Vista & Games problem -not blu but im desperate-

[X400]

Ok so i recently got a new computer and i loaded Vista Ultimate into it and none of my games work. None of them will connect to any server the only thing i can do with the comp is play single player or surf the web
im desperate in getting this resolved cuz id like to keep vista instead of going back to winxp so thats why im even posting for help on here

hopefully you guys can help me this is what ive done:



so far, ive installed all the latest drivers/hotfixes/patches etc etc available

ive got the vista firewall disabled ive got the user account control turned off

ive nixed my router and got the net running straight into the comp

ive told the games to run in adminstrator mode and winxp compatability mode

and still nothing works... in BF2 i can see the servers but i cant see who's on them and i cant connect to them

in other games i cant even see the server lists...

anything involving connecting to a server it just wont let me do, the only thing im able to do is surf the web

anyone have any solutions????
