how do i fix computer black screen? the computer is on but the screen is black.

 

The troubleshooting steps may depend on if you are using a desktop computer or a laptop computer but we shall do the same for both. Here is a basic troubleshooting steps for monitors to determine if the issue is due to a hardware issue or software issue.

  • Check if the power cable is connected properly to the monitor and the power light is on.
  • If that does not work, try switching to a different video output (eg, DVI, HDMI,etc)
  • if you have installed an external video graphics and the display is blank, switch to the internal video graphics as it could be due to the external video graphic card.
  • You can also check with another working external monitor display (connect the computer with the TV and check if you get the display on the TV).
  • Try removing any external devices that are connected to the computer, this maybe the reason causing the black screen issue.
  • Reset the monitor settings to default (the steps on resetting the monitor may vary from the brand to brand)

If none of the steps helped, go to the UEFI advance option. To enter the UEFI advanced setting option.
