So I've had this happen before, 4f error booting. So I switched the profile, and only 1 works. But when I booted in my computer is running like crap. I made sure to OC everything, I haven't fine-tuned it yet, but it takes about 10x longer to load anything. Even Chrome takes forever to load. I just wanted to know if anyone had run into this and they had a solution. It has been a while since I've formatted, and I think I'm going to request a new chip, but if there's anything else to try I'm all ears.
 
Thank You!

Edit: So I'm noticing my GPU is running below 10% even in games. I reinstalled drivers when I first noticed the performance drop, is there anything else to try?
 

There is no reason to request a new BIOS chip. Why don't you reflash the corrupted BIOS position? Boot with the switch in the abysmal position, switch the BIOS switch to the corrupted position once you have booted, reflash the corrupted position, shut down and turn back on from the position which used to be corrupted. Once you have fixed the corrupted position, then you can work on fixing the abysmal position.

Instead of OCing everything, try OCing nothing.
