how to do hardware troubleshooting ?

Hi, after finalizing my first build :
MOBO: ROG CROSSHAIR VIII HERO WIFI
CPU : AMD RYZEN 9 3950X
GPU : AMD SAPPHIRE RADEON VII
RAM: 32Gb G.SKILL TRIDENTZ 3200MHZ (F4-3200C14D-32GTZSK)
FANS:3 BEQUIET! SILENTWINGS 3 120MM HIGH-SPEED PWM
3 NOCTUA NF-A14 140MM PWM CHROMAX BLACK
FAN HUB: THERMALTAKE COMMANDER FP 10 PORT HUB FOR PWM FANS
HEATSINK: Zalman CNPS20X
HEATSINK GPU: RAJINTEK MORPHEUS II CORE
and had it run windows 10 for a few weeks, i'm facing major problems... W10 doesn't want to boot anymore. It loads for a few seconds, says it encountered a problems and gets in a never ending rebooting loop...
I have to admit i tried out the ClockTuner for Ryzen (CTR by 1USMUS) setup and probably didn't finished everything properly. So did that screw up the bios ? I reset the bios, tried to reinstall W10 on another internal SSD etc, but to no avail.
Is there any way to do hardware troubleshooting to see what is the culprit ?

well, i cleared the CMOS, removed its battery, and that made windows boot, but only to get itself again into a never ending rebooting loop.
So i stripped down everything, swapped the RAM, and - for the moment - that's what made things work again (i did have to completely erase my NVME disks though). Adding the original RAM sticks to the mix, got everything stuck again. Removing them made the system work... So obviously it was the RAM.
I'm a bit upset though. I mean, i got the best RAM i could get on the market : 32Gb G.SKILL TRIDENTZ 3200MHZ (F4-3200C14D-32GTZSK). I did a mild overclock, being careful with the voltage, so was that what caused the problems ? Anyway, is there a way to "reset" RAM to factory defaults so to say, or must i consider these sticks ready for the trash can ?
