Just updated to w10 from 8.1 (on my spare computer) and it keeps going to the Blue Screen of Death saying. ' Kmode Exception Not Handling RTKVAC.SYS' and reboots.

This happens about every four minuets or so. I have tried lots of fixes that I found on the net but nothing has fixed it yet.

That file is to do with the Sound section and in Device Manager the Audio was not installed correctly with the yellow flag. After going into Safe Mode I disabled it and then did an update of the driver.

RTKVAC64.sys driver is missing from my laptop. Tring to install realtek audio driver to get my microphone back up and working but cant install realtek driver until. RTKVAC64.sys Free Download. RTKVAC64.SYS / lowercase: rtkvac64.sys File Description. Windows (R) WDM driver for Realtek AC97 Audio.

Then went back to normal mode (still left it disabled).bang it went to the BSD yet again so nothing fixed there, even with it disabled. It is driving me mad and if I restore it back to w8.1 will I get the option to update to 10 again? Did a registry fix and cleared all that out. Ran a driver update program I have, no audio came up. Usually if the audio isn't going on other windows os it doesn't do this BSD business. All too much really, they are not making it easy to fix that I can see. As I said at least it is not this main computer so experimenting is not a worry.

Can anyone suggest a fix? Would appreciate that. Just updated to w10 from 8.1 (on my spare computer) and it keeps going to the Blue Screen of Death saying. Windows 7 Build 7100 Activation Crack.

Found a solution! You won't believe it! Since the latest official Vista drivers don't work, I searched for alternative drivers. I found which apparently is a Realtek AC'97 clone.

I booted in Safe Mode and loaded Device Manager. Then I manually browsed to the folder were I extracted the drivers and installed them. When booting back in normal mode, I had sound and no BSOD! And the funniest thing is that this driver is an old version of the Windows XP driver by Realtek! Probably latest official Realtek driver for Windows XP will work as well, but I wouldn't dare to try it once I got it to work!

The Vista driver gives a BSOD and the XP driver works! UPDATE: Today I ran Windows Update which among others it found 'new' drivers for Realtek AC'97 and attempted to install them. I got a BSOD and had to go to Safe Mode and manually replace them. I tried the latest official Windows XP drivers from Realtek, they also gave a BSOD pointing to a different DLL file! I entered Safe Mode once again and manually replaced them with the.
