That a2 and 9c and motherboard screen indicate it's not an issue in Windows, but it occurs already in the BIOS.
Given the broken fan, it's likely to be a hardware issue. Replacing the motherboard is a good solution then. Remember that - unless it's exactly the same model - you might need to reinstall Windows if you install a new motherboard.
My pc is being really strange ever since I came back from my weekend away (I noticed that somehow my CPU fan was just hanging down and not clipped in). Now when I load my computer sometimes it is okay, but often now it keeps going back to a black screen, flashing a dash '-' in the top left and 'a2' '9c' in the bottom right then going back to the msi motherboard screen. I was just playing gta and it has just done it again randomly and now comes onto a recovery screen. Can anyone help please? I only know the very basics of computers...
