Step 1: Press and hold the Power button until your system turns off.

Step two: unplug all external devices.

Step 3: Restart your system. If it boots up normally, your system is fine. If not, move on to the next repair step.

Solution 5: Reinstall the RAM (Random Access Memory)

If the connection between your RAM and motherboard is loose, it can cause the screen to go to sleep. Since all application data is stored in RAM, any issues with it can cause the entire system to shut down. By reseating the RAM, you can reset it to its default state.

Step 1: Hold down the power button to turn off the computer.

Step Two: Disconnect the power cord from the back of the computer, and then open the case.

Step 3: Remove the RAM sticks from their slots on the motherboard.

Fourth, check its condition. If it's OK, put it back in the same place.

Step 5: Reboot your system and see if the problem is fixed.

Fix 6: Reset your BIOS settings to default

The BIOS is the program responsible for booting up the system upon power-up. Any corruption or damage to the BIOS file can affect the computer's ability to start up and display properly. Therefore, to resolve this issue, it is recommended to reset the BIOS settings to their default values.

Step 1: Press and hold the Power button to turn off the system.

Step two: Unplug the computer's power cord from the wall. Then open its case.

Step 3: Use a screwdriver (or your nails) to pry the CMOS battery off the motherboard.

Step four: Wait about five minutes, and then reinsert the battery into its slot on the motherboard.

Step 5: Plug in the power cord and turn on the system to see if the issue is resolved.

Fix 7: Check and repair damaged files

Sometimes, damaged files can cause the display to stop working. In this case, Windows has a built-in process to look for and fix corrupted files.

Step 1: Go to the search bar and type "CMD"

Step 2: Right-click on “CMD.exe” and select “Run as administrator.”

Step 3: When prompted by User Account Control, click Yes.

Step 4: Type "sfc /scannow" in the Command Prompt window and press Enter.

(This image depicts the command "SFC /scannow" being executed in the Command Prompt. Running this command when your PC turns on with no display output or keyboard power can help detect and repair issues with system files.)

Step five: The System File Checker tool will scan all the files, and fix any corrupted ones that might be preventing your computer from starting up.

Fix 8: Update your display adapter driver

Display drivers are responsible for rendering video, images, and all other visual graphics. If your display driver is outdated or corrupted, it can affect how your system displays things. In this case, you'll need to update or rollback your display driver.

Step 1: Type “Device Manager” into the search box and launch it.

Step 2: In Device Manager, select Display adapters.

Step 3: Right-click on the adapter and see what options it offers.
