CPU: AMD R3 2200G Non overclocked whatsoever
Mobo: Gigabyte Aorus B450I
RAM: Team group 2x8 GB
Has been working fine as a browser/office pc for ~6 months, suddenly booted to this one day. The first boot had the artefacting shown above but froze. 2nd boot onwards it's just a black screen, nothing's coming on at all.
I suspect the GPU in the APU is broken, but is there any way to confirm that it is the APU that needs RMA instead of the mobo if I have no other replacements on hand to just test each one?
