What to do??
1. Before you do anything else, restart your computer.
2. Check for operating system updates. Needing an update can significantly impair your PC’s performance.
3. If you’re having problems with a peripheral (mouse, keyboard, monitor, printer, etc), try switching it on and off. If that doesn’t work, try disconnecting and reconnecting the device.
4. As a last resort, download the latest drivers and perform a full reinstall.
