Motherboard or CPU faulty?

[LuteFlute]

Intro

So I recently upgraded everything in my computer 3 months ago, everything is new besides the storage devices. Ever since I've upgraded I've gotten BSOD daily and honestly I don't mind, but I've recently gotten into Sims 4 (Never thought Id get into it) and that game keeps crashing within 5 minutes everytime for no reason whatsoever, so I was like f*** it ill finally figure out whats wrong

 

So...
I know that my GPU was working on another computer with no issues and I tested out the ram on another computer, so I narrowed it down to the Mobo or the CPU. To test this I switched out my new mobo and cpu with the older parts from 3 months ago (I put back my old Z270-h and i5-7600k and removed the newer B450-f and Ryzen 5 3600x) and to my surprise its been a day and no issues so far and not a single crash on the Sims 4. I know its either a hardware fault also because ive done a fresh install of windows 4 times and I still get the same issues so it isn't software. I've even done memtestx86 3 times with the G.skill and still doesn't work

 

TL;DR, Is there anyway to distinguish whether the Mobo or CPU is faulty. Thanks!

your problem is you didnt install a new copy of windows... That is what you need to do to fix your problems. Your getting driver conflicts that is causing your crashes and BSOD's. A fresh install of windows will fix your problems.

Sorry when I meant clean install, I also meant I formatted everything, So I have installed windows 3 times, with everything formatted, 3 times.I edited that post to correct the terminology

Yeah, it still crashes. in fact I even tried to run my older ram with all the new specs (to test if the issue was the new ram), and it wouldn't run in XMP, whenever I tried to run in XMP it would reboot 3 times before starting up in non-XMP

is your BIOS up to date on the board?

mmmk, im outta ideas personally. At this point i would suspect motherboard over CPU as the guilty party. 0

Thats also what Im hoping and thinking as Mobos are more likely to fail rather than CPUs

Have close problems and even if you do reset windows you need new windows for that build dont ask why its problem in bios or new windows what every oyu will not fix your problem until you instal new windows

What do you mean by new windows? I installed through a USB 3 times, and reformatted everything through there? Doesn't that constitute as "new windows"? Also the computer is still running fine with the old hardware with no issue.
