Corsair M65 side buttons not working? Corsair is an extremely popular PC peripheral manufacturer that is all about gaming. They create a wide variety of products for customers.

One of the most popular Corsair product ranges is its gaming mice. Corsair has many options when it comes to gaming mice, and one of the most popular ones is the Corsair M65.

The Corsair M65 is an affordable gaming mouse that packs in quite a few handy features. The star of the show, here, are the side buttons. These days, gaming mice are expected to have at least some side buttons.

The M65 is great for games like World of Warcraft and DOTA because of these buttons. These side buttons, however, can quit working from time to time.

If your Corsair mouse side buttons are not working, you may just need to assign them tasks through iCUE. You could also need to reset the mouse or even update its firmware. Unlike standard computer mice, Corsair gaming mice rely on additional software to function properly. If the software is not a problem, you may have a hardware issue.

Your side button issue may be related to corrupted or outdated drivers on the computer. In this article, we will go over all the reasons why your Corsair M65 may be giving you problems with its side buttons. We will also go over what you can do to fix the problem. 

How to Fix This Error?

Solution 1: Make Sure the Side Buttons Are Properly Assigned

The absolute first thing to check when your side buttons are not working in WoW is to check if your side buttons are assigned. They surely aren’t going to work if they aren’t assigned in the software. So, it’s important to set them up first before you can use them. This can be done in the Corsair application that should have been installed on your PC when you set up the mouse for the first time. Once you do that, you can check the settings for WoW itself.

Step 1: Open the Corsair software

Step 2: Assign the buttons on the mouse and make sure that they’re responsive

Step 3: Start World of Warcraft

Step 4: Go to the control settings

Step 5: Assign the functions that you would like to the side buttons

Step 6: Go back to the game and test the Corsair M65 side buttons

Solution 2: Repair Corsair Software 

The Corsair software is crucial in making sure that your M65 mouse is working properly on your computer. Your mouse has to be linked to this application for it to work properly.

If this application has missing files or is corrupted, that can make your Corsair M65 mouse act faulty. This is a very common reason why the side buttons won’t work in Corsair with WoW. The best thing to do in this situation is to repair the application.

To repair the Corsair Software in Windows 10, use the following instructions:

Step 1: Click Start

Step 2: Click Settings

Step 3: Click Apps & Features

Step 4: Select Corsair System Software

Step 5: Click Repair

Hopefully this resolves your problem with your Corsair M65 side buttons not working. If it doesn’t then keep reading this article for a possible solution. Sometimes it’s something as simple as the settings in a program.

Solution 3: Check Program Settings

Even if your side buttons are working fine, you won’t be able to use them if they are not assigned within the program you are wanting to use them in. For example, if you want one of the side buttons to perform an action in Photoshop, you will have to go in Photoshop’s settings and enable that shortcut.

If you are wanting the side buttons to perform an action in a game, such as reloading, then you would have to go in that game and set that mouse button up to carry out that function.

Where and how to do this varies from program to program. I would suggest going to Google and searching for something along the lines of ‘[your program] mouse button settings’.

You are sure to find plenty of guides on how to set up your mouse buttons in the particular program you are trying to use. If you have all of that set up properly and it’s still not working, then you may want to continue reading this guide for more information on how to fix Corsair M65 side buttons not working.

Solution 4: Repair iCUE

If the above methods have not helped, as sort-of a last ditch effort you can try to repair or reinstall iCUE. This software is an underlying system that is required for higher-end Corsair mice to properly function.

Without iCUE installed, you aren’t going to get the advanced functionality of your Corsair mouse such as RGB lighting settings and additional mouse buttons. So, if your iCUE software is having some sort of problem, it can prevent the side buttons from working on your Corsair M56.

iCUE rarely has any issues, but sometimes it does. Before repairing iCUE, you will have to delete the ‘Corsair composite virtual input device’ driver. To do so, perform the following steps:

Step 1: Open Device Manager.

Step 2: Select Human Interface Devices.

Step 3: Right-click Corsair composite virtual input device and select Uninstall device.

Step 4: Tick the Delete the driver software for this device checkbox, and then click Uninstall.

Step 5: Rerun the installation file for iCUE and select Repair.

Step 6: Follow the instructions for repairing iCUE.

Step 7: Reboot your PC.

Are your Corsair M65 Side Buttons Not Working? Most Corsair mice have a reset function can be used to fix unexpected glitches and other behavioral issues like repeating button presses, lighting problems, or general unresponsiveness.

To reset your Corsair M65:

Step 1: Unplug the mouse

Step 2: Hold down the left and right mouse buttons

Step 3: Plug the mouse back into the computer while still holding down the mouse buttons

Step 4: Wait about 5 seconds, then release the buttons. You should see an LED flash if your Corsair M65 resets successfully.

Solution 6: Replace or Repair Your Mouse 

It’s important to make sure that there are not any hardware issues with the Corsair M65 mouse itself. So, check to make sure that the Corsair software properly detects the M65 mouse.

If resetting your mouse doesn’t fix the issue, reach out to Corsair Customer Support for further assistance. If your mouse is under its warranty period, you should be able to get a free replacement.
