Question How can I tell if my CPU is going bonkers or my motherboard?

[Drin]

I'll try to be short and concise. Last night my desktop booted into Windows 10 as normal, then while using the PC everything locked up including numlock and caps lock lights not changing. I hard rebooted using the power switch and then was in a boot loop. I started trying to diagnose the issue and discovered I can boot into windows fine with only one stick of ram installed. Install two sticks and I get a 5 beep error and reboot loop. The beeps sound long not short however.
My motherboard....

Ive tried two types of ram that that was installed:

and my old 8 gig set

I believe that is correct I know the old set is Viper and slower than my new set just can't recall the exact number.

So my main question is is there any way to tell ifit's my mobo or my i3-8100?

CPU's are actually pretty bulletproof as long as you aren't doing any extreme overclocking.
I would say its probably your motherboard having issues.

Having you tried resetting yous bios?
Having you tried updating your bios?

Why do you even have an 8100 in a Z370 mobo anyways

Well you see when my old mobo died I had not been budgeting for a new build as my old one was fine for the gaming I did. So at that point it was be without a pc or buy what I could with the intent to eventually upgrade the cpu when I could. Luckily I'm now where I was planning to upgrade to an i7 before things nose dived

Thanks though going to try a new board and see if that solves the issue
