Since we all backup our stuff (don't we?) then you could read Dell's instructions on how to start over with the OS and drivers install and get a fresh start.
OK. My ex boyfriend used to use my laptop (Dell Inspiron B130) before we broke up. I have way too many programs I don't use and WAY too many files that I haven't a clue what they are. He used to download a lot of porn and I want to get rid of all the extraneous crap on here. I only have 26% of free space on my C drive. How can I clean up my computer and make it really Zen? I'm scared to delete stuff that I don't know what it is. Is there an easy way to do a clean up? I don't want anything on here that I don't really need or use.
