Hi, Go to Device Manager and check what's appearing under Universal Serial Bus Controllers.
Or any unknown device under Other Devices.
If you see any such device, right click on it and click on Update Driver Software. Then click Search Automatically... It should update the driver.

P.S. Since you're using Galaxy S3, install Samsung Kies software from here. This will install all the required drivers.

Hi, try this: [SAMSUNG GALAXY S3 UNIFIED TOOLKIT V7.0] Drivers, Backup, Root, Recovery + MORE [GSM] - xda-developers

P.S. Pls dont be offended when I start my sentence with "Try this".
As you are aware, there is no possible and straight fix to such issues. Hence we are doing "Trial and Error" method.
