请以下列词语为关键词写一篇英语短文,computer,problem,complaint

I love using computers.Computers are the essential tools today in people's life.By using a computer,I can easily do the calculation,write programs,and surf the internet.However,problems occur from time to time when I am using the computer.Sometimes,the computer shut down automatically without any notice.In this case,my dad always complaint about the modern technology.Different from him,I never complaint.I love using computers and repairing computers.:)
