Can any1 help me pls?

[C J]

Im currently using an Acer laptop as well as an Acer PC.
Everything was working fine till yesterday.

I discovered that i was no longer able to access Yahoo! Games.
I couldn't go in to any of the rooms that i used to frequent.
I can continue to do so wif my laptop but not wif my PC.

I've checked, uninstall and reinstall java but problem still persist wif PC.
I can sign in to yahoo but once i choose the rooms(eg. blackjack), ie hangs.
Similarly, i notice that i wasn't able to click on many links in other forums.

Hey guys, any1 can lighten my load here?
This is just getting on my nerves.
I gotta admit, i've exhausted all my girl power.. haha..
So HELPPPppppp!!!!!!
