This bluescreen occurs whenever I open Adobe After Effects 2017.2:
Not sure if it is the same problem.

this time you have graphic issue:


VIDEO_DXGKRNL_FATAL_ERROR (113)
The dxgkrnl has detected that a violation has occurred. This resulted
in a condition that dxgkrnl can no longer progress.  By crashing, dxgkrnl
is attempting to get enough information into the minidump such that somebody
can pinpoint the crash cause. Any other values after parameter 1 must be
individually examined according to the subtype.
Arguments:
Arg1: 0000000000000019, The subtype of the bugcheck:
Arg2: 0000000000000002
Arg3: 00000000000010de
Arg4: 0000000000001c8d

Hello everyone,

First of all I'd like to thank MagicAndre1981 and other members for their great work on this thread!
I am having a similar problem as everyone else, I attempted to troubleshoot it myself, but alas can't complete the final step of identifying the root problem.

My specific error is:  ntoskrnl.exe!KeSynchronizeExecution+0x2160
And continues to drain CPU, I have attempted to update everything from audio drivers to intel chipsets. 

I can't seem to be able to link this to any specific driver in WPK
I have recently updated BIOS to 2.4.2 after this analysis, but alas no change.

Appreciate the help.

Thanks, Ryan.

The cpu usage of system process is very low and here only ntoskrnl.exe!MiZeroPageThread uses some CPU usage. I see you use Chrome, here disabling HW acceleration fixes the ntoskrnl.exe!MiZeroPageThread usage.

That is what I find very strange, however when investigating on Process Hacker (and even task manager), the "System/Idle" Processess are consuming >60% of the CPU, and once broken down further are;

1: 15%-  ntoskrnl.exe!KeSynchronizeExecution+0x2160 
2: 20%  ntoskrnl.exe!KeSynchronizeExecution+0x2160 
3: 25% ntoskrnl.exe!KeSynchronizeExecution+0x2160 
4: 15% ntoskrnl.exe!KeSynchronizeExecution+0x2160 


Being an example, however, I cannot extract the exact clash or issue these processes are having with a particular piece of software.

Chrome currently consumes ~%20  or so.

Many thanks, Ryan.

System-Idle  is fine, this means the CPU does nothing. this value should be as high as possible.

 Having trouble figuring out why system.exe is using so much cpu.  Any help would be appreciated.  I'll PM the file link.

The furthest I can get is to see that it is ntoskrnl.exe and resulting from DbgSetDebugFilterState.  I've tried to identify anything on the system that might be set to debug, but I cannot find anything.

Thank you.
