5. Update your drivers

Each piece of hardware on your system, be it your video card, sound card or others, has its own specific driver, which ensures that different hardware components can work smoothly on your system. However, these hardware drivers are susceptible to corruption. When that happens, your PC performance would suffer and some programs may fail to work properly as expected.

There are mainly two ways you can update your drivers:manually and automatically .

Option 1: Manually update your drivers

You can update your drivers via the Device Manager:

  1. On your keyboard, press theWindows logo + R keys simultaneously to open the Run box.
