This just started happening the other night. When a new sound is activated in game system will pause for 30 secs screen freezes then its comes back but I totally lose control of my plane due to no being able to control my plane during that lockup. It's like the pc has trouble finding that sound or playing it right when it needs to. It's happening in other games now.. only thing I can think of is my HDD is down to 500mb free space, due to serious mp3 storage. Any ideas? Im going to do the basics... defrag ect...
