Frequently, as I'm in flight, I get a loud sound, kind of an electrial short sound. Hard to describe. Like a very fast jackhammer or something. The sim freezes, computer locks and I must pull the power to reboot. Not sure but many times it appears that I was switching views or going to or from external view. Today, just from 2d while enroute. I have a Creative LiveDrive 5.1
Anyone with the same problem?
