5 Best Ways to Fix No Display Issues on Windows PC

Fix #1 – Check Your Monitor Connection

The first thing that you should do is check and ensure that all the connections are intact. If you are using an HDMI cable to connect your CPU to the monitor, make sure that the ports are clean and there is no issue in the connection. 

Sometimes when the table moves, these connections loosen up. Not to mention the dust factor can also cause the connection to weaken. Check for the monitor status through the LED indicator mentioned on it. If you use a dual monitor setup, ensure you connect the primary one.

If you are using a docking station like the Dell WD19 & it is not working, or there is any other device used, try removing and directly connecting a single monitor to the CPU, as it might be the issue. 

Fix #2 – Clean Your Power Supply

The Power Supply in your CPU can be considered the liver for your PC (as the processor has already taken heart). Without it properly functioning, the PC won’t run. Over time dust and power voltage, issues tone down the performance of the power supply. 

If the computer turns on, but no display on the monitor issue has occurred after an abrupt shutdown of your PC due to a power outage, chances are that the power supply is short. 

In that case, your power supply unit needs to be replaced. On the other hand, if that was not the case. Simply clean the power supply fan, as dirt often causes it to rotate slower, resulting in one such error. 

Fix #3 – Try Connecting the CPU with Another Monitor or Source

If you have an older monitor or a TV supporting HDMI connections, try connecting your CPU to it. Check if the display turns up. If it does, your PC is fine, and the issue lies with the monitor. 

You can also connect the monitor to a different CPU so that it is clear whether the monitor is working or not. It is possible that there is an interface issue between the CPU and your monitor. You can patch that up with a simple driver replacement, and your PC will be intact again. 

However, if the display is not on even after changing the monitor, then things might be serious. In that case, jump to the next fix.

Fix #4 – Re-Install the RAM and Reboot

Try unplugging and plugging in the RAM when nothing else works to turn on your PC. Understandably, you might need to be equipped to do so. However, that is what you need to do. It is more typical than it seems regarding CPUs and PCs.

All you have to do is – 

1. Loosen the cabinet of your CPU and open it.
2. In the cabinet, you can spot the RAM on your motherboard. 
3. Simply loosen the RAM by detaching it from the motherboard.
4. Quickly clean the dirt off the RAM and re-attach it to the PC.
5. Put together the cabinet, and you are done.

Simply press start on your CPU, and it will turn on. What it does is it refreshes the entire memory of the RAM and motherboard. It tricks the PC into working fine unless the same issue is triggered again. This means it will surely bring back the display on your monitor, but as soon as you restart it, the issue might occur again.

• Once it is finished, simply close the command prompt window,

Wait to restart, as there is one more thing you need to do. 

2. Update Your Display Drivers & Optimize PC Performance
