My computer has been going ridiculously slow for the past couple of weeks . I mean , it was taking FOREVER to get anything done . A five minute video on youtube took ten minutes to load , when it would normally take one or two . So I told my brother , because he is more tech savvy with trouble shooting and the like , and all we had to do was unplug the router , wait a minute , and plug it back in .

OPT: A. My lack of knowledge of anything technical caused me all kinds of frustration .. B. I should have looked online for help but could n't because it was slow .. C. I will never remember what to do in this case because it was all so technical .. D. I knew I should have called my sister because she 'd know what to do ..
Answer the following question: What might have been the real problem in the story ?
