I was working on an important document that needed to be completed by this afternoon. I did not think that would be a problem at all. I stopped for lunch and to take a quick break from work. When I got back on my computer nothing was responding not even my mouse. I had thought all these issues were resolved with the new operating system, but I guess I was wrong. With windows 7 freezing I was worried that I would not get my assignment in on time. I needed to get the computer working right so I ran down and bought more ram.
