They changed the refresh rate.
windows XP SP2, IBM computer and monitor, Pentium(R)4 CPU 266GHz 504MB of Ram.
I was away for two weeks and came back to find my processor on. Computer has a password so it wasn't used.I couldn't get the monitor to switch on. The monitor now, does not switch on every morning when I start the computer.The screen remains blank while I can hear windows booting up. If I just switch off the monitor and switch it on again then it works just fine. If I restart at any time during the day everything works perfectly well. Do you think system restore might help? I suspect someone tried to use the computer and then didn't know how to turn it off so, the processor stayed on for days with the monitor switched off.
Thanks in advance
