Windows 7: Brightness toggle not working

Brightness toggle not working

Since yesterday, I cannot utilize my brightness keys on my laptop, nor can I find brightness settings anywhere on my laptop. So my screen is stuck on dim mode. And of course I have a crap aftermarket motherboard so reinstalling display drivers always results in failure. Any help? This wasn't an issue two days ago.
