My Laptop (HP ZBook 15 G5 Mobile Workstation) crashing/Blue screening at random

Hey,

English is not my native language so please bare with me.

I bought this laptop two months ago for work, and my plan was to use my two external monitors at home through the HP Thunderbolt G2 dock with Combi cable. The computer works perfectly fine on it's own but as soon as i connect it to my dock it crashes sporadically (worthy mention is that when i plug my HDMI from the monitor directly into my laptop it also crashes, ruling out a faulty dock). In the log it says "kernel-power id 41 task 63", but i haven't been able to identify a solution.

I've tried multiple suggestions to resolve this issue both from this forum and other sources with no success, hence why i'm here.

Among the things i've tried;
-Set my Graphics options in BIOS to Discrete
-Change HZ and resolution on my screens
-Update relevant drivers (graphics, bios, dock - you name it)
-Set power settings to never to idle
-Set setting where the computer doesen't restart when it crashes.
-Done tests on my memory and hardware

I'm out of ideas and partially hope.

Please help!

A little update.

I did some reading yesterday and i came across a post on a forum where they discussed discrete vs hybrid graphics.

A user mentioned that if you have a Thunderbolt based dockingstation, it will always run on the integrated graphics card. I've tried setting my graphics option to discrete, but if that statement is correct, it makes perfect sense to why it didn't work.

I've now set the graphics to hybrid and hope for the best. Will report back with results.

Previous tries didn't work.

My next thing that i'm set out to try is to turn off V-Sync in the Nvidia control panel. And also change the power scheme to Maximal prestanda.

Will report back with results.

TB3 dock station is getting the video from the nvidia/amd GPU, not through iGPU. Flash the latest firmware also for dock, and make sure you are using Windows version 1809/1903 (1909 is not supported yet, although I have no problems running it)
