[Dom 91]

ASUS ROG Maximus X Hero (Wi-Fi AC) LGA 1151 (300 Series) Intel Z370 SATA 6Gb/s ATX Intel Motherboard

Sorry Im a total noobie with computers, I was gaming with my buddies and all the sudden my pc just crashed and the code "7f" kept popping up on my motherboard, I tried to clear bios from the button on the motherboard and that way I Got into the bios settings

Before it wasn't even booting

I dont know what to do next
I tried reverting to default but then nothing showed up on screen but the pc would boot up with a different code

EDIT Now its showing 55
Which seems to be memory not installed
