    Monitor will not display anything after computer turns off screen for power saving.

    My screen is set to the default time to turn off to save power. Just built a new computer. I used the same graphics card, monitor, mouse, and keyboard as my old computer. Unfortunately, it seems something is wrong with the new computer that causes it not
    to turn back on. The fans blow, the lights on the keyboard are on, and when I move my mouse, or press a key on my keyboard, I hear and see the screen turn on, and the backlight is lit, but it stays black, flashes "Display Port" at the top left a couple times,
    then goes back to sleep. It receives a signal, but with nothing on the screen... The only way to get my computer screen to display anything again is to restart my computer by holding down the power button.

    This is not an issue with my graphics card or monitor. Tried my old computer again and it has no such issue.

    Anyone know how to fix this?

    (Steps tried)

    Updated BIOS.

    Updated Windows.

    Reinstalled Windows.

    Reinstalled Graphics drivers.

    Tried a different graphics card.

    Tried different monitor.

    Screen turns black, system "hybernating"

    Turned it on - after almost an entire day without touching it - and worked for 3 hours before the same screen black, system hibernating happened again.

    Checked the temperature throughout and the cores registered at max 56 and 50.

    Suggestions?

    My hp laptop wont turn on

    This is a frequent problem am sure as you have already seen from online searches.

    Flea power is usually the culprit here, basically its residual power that remains on the computer even after thecomputer has been shutdown. You can drain the flea power with the steps the other answers have suggested.

    • Disconnecting the battery and adapter
    • Press the hardpress the power button for 30 seconds
    • This should clear the flea power

    If this doesnt work, read this article its about
    a dell inspiron     but the same applies for you hp. It has some detailed step by step instructions

    Monitor wont turn on: I turned off my monitor last night because the light was keeping me up and this morning when I turn the power on the power light will flash but the monitor does not start up. It was working fine and I havent had any issues. Could the monitor burn out simply by turning it off?...
