Ok so we have a few options but first can you post the last three groups of number in the product key you bought? Please post that and don't continue with the instruction below until we review it. (***DO NOT POST THE FULL PRODUCT KEY, ONLY THE LAST 3 GROUPS***)
Option 1
This is the recommended action and the one that would be most successful. We recommend a clean install. This will be a fresh start and erase all data from your HDD.
What I would do is create a new disc and download Windows 7 Professional and do a fresh install.
Make sure you backup any personal files that you have on your PC. The actions we will follow will erase all data and start fresh
(Only need to perform Part 1 on the tutorial below unless you want to go further -- WARNING -- PERFORMING THIS ACTION WILL ERASE YOUR HDD, BACKUP BEFORE FOLLOWING THIS TUTORIAL)

Grab the correct ISO for your product key from My digital life. You need Windows 7 Professional 64bit (Needed for Option 2 as well ***)

Create an install disc with the ISO you downloaded in the previous step (Needed for Option 2 as well ***)

Perform the clean install, the link below will help

After installing, update your Motherboard. I suggest downloading all updates (Important -- If you download any Gigabyte software or if any Gigabyte software is installed while installing drivers, remove the program. Gigabyte software is notoriously bad and causes BSODS sometimes)
GIGABYTE - Motherboard - Socket 775 - GA-P35-DS4 (rev. 2.1)
Also update your video card
GeForce GTX 285 | GeForce
Option 2
This is risky, since we have a counterfeit copy of Windows, the results are unpredictable.
Follow this post by Gregrocker exactly (This option required that you create an install disc. See above where the *** is in red.)
Downgrade from 7 Ultimate to 7 Professional
Option 3
Windows 7 Downgrader tool. I've never used this, so this is at your discretion
