It's a nitemare mate,main use for this PC is BF2 and CSS[play a lot of ED clan matches,well did].The last 2 weeks have been terrible, i dont even bother trying to join a server as i know that within 1 minute of joining i will be kicked for high ping [believe me its high]Lowest ping to a UK server i get is approx 14ms.
That was before all this started.Now im lucky if it stays at 100,more often than not its at 700-800 and unplayable.
Tonight made me laugh,i was chatting on msn with a mate and he sent me a 300kb file.Now i know msn isn't the greatest for file sharing speed but it took nearly 3 minutes!
