If your mouse or keyboard is not connecting, it may be due to a variety of reasons. First and foremost, check the connections between your mouse or keyboard and the computer. Make sure that all cables are properly connected and that they are secured in their respective ports. Additionally, ensure that there aren’t any damages to the cords themselves as this could be preventing them from being able to connect properly.
Next, check if there are any drivers installed for either your mouse or keyboard on your computer. If no drivers have been installed then you will need to install them first before attempting further troubleshooting steps. Furthermore, if you have recently updated the driver for either device it is possible that compatibility issues may exist between the new version of driver software and your hardware device – in this case it would be beneficial to reinstall an earlier version of driver software which had previously been working correctly with both devices.
Finally, make sure none of these peripherals are connected via Bluetooth as this can also cause connection problems when trying to use them with a PC or laptop system. If they were previously connected via Bluetooth then try disconnecting them from within Device Manager (found within Windows Control Panel) before attempting reconnection once again through USB cable ports only instead of wireless technology methods such as Bluetooth connectivity options available on modern PCs and laptops today
