I have used my laptop which I bought 7 years ago efficiently especially for school documentation, online job and other related Internet activities. I even built my own several websites because of this laptop and I was able to update them periodically. It had never been gone to the computer shop. Its performance was indeed reliable. However, I have notice lately that while I was doing my computer work it suddenly closed. I was of course in trouble for my work hasn't be saved. What is the possible problem of my laptop and how could I solve it?
