Dumb computer

So im sitting at the library right now to post this blog. I'm not here because I dont live close by or have a computer. I live one block from campus in an apartment where I pay quite a bit per month for cable and internet alone and my computer has the nerver to not work. I think I have a huge virus in my internet or something because everything else works on my computer. However, if my internet opens it only stays open anywhere from seconds to no more that a few minutes until it closes no matter what im doing. This makes it extremely hard to do work and very frustrating. I have no clue how to fix it and what is even wrong since I know next to nothing about computers. However, Im hoping to get it fixed at home this weekend YIPPIE
