Hi there, I keep getting start-up disk full messages and prompts to close programs, otherwise the computer freezes or crashes. I have 50 GB of free space after deleting a whole load of stuff. I've followed numerous troubleshoots, but most involve freeing up space. I'm confused by this, because I can sometimes have a few programs running, but sometimes I get messages when I just have word on the go. I need to be able to run word, excel, photoshop and the internet concurrently. I never used to have a problem. Computer freezed again with just internet and word running whilst writing this message! Thanks very much for your help!
