I've got a Dell desktop Optiplex Gx270, running xp. Everything was working fine as far as booting up logging in and browsing the internet, but for some reason it won't let me download, or make any changes. It just says i do not have permission. I went into set up and it say Admin Password Disabled. I'm not really that good with the bios and really don't know what i'm looking at, but i was wondering if any of u could give me some suggestion as to how to find out what's wrong with it. I was thinking about refromatting the whole thing, reinstalling the OS, but i'd rather come here 1st. Thanks in advance if u can help me on this issue.
