No display or black screen on a DESKTOP computer monitor

Monitor is not on

  • It may seem obvious, but make sure the monitor is turned on.
  • If you do not see a power LED (blue, green, or orange light) on the front or bottom of the monitor, press the power button.
  • If no light comes on, check both ends of the power cable to the monitor to make sure it is properly connected.


Computer is asleep

  • If you stepped away from the computer for a bit and returned to a black screen, it is likely that the computer is asleep.
  • Try moving your mouse, clicking the mouse buttons, or pressing any key (e.g., spacebar or ESC) to wake it up.
  • If none of those actions work, press the power button on the tower.


Operating system issues

  • If the computer boots up and displays a login screen for the operating system, but the screen goes black or blank after you log in, there may be an issue with the operating system. A system file may have become corrupted, preventing the operating system from loading and resulting in the black or blank screen.
  • Try restarting the computer, to see if it is a temporary issue and resolves itself with a reboot. If the problem persists, give us a call.
