Random reboot with no message

[BestMan]

How do I even analyze a random reboot problem if it shows no messages, nor like a crush message, nor after my PC is booted? The reboots are really often when loading OS. And the -v mode does not help because it reboots after the last loading screen which is not affected by -v mode. Sometimes it does not even reboot but just stays there forever in the last loading screen(going very slowly from half progress bar to the end and nothing happens after)
What do I do? Pls help :з

PS everything else except that seems to work pretty good in the hackintosh build

I cannot find System Diagnostic Reports in the Console utility

Where should I look?

Checked every single item at the Console list and searched for time when my computer restarted + checked for time when it froze (freeze at the last loading screen as described above). Did not find any record. Is it even solvable?

looks like the problem is in my wif-fi card TL-WN881ND. When disconnected from the PC, hackintosh works fine. I guess I am going to buy another wi-fi card.
I also messed up my kexts amd7000controller.kext and amd4000controller.kext. Can someone pls just copy it from /System/Library/Extension and upload it here?
