ok here's my problem... -i cant sign in to yahoo and windows live messenger.it gave me troubleshooting menu and i click repair and the key ports icon seemed to have that yellow triangle.tried reinstalling but no good. -my IE and mozilla is so damnnnnmmnn slow.it took me an hour to load a page.why??and if it loads too long it'll come out with a page saying cant find server.tried reinstalling it but no good,again. -i cant run any update; windows update,antivirus update,antispyware update,and any kind of thing related to update.it says,could not find server.damn.. -so the conclusion,why my pc cant find server??my aunt's ladtop and my cousins pc had no problems with it,even though we are on the same connection(router).and it has never occured before but why this time and why me?? the internet is connected,the limewire is good,my torrents download normally.and only skype is the only one i can sign in. pliz,and thnxsx....and pliz dont tell me i need to reinstall my windows.i juz did that a couple of days ago.
