1. Open the Device Manager and expand it one by one. There may be something wrong with the hardware driver marked with "exclamation point", such as the network card driver (network card driver) and the biometric device driver (that is, the fingerprint sensor driver, because the driver of my laptop is not suitable for installation).

Note: drivers without exclamation marks are probably the problem! My reason is that the driver of the "biometric device" (fingerprint sensor) mentioned above is not installed correctly, and there is no exclamation point, which means the display is normal. At this time, you can directly disable the equipment that you "suspect" has a problem, then right-click "disable" after expansion, and then see if your computer is still ringing from time to time. If not, it means there is something wrong with its driver.

2. Go to your computer brand, official website, and download the hardware driver corresponding to your model and computer system.

3. Uninstall the original faulty hardware driver first: expand it in the device manager and right-click to uninstall it.

4. Open the driver downloaded in official website before and install it. At this point, the problem has been satisfactorily solved!

Tip: This problem usually occurs after the system is newly installed or updated. Mine is a new windows8. 1 There is a problem after the system is updated. Windows8. 1 will automatically install the hardware driver for you. If it is found that it automatically installs the driver after uninstalling the faulty hardware driver, click Close, otherwise it will still ring from time to time. I've done win7 before. I didn't know what was going on at that time. It's really troublesome. Now it's finally solved.

Also, you probably use the driver wizard and the driver installed, which is really easy to go wrong. You'd better go to official website to download the corresponding drivers and install them one by one.
