If you can't boot into safe mode, how can you do a system restore But that should work. Make sure the refresh rate is at a good level, i have seen to high of refresh rates give the over range error. I doubt it would be a resolution thing, since Windows is usually smart enough to know what the monitor can and can't handle.Your monitor can't read the resolution you set it at. Try booting into safe mode and switching the resolution in there. If you can't do that, you might either have to hook another monitor up or system restore to like a day before, but you won't lose any data.
