Just recently I've been getting messages that my startup disk is full and I have to delete stuff. Okay I understand I was riding on the edge of my disk space so I guess I will have to delete stuff. However after restarting my computer all I get is an empty screen and a default blue wallpaper. Finder and my Dock do not load. I am only able to access that top menu bar because Skype gives an error message when the computer starts up. I was able to start firefox from the apple menu/ recent applications. I am completely lost. Also it seems like cache files for any programs I run have been dumped.
