My parents has a 3yr old Gateway desktop with a 19" WS LCD monitor. Just recently the brightness menu has popped up, maxing out the brightness and won't go away no matter what you do. I turned down the brightness and it automatically maxed out again. I turned it off, unplugged the power cord, even tried setting the brightness through the computer itself. None of the menu buttons work on the monitor other than the brightness buttons. I somehow got it off the brightness menu only to replaced with another menu saying that the resolution may not be set right, or something like that. Either way the menu(s) won't go away and its blocking the lower right of the screen. Is this a sign of the monitor going bad or is the something wrong with the desktop itself?

Those things indicate a short inside the monitor control board inside the LCD.

bad lcd monitor
I would take it apart and clean all the button contacts.
Unless you have taken one of these apart this explanation may not help much.
The contacts themselves are also sometimes to blame. They are tiny tiny little chrome or light duty steel domes (convex or concave depending on how you look at it) that when the top is pressed they pop down and make contact. When released they pop back up and contact is broken.
The contacts are built into a tiny holder with a small white piece of plastic sticking out of the top. You actually have to take these rather small containers that are soldered to the board apart to get to the actual contact. You don't have to unsolder them from the board to service them.
The problem with them is sometimes that tiny chrome or steel dome will split from the middle to the side. Rendering it useless and generally in the down contact position.
If its split I have found the contacts from dead cell phones can be salvaged to replace those tiny domes.
Just to be clear the parts I am talking about here are in the couple of millimeter across range.
