I am a college student. I really like computers. My major in university was Information Security. A few weeks ago, the motherboard of my desktop computer broke down. I was extremely frustrated. I'm not very skilled at repairing computers. I am extremely grateful for the existence of such a forum, and also very grateful for the sharing of all the kind-hearted people. I sincerely thank the creator of the forum. I hope our academic atmosphere will continue to improve!
