Solution 3: Automatically Update the Drivers

Updating the drivers is a very important task, but it is equally annoying as well as a tedious process. You can use programs that can keep all your drivers updated and can download and install suitable drivers for your system time to time or it will notify you if you wish to install them manually.

Driver Update will also help you in avoiding permanent damage to your computer system due to downloading and installing wrong driver versions. Given below is a quick way to do it:

Step 1: First of all, download and install the Driver update on your PC.

Step 2: Once it is installed, it will start scanning your computer system for outdated drivers automatically. Driver Update is going to check the installed driver versions against its cloud database of the latest versions and then recommend suitable updates.

Step 3: You are required to wait for the scanning process to complete. Once the scan is completed, you will get a report of all the problematic drivers found on your computer. Go through the list and see if you wish to update all the drivers individually or all at once. If you wish to update one driver at a time, then click on the ‘Update Driver‘ link present next to the name of the driver. Or you can just click on the ‘Update All‘ button present at the bottom in order to automatically download and install all recommended updates.

Note: It is to be noted that some of the drivers require more than one step to be installed which is why you will have to click on the Update button multiple times till the time all of its components are installed.
