard. The pc would shut off after a few minutes when I turned it on. I had to wait hours and try again and eventually it would all work again. This happend twice I think. But the 3rd time i couldnt get it to work. I unplugged the power and held down the power button, took out the ram and put it back in. All cables I can see inside the PC seem to be in correctly. And when I tried turning it back on after doing those things the computer stayed on but still no signal to the monitor and the keyboard isnt working. I can't figure out what the keyboard and monitor have in common and why its just them not working. I tried switching which usbs the mouse and keyboard are plugged into but still only the mouse works. I know the USB port is giving power to both the mouse and keyboard, and I know that the keyboard isnt broken. What is happening!?!?! Please help me. Thank you.

@HelpPcNotWorkin,

 

Welcome to the HP Support Community!

 

In order that I may provide you with an accurate solution, I will need a few more details.

  • When was the last time the computer was working fine?
  • Are you getting any display or an error on the computer?
  • Have you made any software or hardware changes on the computer?

While you respond to that, I recommend follow the steps in the below article and check if it helps.
