McAfee was implicated in DPC Latency spikes leading to video and audio stuttering on G75/G55 Windows 7 systems. Perhaps the conflicting driver failed to uninstall and is still causing problems on your laptop.
1) You could try using a utility like Driver Sweeper to confirm McAfee is completely UNinstalled. McAfee may even have their own utility to cleanly uninstall the product.
2) You could run the BlueScreenView utility by Nirsoft to examine the MiniDumps and obtain the filename(s) of the driver that may be the likely cause of the BSOD. It may be from a different 3rd party product.
3) What Antivirus software did you replace McAfee with? AVG Antivirus has also been implicated with this BSOD on Windows 8 systems.
4) Folks on
www.eightforums.com (see the thread I referenced in my first post) will actually debug your MiniDumps to help isolate a cause.
5) I see from your previous posts you've installed the NVIDIA drivers several times. It's fairly common for NVIDIA driver remnants that failed to uninstall property to cause problems. If you are not performing a 'clean' NVIDIA install by choosing "Custom Install" and checking the "Clean Install" checkbox, start doing it from now on. You may need to use Driver Sweeper to remove the problematic NVIDIA driver remnants.
