I replaced my PSU, my GPU and the case, in the process of switching everything over something happened that is making a keyboard interface error pop up during POST, as well as making POST take about 10 minutes when before it was almost instantaneous, making getting into the bios almost impossible. I can't install the drivers for the GPU as the bios has seemingly locked out the disc reading drivers and now the disc reader will stop POST in it's tracks if I have it connected during. I've tried everything I can think of and nothing is working, dear god help me.
