@syzygy okay kitten, put your ears because daddy is going to simplify it to you.

I bought a GPU, tried it on my Arch PC. It works for a couple of days but then it stopped working. I tried fixing it but it just won't work, when I installed it I had to use VGA display on my motherboard. So I thought this must be a BIOS problem, then I bought a new motherboard. I installed it in, Arch doesn't work because grub is fucked somehow. I tried it with my GPU too and it won't boot.
