I’m running windows 7 with dual monitors.
When I switch on in the morning one of the monitors immediately starts to flash (about once a second) and this will continue through log on and start-up. Eventually I end up with one monitor showing a stable image and the other still flashing.
If I power off (ie not an orderly shut down) and on, go into start up options and choose the last known good configuration, then the screen still flashes all the way through to what must be the last part of the start-up when the flashing stops and both monitors show stable images.
I’ve shut down and restarted during the day with no problems. The problem started about a week ago during which time there have been a few windows updates and restore points set. So I guess the last known good configuration is changing but the problem continues.
Any advice on how to resolve the problem would be appreciated
