Huge spikes in Ping

[Shafty]

First, let me say thanks to everyone for all the help over the last few days. The new PC rocks and I now love playing Fallujah. The graphics are incredible now. I never realized that the SAW "smoked" when its fired. Stunning.

Now all the sudden my ping goes from 70 to 300+ in a matter of seconds. The game completley lags out. I've closed down some background taks but to no avail.

Any suggestions from anyone?
