I've have a problem with an LCD monitor. The on/off button will freeze in the on position (green light on), such that when I push the button, it will not turn off. Most of the time I'm not even aware that it's happened, until I reboot the computer. When the screen goes black, just after the Windows XP logo and just before the "welcome" screen, it remains black with the power light still on. When I unplug it and plug it back in, the screen comes up just fine. This seems to also happen randomly when the screen goes black just before switching to a screen saver. I've tried to disable all running programs with msconfig to see if a program was causing this. I was almost convinced that my Trend Micro Anti-Virus was doing it, as I seemed to be able to replicate and stop the problem by enabling or disabling the program. So I uninstalled the program, but now I noticed that it's happening again. Although I can't pinpoint the problem, it seems to be just predictable enough that I'm reluctant to think that it's an electrical issue. Any ideas?
