Just had a major brain fart/weird glitch, thought it was worth sharing.

My computer wasn't booting at all, kept going to a half BIOS half black screen with a stuck mouse cursor. Previously was getting some random pstate errors after changing nothing for weeks. So I had to click some things in clover to boot up. Anyways, this is the kind of stuff that's going to my mind, as my frikkan BIOS can't even boot up now. I'm like, this machine is fuuuuuuuuuuuuucked up.

tl;dr Make sure you have your PS3 afterglow controller that you use to play roms unplugged before powering on, because your computer might try to boot from it.
