The network here seems to be too slow. Are there any things that I could do to speed things up here on the computer?

How can i speed up my internet/computer speed? I have all unnessary programs delted and i do not have a lynksis router

One of the cooling fans in my laptop (Dell Inspiron 8600) speeds up and gets very loud, it seems only to happen fairly randomly, but often. When this happens my video frame rate is extremely slow. The problem fixes itself when I restart my computer, but then happens again, randomly. Anyone know what I can do to fix this, or why this keeps happening?

My computer is running extremely show when downloading. I have currently been trying to download Aion (a game) since 1:30 pm yesterday and it is still downloading. I know its large but it should not be taking this long. My computer is downloading at 98 KBs/sec. Is there a way to speed up my computer that i myself can do, or a program that iisn’tto expensive. Help?
