I believe I updated the BIOS correctly and I don't understand what the problem could be, could someone please help?
So, your computer was working, then you updated the BIOS, and now it's not? That's not a good sign.
Flashing the BIOS is very, very risky. Doing it wrong can permanently kill the flash chip, and unless you're especially handy with a soldering iron that's not something you can fix and it's not covered under warranty either. It's entirely possible this is what happened.
First thing I'd do is try to clear the CMOS on the board. Your motherboard's manual will explain how to do this. If that doesn't work, chances are you killed your motherboard.
Moral of the story, don't flash your BIOS unless you have a very good reason to, or really know what you're doing. No offense, but given that you thought the LED was for the CPU, it's pretty clear you don't fall into the latter category.
