Well I was wondering what in the hell could be causing these problems for my family's desktop computer. They have a cluttered computer with all kinds of useless shit installed, which is making troubleshooting nearly impossible. First of all, you can't restart/shutdown the computer. It just sits there. You have to pull the power. It won't even connect to my router to the internet. Norton won't run, and most programs will run once or won't run at all, and if they do run they don't run right The only hardware change that has been made lately is last week we installed another 256 mb stick of ram to max it out at 512 MB. That wouldn't have an affect of screwing up the whole computer would it? Does it sound like they might have gotten a virus somehow?
