iMac not displaying files in finder

Hi,

New to the forums here. I have an early 2008 iMac Core 2 Duo. I have never had any problems with it until recently.

When I try to view the contents of a folder by opening it in the Finder, rarely will it actually show me the files. More often than not, it will look empty, or will have a very "jumbled" look... see attached photos.

Any suggestions?
