FSX tends to lock up when it is "busy" such as maneuvering for ILS. Then it restarts. I run Dual core 3800+, 32 bit, 3g ram, nvidia 7600 video card. At idle on the runway I'm using 504k mem, CPU usage is 50%, and I have 1.6 mb memory available.When just flying along I'm using 530k mem, CPU usage is 60% to 97%, and 1.5mb memory available.Any suggestions on why FSX locks up? Or better yet, how to fix it. Thanks

My first guess is you need a better video card

helloSorry to say but that computer is marginal for FSX.I doubt that you will ever get good performance in FSX but it would run FS9 quite well.I would run FS9 which is really starting to look nice now, Save FSX for when you do a major hardware upgrade
