One of the more frustrating things that could go wrong is when your PC's screen won't turn on. You may find that your fan is working, but there is nothing on your display, or there is just no signal. This is occasionally referred to as the black screen of death (bsod), fortunately you should be able to fix it. If your computer boots to a black screen here are a few ways that you could remedy the problem. Show
What to do when there is no display when PC is turned on?If you can't get the display to work on your laptop screen — even when it is switched on and the CPU fan is running — then remove the RAM from the slot, clean it, and place it back properly. (You can also try inserting it in another slot.) Note: Before touching any of your PC's internals, remember to ground yourself to remove any static electricity. If you have two RAMs inserted, then remove both and replace only one. If you check the display and it still isn't working, try switching out the RAM. If you are replacing the RAM, make sure that it is compatible with your computer's specs. If the problem persists, then try connecting an external monitor to your laptop. Simply look for the VGA connector (there will be a monitor symbol) on your laptop, and connect it to the external monitor. Then turn your laptop on. If you are able to get the display to work on an external monitor, then there may be a problem with your laptop's backlight bulb or inverter, one or both of which will need to be replaced.
