problems viewing the whole screen

i am having trouble seeing the left side of my screen; i can only see about 3/4 of the screen. i tried scrolling around, yet i still cannot access the left side. please help, i cant even read the posts.

Is you screen shot maximized?

could it be your computer configuration,..sometimes when you set the pixels, it can zoom in on your computer.....I don't know if you are familiar with computers. Try that and see if it works...
