Hi I'm new in this forum, but I'm reading and learning a lot from your experiences. (thank you) I bought a used asus ROG G750JY, which had problems with its nvidia (error 43), freeze, and blank screen. I tried changing the system (win10 --> win8 --> win8.1 --> win10), the drivers, and finally the vbios. I do not know what kind of action the previous owner did on notebook, but at the moment it seems that the video card has 4 gigs and not 8. I tried to update with many versions of nvflash, both from windows and dos, but without success. Then I saved the current bios and changed the values through maxwell bios tweaker. I do not know if the default values were correct for the card, so I ran a cpu and ram downclock. flashing the bios in this way, the board is recognized and started without any problems. Now, how can I proceed to solve the problem entirely? I tried to flash 8 gig BIOS ASUS but I get "gpu mismatch" errors. Thank you very much
