According to users, sometimes this problem can occur due to your power supply. Users reported that the issue was a failing power supply, and after replacing it, the problem was resolved.

Remember that replacing the power supply is an advanced procedure, so if your PC is under warranty, be sure to take it to the official repair center and ask them to replace it. If you’re tech-savvy, you can replace the power supply on your own, but remember that changing the power supply will violate your warranty.

Replacing the power supply can also cause damage to your PC if you’re not careful or don’t know how to do it properly. It might be best to contact a professional to avoid any damage to your PC.

3. Reinstall your USB drivers

In some cases, this problem can be caused by problematic drivers on your PC. To fix the issue, you need to reinstall your USB drivers. This is rather simple, and you can do it by following these steps:

1. Press Windows Key + X to open Win + X menu. Select Device Manager from the menu.
   
2. Once Device Manager opens, go to View and check Show hidden devices option.
