Lag attacks in bhd

[Str8h8]

Hey all i have been getting lag attacks lately it dont matter what server i am on.
They usually come every 3 to 5 mins and last about 10 to 20 secs and they annoy the hell outta me.
I have a 2Mbit connection with 512 ram 2.2ghz cpu and a NVIDIA GeForce Ti 4600 with 128 ram.
I never had any problems playing bhd til this crap came outta the blue about a month ago.

And sometimes the game totally freezes and i cant do nothing with the puter ususally during thease attacks i have enough time to (if close enough) to run behind a wall and lay down to wait out the lag attack.

Ive tryed to disable firewall, antivirus software etc but it dont seem to help so does anybody have any other ideas id be glad but right now i am so totally pissed off at this sh|t.
