I have a Mitsubishi Diamond Pro 920 monitor and a Nvidia Geforce2 MX400 in my 3 and a half year old Mesh computer running under XP (not sp2!) - working quite happily until now. We are a heavy use family and there is just acres of all sorts of software in there giving plenty of room for conflicts.

The monitor began - intermittently then very frequently - switching itself on and off (the front switch light was going on - green - and off - black) until I pressed the on/off switch to off. When I switched it on again it operated OK for variable amounts of time (seconds to ten or so minutes) then went loopy. I have not switched the monitor to another computer and vice versa - yet but checked for viruses - none, changed the Power save settings, ran chkdsk which uncorrupted something maybe related or not, cleaned up the registry using Easycleaner, ran spybot and adaware and removed a few creepy things, removed all my kid's games! and the problem didn't go away - even when I reloaded windows. I was on the point of buying a new monitor then stopped.

I guessed that the problem was that the monitor was going into some sort of power save loop and the problem lay in the monitor or the computer - maybe the graphics card operation.

Anyway - in final desperation I reloaded the latest version of the Nvidia driver and the problem has not occurred in the last five hours - so maybe that was the root cause and the problem is solved.

I'm posting this in case it helps someone out there or you have met this and can give me your thoughts - a google search found one hit on the subject of monitors going on/off crazy but it was a problem to do with some aspect of linux and was written in technojabberwocky. I am not a techie just a user.

Sometimes old monitors reset when they get hot. Things that can cause them to get hot include having the refresh rate set near the limit of the hardware as the hardware gets older.

Verify that your refresh rates and resolution is supported.
