Q: This has happen a couple of times recently and the last time it put a blue box with "out of range 42.9khz/53hz" on it. I have also had my puter reboot itself, but that hasn't happened since I blew out/vacuumed the dirt/dust out of it. (about a month ago). The new problem of power saving has come about in the last two weeks.
A: Check to see if the monitor is plugged in
