I am running SuperMicro PDSGE with Realtek AC97 audio. After install of Windows 10 (Version 10.0.10240) yesterday, my computer blue screens withRTKVAC64.SYS as the problem. Uninstalled audio device through safe mode, no Realtek drivers available from Realtek's website work. Audio worked just fine in Win7 prior to installation of Windows 10 Release yesterday 7/30/2015 (Version 10.0.10240). Device Manager does not find any compatible driver available and does not allow manual installation of driver.
