So today i decided to install steam on vista (previously had it on xp, have had vista installed since launch) and the installation goes smooth and i decided to download Counter Strike: Source (dont flame me) and it is installed and everything and i start playing it, i get into a couple of servers fine but after 10mins of steam running my internet suddenly goes off. I was disconnected from Xfire and steam isnt letting me join any servers but somehow i can still talk and hear on both ventrilo and ts. I decided to end steam and my internet is back up again, meaning internet explorer and other apps are working fine again. Now can someone plz tell me what the problem is, it is being allowed by my router, my ports are forwarded and opened. Thx for any help i get.
