So ive played a specific zombie mod server for a long time and everything was perfect...untill i got a trojan on my computer and had to re-install the windows...after that i could not paly the same server anymore. When more that one person talked on the mic at the same time i started to lagg...and when too many peopole talked at the same time i got kicked out with the message "buffer overflow" My internet connection is pretty good and i cant figure out waht the problem is...and my ping does not go over 100 in the server...im not a very big computer person, but i would sure love play my favorite server again...any help would be appreciated. Thanks, Vadym.

Update your system with the service packs, update all your drivers.
