The problem of USB ports not working on a Windows computer could be due to various reasons, ranging from outdated or corrupted drivers to power supply to the USB ports being cut-off to save battery life and other reasons.
Before going ahead with the troubleshooting steps, it is a good idea to make sure that the problem is being caused by the USB port and not by the USB device that you are trying to connect to the computer.
You can check and confirm if the USB port is faulty by plugging another device into the USB Port that is not working on your computer. If you find that the new device is also not working, it confirms that the problem lies with the USB Port.
