I would greatly appreciate some help with a problem I'm having. My son has been logging onto remote servers and I think someone attached some sort of keylogger onto his computer and they stole his on line gaming account. Since that time, we can't start up his computer. It goes to the welcome screen and then when we try to log on it briefly shows the desktop screen and then goes back to the welcome screen where it says "saving settings". I've tried calling Dell tech support and have spent two hours with them and accomplished nothing. I own a mac so I am sort of useless with the PC format. I would reinstall the system software on the mac-but apparently a dell doesn't come with system software? What should I do?
