Hey everyone. I just upgraded from Windows 7 to Windows 10 and since then the numlock light on the keyboard is constantly going on and off randomly - every 20-30 seconds or so. Once it goes off, if I turn it back on it turns off again instantly the first time and then stays on the second time for another half minute or so. Never had an issue with the keyboard on Windows 7, so I'm a little confused by what's going on. Tried a different USB port, but no luck there. Any ideas would be appreciated. Thanks.
