Fortunately it's not my problem. Have a friend in Australia who's been running FSX just fine on an old P4 3.4 system with an nvidia 5200 256M AGP card. Just in the last few days he's run into a problem.Whenever he runs FSX *or* FS9 everything is ok for about 10 minutes, then screen goes black and a 'no signal' displays. System fans are still running but only a reboot will get him going gain.
This does NOT happen when he is just using the system normally.
He's run the nvidia stress tests for 33 passes and all seems well.
He turned down quite a few FSX settings and all was well for about 15 minutes but when he switched to virtual cockpit - same problem.
I'm leaning toward a bad video card.
Any thoughts?
