We do want to help you! The problem is, we can’t do much with the Windows Event Viewer logs that were received, especially considering they weren’t in English. 
Vermintide 2 operates in protected memory and would never be able to directly crash your PC, but due to it’s demanding nature it can highlight an instability in a component - subsequently leading to your PC crashing - which I believe is the case here.
Especially considering you experience this not only in Vermintide 2 but in Jump Force too, a hardware problem is likely (but unfortunate) reality. In all honesty, your best bet would be to take your PC to a repair shop. From an online support perspective, it’s very hard to determine what could be the cause without having the PC physically in our hands. I hope you can understand.
