computer screen goes black but computer still running

You can go online if you boot in safe mode with networking.

You will need to go online and download the most up to date driver for your device and install that.

Upon this reboot if the problem persists then the driver is completely corrupted. Windows will detect the display adapter that is installed and reinstall the driver for the device.

Go into the Device Manager under display adapters and right click your display adapter and click Uninstall.

If you find that the screen works normally (it doesn't turn black) in safe mode, then there is probably a corrupted drive for your video card (safe mode loads the generic windows driver and not the one specific to your card). 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. Simply look for the VGA connector (there will be a monitor symbol) on your laptop, and connect it to the external monitor. If the problem persists, then try connecting an external monitor to your laptop. If you are replacing the RAM, make sure that it is compatible with your computer's specs.

If you check the display and it still isn't working, try switching out the RAM. If you have two RAMs inserted, then remove both and replace only one. Note: Before touching any of your PC's internals, remember to ground yourself to remove any static electricity. (You can also try inserting it in another slot.) 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.

Screen Black, But Can Boot In Safe Mode.
