Hi everybody! My computer is failing to launch the finder. All other applications work, and i can even access files through them. Also, when i should be in the finder, the top menu bar does not show. I'm thinking i just need to do a clean install of OS 10.3. Anyone know of any other ways to do it? I've never done a clean install and am afraid of losing files. When i do a clean install would it wipe the HD? Thanks in advance!
