its win 8.1 and movie files taken on an iphone
windows crashed last night and got a video tdr failure BSOD, got it running again with system restore
now in device manager it says there's a problem with the display adapter, tried reinstalling all drivers but no joy, can only select 1600 1200 res now, monitor is showing it as 1920 1200 tho!?
there's other 'funny things' it's doing now too
some folders only open for a few secs then crash before I have a chance to open anything
microsoft lifecam has stopped working too
going to try reinstalling windows i think
edit - just tried an old vid card and the resolution issue has gone now - but the movie files still crash explorer/media player
