Hey guys, First off, this isn't a problem with my settings or screensaver. My Energy saver options are are set to never turn off displays. All my cables are secure. The problem really seems to be with the OS. Randomly, my screens will turn off and on, and my computer will often lock up or crash. Sometimes it happens when I'm in FCP, and just now it happened really badly as I was burning a DVD. Restarting seems to help, but after a while, it will happen again. I'm using two Viewsonic 20.1" widescreens, 10.4.9, GeForce 7300 GT. I've been using this set up for about 7 months and I've never had a problem. I have not recently added or changed any hardware. I haven't recently installed any programs. Does anyone have any suggestions or know what might be the problem here? I'm gonna do some more searching. Thanks.
