    BSOD loop on boot from fresh Win 10 upgrade over fresh Win 7 install

    This is on an old eMachines M6805 laptop that originally came with XP 32-bit. I put a fresh install of Windows 7 32-bit on it which ran fine. I then upgraded that to Windows 10 32-bit. The first time it booted up I was able to log in but got a BSOD shortly thereafter. Ever since it BSODs without even getting to the desktop. The only way I have been able to even get into it is via Safe Mode so I assume it is a driver that it doesn't like but I don't know how to figure out which driver is causing a problem (odd that it all worked fine in Win 7, though).

    Any help is appreciated.

    Hi huhqwerty,

    Welcome to the 10forums.

    The crashes are caused by extremely old audio drivers.
    Updating them could solve it.

    Hi axe0,

    It was the sound driver (AC97 based) which is apparently a very common issue for Windows 10. See this post (if allowed to link to other sites) for details on how to fix it. Basically, you have to uninstall and delete the RealTek driver that is installed, turn off automatic updates since that seems to be what causes the problem, and install the old driver.

    Thanks for the help.
