When I was young, my family got our first computer. As years went by, I wanted to get a new one, and my father agreed. We went to many stores and looked at many flyers  . At last we bought an HP computer. During the first week, I noticed that our computer had some problems. I tried to fix it, but failed. Finally I had to phone the HP company. After five hours' hard work, the computer still did not work. My dad didn't have a choice but to return the whole thing. A few days later, we decided that I should go on the internet and order some parts to build a new computer by myself. It was not an easy thing for me to deal with it, but in the end I finished. From these setbacks  , I have learned, and now believe if the computer that I bought from the store didn't have problems, then I would not learn how to build a new one. Even though I spent lots of time on it, I know it wasn't a waste of time. I now have a self-built computer, and I am very pleased. Which of the following is true according to this passage?
The HP computer was very cheap. The writer built a new computer by himself at last. The HP company managed to mend the computer at last. Dad didn't like the newly-built computer at all.
