Windows 7: Windows started acting crazy

Just the other day my windows started to act weird, i can have my internet up (chrome) and it wont be involved but any other type of window i open up if i try to move it it will snap back to the postion it has been in, if i try to scroll the scroll bar will move and snap back to where it was before, my windows will flash constatntly and if i try to watch a movie my task bar will flash in and out of the full screen movie. this is getting to be rather annoying. any help would be great.
