I have a Gateway 2000 Desktop that was having some problems. It would shut off spontaneously and had become very slow. I decided to reformat it. I used the cds provided to me by Gateway in order to do so. I had two: a drivers cd and an operating system cd. The first time I did it, it seemed as though it was working because it completed a good amount but at some point I spontaneously got a blue screen error. I assumed it was a one time thing and so attempted again multiple times. It didn't seem to work. I also tried to use another Win XP cd to try and install an operating system but that was unsuccessful as well. The only other OS cd I had was an old Win 98 one. I used this and was able to actually get a working system on to the computer. But naturally, I did that in hopes of eventually being able to get the computer back to the way it was the day I got it. I do not know what to do at this point. I don't understand what the problem could be, whether it has to do with the software or hardware is beyond me. Maybe someone has some advice. I would really appreciate it. Thanks.
