Got a couple of problems... Got this computer that I can't log into my user account anymore. It says not enough memory to log into the specified user account so it takes me to an account with limited options. I've been using a Guest account cause it has more of what I need but all my other files are in that other account which also happens to be the Administrative Account. I also want to reformat the hard drive, but I won't be able to get into that Administrative account until I fix this. Any ideas on what to do? I have a code to erase everything off the computer, If I do that, would I be able to reinstall Windows XP from DOS?
