Need help my computer screen text slightly Blurry

Hey guys I need some help here I just changed to internet explorer 7 and now all the text on my screen is slightly blurry. Its not real blurry just enough to know something isnt right but it makes it hand to read anything or even look at any text because it give your almost the same effect as motion sickness. Thats why I'm asking here I tried searching on google but after a couple minutes it almost made me throw up.

One other thing seeing I'm here I've had this problem for a year or two now but when I scroll up or down the page is kind of wavy or jumpy it dont scroll nice and smooth.

Thanks
