Fix a Black Screen on PC

Before proceeding to more time-consuming solutions to fix a black screen on PC or laptop, your initial step should be to check whether your computer or laptop is not in “Stand By” mode. If so, turn your PC off by holding the Power Button for a couple of seconds. After the computer is completely turned off, turn it on to check if it boots normally.

If this, however, doesn’t work for you, try the following and don’t overlook your monitor:

1 Check Power Supply


An inadequate power supply is one of the most frequent causes of a black PC screen. Even if a system’s fans and lights are working, a PC won’t start properly if the PSU (Power Supply Unit) isn’t generating enough voltage. In such a case, it’s recommended that you grab a new PSU from the market.

2 Reconnect the Cables

Before indulging in time-consuming troubleshooting, ensure the cords are connected properly. At times, loose cables can be the reason for a computer screen going blank. If the issue still continues, try replacing the video cable for multiple connections such as DVI and HDMI. You may also try using a different video cable altogether as the current one might have got damaged.

Furthermore, if your PC has a dedicated graphics card, ensure the monitor is connected to the card, and not to the motherboard. Remember, if you have a separate graphics card for your Windows and you still connect your monitor to the motherboard, it goes blank. So fix this before moving on to the next solution.
