Just to add, the WHEA crashdump said it was a PCI-E bus issue:

This is a typical hardware problem. UC means Unexpected Completion caused by the CTO - Completion Timed Out. It means a communication completion got timed out for some reason, most likely because it didn't reach its destination. I've seen this happen from dust and other debris inside PCI/PCI-E ports, cards not sitting properly in their port, PSU problems, a bad PCI/PCI-E card, or a bad motherboard. Unfortunately, it cannot - or at least I can't decipher from it - what device(s) were involved. If you still end up experiencing issues with this, you can try considering fixing any of the aforementioned causes listed. Otherwise, hope everything turns out well for ya.

Just a quick suggestion, you have found a driver fault, ASLDR, which is a driver for your keyboard F functions.
The windows debugger usually can't find the exact (pinpoint) problem, you have to use it to explore the direction it is indicating. It gives you hints as where to look, which is where the analyses comes in.
As Vir Gnarus has found, it's a hardware problem. This type of cause is very difficult for the debugger to locate, as it's better at finding software and driver issues.
There is a possibility that the keyboard is causing the crashes.
Easy to test on a desktop and very difficult on a laptop, an external keyboard won't disable the laptop keyboard.

Whenever I see a laptop with an i7 CPU and discrete graphics card, you have to look into CPU/system overheating, which is the number 1 cause of crashes on these laptops.
Use Real Temp , to check the CPU temps when at idle, under load and/or testing.
Let us know the minimum and maximum temps you get.

Since you didn't give us your System Event Logs, you can look through them for any CPU thermal issues. This is the best way to determine if they are involved in your crashes.

Yes, this doesn't rule out the keyboard for sure and may implicate it, or at least the USB port it's connected too, since USB commonly runs through the PCI-E bus on OEM systems, especially on laptops.

A few days went by, I reinstalled Deamon Tools and my antivirus.
I am stil lable to run the 'problem-triggering' game without any BSoD anymore...

So all that for a BIOS update. That's a bit disappointing though

Thanks a lot for your help, again
