What is the problem?

M: I really need to get a new computer.(43)
W: Why? What’s the problem?
M: Well, I’ve had this computer since 2001. It’s so slow to download anything, it drives me crazy.(41)And it often freezes completely, and then I have to restart it. I really need a faster computer, so I can work more efficiently.
W: Why don’t you go to A & T Computers? I’ve used them for years. They use quality components, and they really know how to set up systems properly. I’ve always found their technicians friendly and helpful.(42)
