Go to Users/you/Library/Preferences and move com.apple.Finder.plist to the desktop. Log out and log in, or restart (or relaunch Finder by holding the mouse down on the dock's Finder icon while pressing Option and selecting Relaunch).

If this solves the problem, reset your Finder preferences and trash the plist. If not, put it back and log out/in as above.
