Today, we’ll look at a few options for resolving the Corsair mouse side buttons not working issue in games and other programs like GeForce Now.

What can I do if the side buttons on my Corsair mouse aren’t working?

1. Install the latest device drivers

Corsair mice might be affected by outdated or missing device drivers. Some mouse functions may cease operating due to pending updates if you recently installed a Windows update.

While you may manually upgrade your mouse driver from Device Manager, updating multiple device drivers can be time-consuming.

DriverUpdater, a third-party software updater utility, can automate this procedure and simplify installing driver updates.

Old or incompatible drivers are the source of some of the most prevalent Windows issues and malfunctions. Lag, system issues, and even BSoD‘s can occur if your system is out of the current.

2. Verify that iCUE is active

iCUE is a Corsair-developed utility that allows users to customize their peripheral devices, including the mouse. Make sure iCUE is running in the background if the side button on your Corsair mouse isn’t working.

Open Task Manager by right-clicking on the taskbar. Check to see if the iCUE process is active. If this isn’t the case, restart the tool and leave it running in the background. With iCUE running, see if the side buttons work now.

If the problem persists, use the Control Panel to repair iCUE. It includes a built-in repair tool for locating and resolving faults that prevent the software from working properly.
