This tool is approved by Microsoft and Norton Antivirus. After several tests, our team concluded that this is the best-automatized solution. Below you can find a quick guide how to do it.

  1. Press Windows Key + X and choose Device Manager from the menu.
  2. When Device Manager opens, locate your audio drivers in Sound, video and game controllers section.
  3. If you see duplicate entries, right-click one of those duplicates and choose Disable from the menu.

    1. The image stops;
    2. the sound stops, but in my headphone i hear a high tone sound (like nails scratching on a chalkboard);
    3. the computer doesn’t respond and I need to Force restart.
    4. After i restard and check for errors I don’t see anithing worng, no error in the event reporter, just that i restarted my PC.

    Cand you help me find the source of the problem?

    Have a nice day!

  • Just to share my experience. If the PSU back switch has oxidation, when the wattage consumption rises, it will not be able to drive all the necessary juice to the system and for that reason, the system simply reboots… Just replaced my PSU switch and the problem just went away!
    Best regards,
