Gigabyte UD3p Constant Freezing

Ok so I built a new computer, and have been having a problem with constant freezing, and not responding from a lot of programs, especially windows explorer. It started with an error message when I was booting up that said DES is turned off, please use application to turn on again. I uninstalled the dynamic energy saver application but that doesnt seem to be the problem. I tried updating the bios from f6 to f7 but that didn't help. It also will not shut down properly, when it gets to the screen that says windows is shutting down it just hangs there. My specs are:

Gigabyte EP45-UD3P

I could not find the option for USB Legacy Support. Here is my bios settings, if this helps anyone.

I will try that. I reinstalled windows again and so far everything is alright but it was the first time for the first few hours so who knows. I do remember reading something about the large size seagate hardrives failing. Was there a fix for this, should I update the firmware for the hard drive or not?
