I have a Viewsonic E70f Monitor and the "Brightness" level box keeps popping up. I can hit the menu button and it goes off, or if we're not at the computer, it goes off itself. Any idea what's going on?

I did some research on that monitor, and I appears that there are significant hardware problems that come up frequently. Of course, make sure that your drivers are up to date. I found what appear to be updated ones here:

In any case, reviews do point to frequent hardware problems with your current model, most notably capacitor problems according to a few review website, such as:

I hope it is a driver problem, best of luck!
