I've recently been having trouble with slow-downs in an a number of my games. Everything will be working smoothly, then the action will soundly stop while the sound continues. Then the sound stops, then starts again, then the action starts again. The whole process takes between 20-30 secs, and seems to happen at random intervals (not during periods of heavy graphic intestity). I've noticed this in both online and offline play, in titles ranging from Half-Life 2 to Rise of Nations. I'm currently running a P4 3.2 and a Geforce 6600 GT, with 1 GB of ram. Any help would be greatly appreciated.
