Recently when I boot my machine it gets to the desktop then changes to a lower resolution, and of course the Icons have moved. It doesn't always happen, I have updated the graphics driver but it hasn't made any difference. Any ideas system restore has not worked.
I have just been back into Display properties and I have changed the monitor from Default to generic. I have rebooted 3 times and it has been OK. I will just have to wait and see what happens. If it occurs again I will have to do as you say and check the card. Thanks RP
