• Switch your PSU. Power Supply Unit converts AC to low-voltage DC that your computer’s internal component needs. Therefore, if it has malfunctioned, none of the external devices with work.

2] Manage Drivers




If your computer is still not recognizing an external monitor, keyboard, or mouse, try managing their respective drivers. The drivers you need to take a look at are:

• Display adapters
• Monitors
• Keyboards
• Mice and other pointing devices.

Rollback Driver


The first thing you can do to fix the error is to Roll Back drivers. To do that, launch Device Manager by Win + X > Device Manager, expand Display Driver, right-click on your Graphics Driver, and select Properties. Go to the Drivers tab and click Roll Back Driver.

If the option is greyed out, your driver is not updated, so, try updating it.

Update Driver


To update your driver, open Device Manager, expand Display Driver, right-click on your Graphics Driver, and select Update Driver.

Follow the on-screen instruction to update your Driver

Reinstall Driver


To reinstall your drivers, open Device Manager, expand Display Driver, right-click on your Graphics Driver, and select Uninstall Device.

Now, unplug and replug the device and check if it fixes the issue.

Now, do the same for Keyboard and Mouse drivers if you are facing any issues with them as well.
