RTKVHD64.sys is the Realtek High Definition Audio Function driver.


This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.

This error has been linked to excessive paged pool usage and may occur due to user-mode graphics drivers crossing over and passing bad data to the kernel code.

nvlddmkm.sys is the nVidia video driver.


1. Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you have already experimented with the latest video card driver and many previous versions, please give the beta driver for your card a try.

2. Remove and replace AVG with Microsoft Security Essentials for temporary troubleshooting purposes as it's very likely causing conflicts:

AVG removal -


3. Uninstall GPU-z ASAP.

4. RTCore64.sys is listed and loaded which is RivaTuner/EVGA Precision/MSI Afterburner (known BSOD issues w/Win7). Uninstall ASAP.
