DC problem

[lerzba]

I haven't been on for 2 months or so, I'm coming back and I'm having problems with the game and stuff,I get auto disconnected from the game each time It finishes loading,my internet works great,I have the same problem on cable and wireless internet doesn't make a difference, I'm guessing its a computer problem? Game used to work a few months ago on the same computer also I reinstalled the game like 5 times, did windows reinstall, restore 2 times and it still doesn't work, I did 3 virus scanners I don't have any viruses, my computers clean all I have on it is potCO and Xfire, any help please?
