did the whea error lead you to the 'fresh install'?
i doubt it's either cpu/mobo if your getting into bios & initializing installation. sounds like a storage issue.
might be worth reviewing all bios settings>storage>boot>csm/uefi settings.
win10 or win11? what's your install media usb?
i'm not sure if you have forgone the block solution from Optimus, but they have blemish blocks (all colors & plates) in stock atm

higher ring can give you some better benching numbers, BUT will introduce instability issues if pushed too high without properly being...
