For the longest time my PC's been randomly freezing, which results typically in almost a dozen BSOD a day, sometimes it takes 4 hours, sometimes 4 minutes. The most common error I get is CRITICAL_PROCESS_DIED, although sometimes I also get UNEXPECTED_STORE_EXCEPTION, but that one is rarer.

Here are my PC specs:

Windows version: Windows 10 , 10.0, build: 18363
Motherboard: ASRock, Z370 Pro4
CPU: GenuineIntel Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz Intel8664, level: 6
12 logical processors, active mask: 4095
GPU: Nvidia GeForce GTX 1080
RAM: 68651618304 bytes (63,9GB)


These BSODs have been occurring for quite some time now, I've taken my desktop to two different service stations, but ultimately it still keeps dying. So far I have tried:
- sfc /scannow, which comes up clean
- chkdsk, comes up clean
- dism /online /checkhealth, comes up clean
- Windows memory diagnostic comes up clean
- updated drivers for the motherboard from the website, couldn't install 2.
- updating my graphics drivers and Windows OC.


I also ran WhoCrashed and this is what came up:

Conclusion
5 crash dumps have been found and analyzed. No offending third party drivers have been found. Connsider using WhoCrashed Professional which offers more detailed analysis using symbol resolution. Also configuring your system to produce a full memory dump may help you.


Read the topic general suggestions for troubleshooting system crashes for more information.

Note that it's not always possible to state with certainty whether a reported driver is responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.



I also ran BlueScreenViewer and it pointed out that it's caused by 'Driver ntoskrnl.exe', which doesn't tell me much, since it's apparently not a real driver.

Honestly, I'm not tech-savvy at all, and don't understand most of this, so if anybody could help me out and explain it in basic terms, I'd greatly appreciate it.
