Desktop distorted, perhaps someone can help?

Hello, I discovered this today and I have no idea how it happened because it's never been like this before.
Enclosed are 2 screenshots. One screenshot is me trying to click and drag from the top left corner of my desktop to the bottom left corner of the desktop. As you can see, I am only able to go as far as the black space seen in the screenshot. The second screenshot is a screenshot of my desktop icons within the extra 700 or so pixels of the width of my desktop. On my desktop, I am unable to see past the 768th pixel(width), only when I do a print screen of my desktop can I see past the 768th pixel. In the screenshot, I am unable to place my cursor in the black space. I am, however, able to place my cursor past the 768th pixel not entering the black space. These screenshots are not altered in any way except for the white text and arrow. Can anyone help me as to why this has happened to my desktop? Or how I can fix it? Thanks

Here are the screenshots

Seems like your video card drivers have gotten corrupted somehow. Try resetting your display to Standard VGA, and then re-installing the drivers.
