PC won't turn on

HP Recommended
Power Pavilion 580-023w
Microsoft Windows 10 (64-bit)

I bought a Pre-Built gaming pc from my friend in January. A month after I bought it, I have been having issues powering on the PC, after putting it to sleep during the night. When I plugged it into another outlet it was fine. Now I shut it down every night and no problems. Now it won't power on even if I go to another outlet. Is there any way to fix it? I tried a hard reset and it did nothing.

@Puminator99 Welcome to HP Forums Community!

Check if the monitor is blank though the computer is turned on, or is the computer not powering on either?

Meanwhile, if the computer is turned on but the monitor doesn't have a display, follow the below steps:

(If the computer is not powering on either, Try with an alternate power cord/adapter and ensure you disconnect all the below cables and check)


Do the following things to prepare for troubleshooting:

  • Turn off the computer.

  • Disconnect all connected devices from the computer except the mouse, and keyboard. This includes removing web cameras, USB devices, thumb drives, camera-type memory cards, and other displays.

  • If the display has a detachable cable, obtain a second display cable for testing purposes.

  • Disconnect the display power cable, wait about 30 seconds, reconnect the cable and then turn on the display. This resets the electronics on the display. Make sure the display has power and the power light comes on when the power button is pressed. If the light on the display remains off, the display is not receiving power from either the wall outlet or the power adapter.

Check the power

Disconnect the video cable from the display and make sure the display power cable is plugged into a power outlet.

With the display plugged in, press the power button on the display. There is a power indicator light located on the display case. What happens to the light?

  • If the power light comes on, the display has power, skip to Listen to the computer and look at the lights.

  • If power light remains off when you press the power button, either the display is not receiving power or the display is defective. Check all of the following items before attempting to service or replace the display:

    • Make sure the power outlet has power and the power outlet matches the power rating for the display.

    • Connect the display to a different power outlet.

    • Try a different power cord.

    If the light comes on, the display has power. Continue to the next section.


(By the end of this article all the issues should be resolved)
