Hi ChrisWood50,
I'm Stefano an Independent Advisor, here to help you.
First of all, try to unplug the USB receiver and plug in on another USB port.
If that doesn't solve your issue, then uninstall and reinstall your mouse driver:
- Press WINDOWS + X
- Click "Device Manager"
- Click "View"
- Click "Show Hidden Device"
- Click "Mouse"
- Right click on your mouse
- Click "Uninstall device"
- Click "Detects Hardware change" (monitor icon)
If you have a bluetooth wireless mouse, try this way:
- Press WINDOWS + X
- Click "Device Manager"
- Click "View"
- Click "Show Hidden Device"
- Click "Bluetooth"
- Right click on your bluetooth receiver
- Click "Uninstall device"
- Click "Detects Hardware change" (monitor icon)
Then retry to associate the mouse.
