Having some weird issues with my Aorus Master X670E

Hi all,

Just recently acquired a Gigabyte Aorus Master X670E motherboard, from Newegg everything went smooth, however I've been having some weird error codes popping up, did some searching around but it seems unique to me only as far as I know

LCD error codes comes up as follows:

76(most frequent one), 8F, or EA

PC runs fine but also I came across an issue I havent had before on my last X670e board I had(ASUS Strix X670E A Gaming), and that would be graphics driver time out, never had this problem on the previous MB

One more thing is I've noticed after installing Windows, I didnt have to activate it, says "activated with digital key", I havent signed into Microsoft at all.

Build:

7950X3D

X670E Gigabyte Aorus Master

XFX 7900XTX

I am still within the return window but I want to get a 2nd opinion on this, I may have to reinstall windows, I already flashed the BIOS to the latest version (F10) i did flash it to (F9) but didnt solve anything.
