I have an internet problem. Perhaps someone can help me. [View All]

[Danger Mouse]

I developed the strangest problem with my internet last night. For some reason, I cannot login to Yahoo messenger, AIM, or MSN Messenger. I cannot login to hotmail or Gmail. This happened after I downloaded an update for yahoo messenger. Suddenly, after that, nothing worked, except for the internet itself, obviously, since I am able to post on DU.
What on earth has happened to my internet?
Any ideas?

P.S. as an aside, my computer moniter finally keeled over and died while i was trying to restart my comp. it had been on its way out for awhile (it's not even two years old and it dies on me!), and it's kind of weird that it happened while all of this other stuff was going on, but i doubt it'd related.

incidentally, i used AVG and scanned for viruses...nothing showed up. i also used adaware and spybot. nothing overly suspicious came up.
it all started when i tried to update YM.
