 How to Fix PC with Black Screen Problems?

A blank screen results from the use of any computer operating system. This could be caused by a failed video card, corrupted computer registration, incompatible video drivers, damaged video cables, loose cables, or a damaged computer monitor.


A failed or damaged video card will not allow you to display anything on your computer screen so there is nothing you can do about it if your video card or computer screen is indeed damaged. However, you can resolve the other two issues, namely a faulty registry and a faulty cable, by following these steps:


1. Corrupted Computer Registry due to Incompatible Software or Hardware

For Desktop Users

Cleaning up CMOS can solve not only a software or hardware mismatch but several issues on your computer. You may have installed a new application, incompatible video driver, or computer peripherals that are incompatible with your computer system. This causes a corrupt computer registry that can be fixed by clearing the CMOS.


A CMOS is a battery-powered chip located on the motherboard. It is responsible for storing certain information about the system, such as the date, time, and other parameters of the system setup when the computer system shuts down.


Turn off the computer and unplug it before doing anything to your motherboard. Remove static electricity from your body by grounding yourself. You can do this by placing your hands on the metal casing. 


Also, make sure that you do not touch the capacitors (those cylindrical objects soldered to the motherboard) or any other sensitive component in the motherboard.


Look for the battery, the same round and silver thing that resides on a usually black plastic casing. Using a small, flat-blade screwdriver, gently remove the battery from its connector. 


Remember the "+" and "-" pages on the battery. Leave the battery out for 10 to 15 minutes for the CMOS to lose its settings. Replace the battery and then restart the computer after reinstalling the covers.


For Laptop Users

Laptop users can configure the CMOS to its default settings by accessing the BIOS setup screen. Depending on the laptop model, you can usually access the BIOS Setup Utility by initializing the computer and pressing the F1, F2, DEL, ESC, or F10 keys while the computer boots. 


These are usually F2 or DEL keys. You can read the guide to your laptop on how to do this on your specific model. Some laptops show you which key to press at boot time.


You will know if you are successful when you see a blue screen, black and white screen, or a similar simple interface running with menus on your computer or PC. Your mouse will not normally work, so you will need to use the keyboard arrow keys.


Find the CMOS installation selection by selecting the menu and resetting the default CMOS values ​​or the option to load the secure defaults. Once you have chosen to load the default settings, you will be asked to choose between Yes and Esc or Esc. Of course, you must press Y to confirm. 


After loading the default values, make sure you save and exit the installation screen. The computer will reboot. You should see the screen in normal mode. If not proceed to the next solution.


2. Loose or Damaged Video Cables

For desktop computer or PC this is a common reason for a black screen on monitor. This happens while transporting the computer from one place to another. Be sure to screw the video cable tightly at both ends, that is, the computer screen and the VGA port.


Also, check if the cable is damaged. The cable may be constantly being pushed down or trampled by the legs of your chair or computer chair rollers, and you may have accidentally shortened it or damaged the copper wires inside the protected cable.


Replace the video cable if you are in doubt about its condition.
