Display Issues

I have a B110 desktop. I have recently installed windows 7 on it, 32 bit. Everything works great, except for the display, where I have to slide left right, up down to view pages. I try and change display, it says You cant change this display because the height of your display is less than 600 pixels. I have a 22 inch monitor, so that cant be it. I looked to find new drivers for video card but no option for windows 7. What can I do, do I need to replace card or can I just update driver??

Please help
