Hi ,
You may go to Device Manager, right click your hardware device in the list and select Update Driver Software; then click Search automatically for updated driver software.
Note: Drivers on the Windows Update site are directly provided by hardware manufacturers. Microsoft tests drivers in various environments before they are published; however, we cannot guarantee all drivers will work on all hardware platforms as there are
too many different models, although their hardware ID are the same as the standard version. In some cases, due to hardware modifications by different manufacturers, the driver updates may cause some error.
At this point, I suggest install or update the latest driver for Windows 7 to check the result.
Please try to remove the third-party antivirus software and Clean Boot to check if the issue persists.
