the motherboard's current version costs £275 fucking pounds, there is no way that's getting matched. I wonder what level of downgrade I can get without missing something noticeable.
Motherboards that cost that much are just laden with 'features' that literally no one will ever make use of. And, I suspect, just create more potential points of failure.
If you can't get it sorted under warranty (via your friend) then just get a decent normal-person motherboard and it'll be fine.
I got this one when I built a new PC in January and it's serving me well. Even when I accidentally ripped one of the PCI slots off the motherboard because I didn't notice they had clips.
Oh, I forgot to update the thread. Yeah, it was the motherboard. Swapping that utterly jiggered Windows but it so happened to be the Windows 10 release day so I had an excuse to do a clean install (of 8 so I could upgrade to 10) anyway.
