It was UNEXPECTED STORE EXCEPTION at the beginning, but then it turned into CRITICAL PROCESS DIED. The BSOD appears after 5-10min of using laptop. I did check updates and then even reset my windows 10 using recovery menu, but it didn't help.
I've kinda figured out what the problem is, and it's either Wi-fi module or chip that provides access to it. So that's why the laptop was still crashing with all internet devices disabled - wi-fi was still supplied with power.
Anyways now I've just turned Wi-fi off in the right lower corner and everything is fine - 0 PCI/PCIe Bus errors
Thanks for the help...
