    Yes, I have it installed, that was some of the crapware that came with the computer when I got it, never bothered to remove it.

    So yes, my computer is OEM, to answer your original question.

    I performed a system restore to August 16th, and that completely fixed the problem. I will start to reinstall updates (which were the majority of removed items) and see if one of them is causing the problem. I'll post the results here so someone else with the same problem may find a solution.

    Also, thank you to everyone who posted offering their advice, I appreciate the help.

    Well, apparently they were important updates I removed. Restarted my computer and saw the "Do not turn off your computer" jazz. Let it do it's thing, and was still able to adjust brightness after the updates, so update away anyone who's hesitant, it should not cause any problems :P.
