High Ping + Laggs..

s everyone knows, ping game depends on the location of the server. Servers Alpha Bravo Dealta Foxtrot CrossFire in the game are located in Canada, and my ping was from 70 do 75 +. That is, I have decided that we must find servak ??"closer" to play well and started to play on servers UK Server 1,2,3,4, and the pin was not raised above 80, I was very pleased.
Suddenly Trouble - I go into the game on the UK server, but I have ping 320. I am puzzled. I suspect that as it is influenced by 2 things: 1) I defragmentoval comp before this Trouble 2) I registered an account as a gift more krosfayr (for the younger brother). Although not the fact that chtolibo could so radically and dramatically affect the ping.
Help razobratsya what happened and how to return the old ping size to 75. Thank you!
