How to Detect and Install Missing Drivers

Having a few or multiple devices with missing drivers is one of the troubles that are being experienced by many PC users. Such issues are commonly being encountered after PC users undergo some major changes on their PCs, such as OS upgrade/downgrade, hardware device installation, and even when PCs have been infected by malicious software or computer viruses.

This post will briefly discuss how you can detect and install missing drivers on your computer.

A basic way to detect if your PC has missing drivers is to access the Device Manager, and examine if there are devices marked with yellow warning symbols.

To access the Device Manager and check if you have a device or devices marked with yellow warning signs as shown above, you can just click the Start or Windows button, right Computer, click Properties, and then click the Device Manager in the left corner of the Computer Properties window.

After checking your Device Manager, you can visit the official website of your PC provider, and download all the device driver files to get rid of your missing driver issues.

There is also a reliable option to find all missing drivers with ease, and you can visit How to find Missing Drivers page to get more details about this option.


One of the symptoms that may prove that your PC has missing drivers is when a certain feature of your computer is inaccessible, or if you can’t make certain functions of your computer work.

For example, the audio device drivers of your computer are missing if there are no sound outputs, or the USB Host controller drivers of your computer are missing if your PC can’t detect any USB devices, etc.

However, there are other reasons why some of the features of a computer or a hardware device are not working properly and such reasons include having outdated or corrupted device drivers.

For example, there are cases when you need to update the graphics card drivers of your PC to be able to play high-end 3D games. There are also cases where you need to install an updated version of your printer drivers to make it work properly again.

So, aside from detecting all your missing drivers, you must also make sure that your computer is free of outdated and corrupted device drivers.
