Part of the screen missing when playing games

[Tc3001]

For some reason, whenever I'm playing a game that runs at a resolution of 640x480, part of the screen gets cut off. This gets annoying in some games when that part of the screen can be somewhat vital. To show you what I'm talking about, look at this pic:

Can anyone help me?

i have 2 recommendations, one is to set your desktop resolution to 640x480 just before you load the game and second would be to increase the game resolution if its even an option.
