Windows 7 Ultimate Driver signature not working

    Question

  • Ok my Audio Drivers all ways say Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) Ive tried everything to help doing F8 I tap it realy fast sometimes it works but most of the time i dont get the page up. I try doing in Command prompt doesnt work and i try in bcedit and none of these work.

  • Follow these steps:

        1. Open a command prompt with Administrative privileges and type this command:

            bcdedit /set nointegritychecks ON

        2. Restart your computer

        3. Install the unsigned driver.
