Battlefield 2142 bug detected ???? -What the h#ll !!

So I installed the new 1.20 update to Battlefield 2142

(Dell XPS 2,16 dual centrio, 2gb, Nvidia 7900GO, sigmatel audio and what not)

System has 'Wondows XP Pro'..

-Also installed 'Northern Strike'

First thing I noticed was a very annoying 'hisssssss' from the speakers, whenever a map loads... -Even if I turn the speakers down.. (this used to be (on older pc's) a graphics problem, -Don't ask me why)..

I play a few of the new maps 'Northern strike' (with the annoying hissssssssss) (ARGH!).

Then a few days later I connect again, and the 'hisssssss' starts as I am booting the map I logged into, -And I play for about 5 seconds, -And I get a message :

PUNKBUSTER

-This 'scenario' has been repeated again and again.. -not even a reason why punkbuster disconnected me..

-Nothing more,- nothing less..

-this is a problem..

-afterwards I have updated 'punkbuster', -but still the same message after a few seconds..

-My connection is 4mbps -Nothing has changed except for the update/northern strike...

I even rolled back my graphics driver, just to see if that worked.. -need I say if it did ?? (no it didn't)

Well, guys, and girls - W.T.F. do I do?

I Really appreciate any input..

Thanks in advance
