It seems that whenever I try to download something, the internet freezes up and doesn't reposnd. A message pops up saying it stopped working. This happens whenever I try to download something. sc1 maps, sc2 maps, growler guncam (had but removed, getting again). No matter what it is, my internet still crashes. How do I fix this?

"The internet" does not crash. Screenshots please.

So the browser crashed? Try using another browser like IE if your using something else already and try downloading with that.

What you mean with "Internet" is probably your browser, the program that allows you to access (browse) the Internet.
What browser are you using? Reinstalling that browser might fix the issue.
Or just use another browser. Chrome and Firefox are recommended.

By recommended he means get them...
like right now.

ping the router

type windows key + r then enter
type "cmd" without quotes and press enter
type ping 192.168.1.1

If you don't get a response, type ipconfig
ping the "default gateway" instead.

If you get a response, try to download something, and see what happens to the router.

Upgrade to AOL 9.0 today.

But really, it could be a virus causing it. Open Task Manager and see if theres any programs that dont look like official windows stuff, or things youve installed. (Generally the description is what you're looking at, if its blank, chances are its a poorly coded virus with no thought into it.)
