Hey all. I have been having this problem for 3 year and counting. I figure I'd give it a shot and ask here.
Problem: When doing any number of things on windows my pc will become unresponsive. I can still move the mouse, but nothing can be interacted with. The System interrupt process will very often spike to 100%. The biggest cuplrit seems to be when using any web browser (I have tried chrome, firefox, edge, opera and safari with no change). That said it has happened during pretty much any operation on the PC you can think of (Games, watching videos, opening a document, etc). Latencymon seems to show that my DCP and Latency are quite high even when idle. dxgkrnl.sys seems to be the biggest offender, quite a few other seems to cause issues as well (The entire log for about 20 minutes of various tasks is included below).
What I have tried so far:
-Fresh install of windows (2 times)
-Updated all drivers (many times over the last few years)
-Unplugged all USB devices
-Updated the Bios
-Disabled all power management settings
-Disabled any power management from the bios
-Installed an SSD
-Removed Avast Antivirus
-Removed Citrix Client
-Disabled Windows High Precision Event Timer
-Disabled all Audio Devices
-Replaced Memory (And increased it)
-Replaced CPU
-Replaced GPU
-Replaced SSD
Here is my latest Speccy:

I have also attached my LatencyMon and MiniToolBox Files and will gladly attach any logs you would like.
