Alright y'all, this ain't a BSOD. And this sure ain't your Mama's bootloop. So I have just put my PC into a new case, and everything works fine....sorta. When I go to power off, it appears to power off, almost fully does, then starts too boot for about 15 seconds, then back to shutting down, and does this pretty much infinitely. Not sure what's going on? It's not totally a problem, as I can just switch off the PSU, but it still sucks and I'd love a hand with it.
