Sometimes when I leave my computer for a few minutes, when I come back the monitor is completely black except for a blue and green dotted line along the top. I dont know what causes this. I have no screensave applied, no standby, no hibernation. All the computer is set to do is turn off the monitor. And then whae I wake it up, the monitor turns on and I see the screen I described above. I am running ME with 128mb sdram with a 32mb NiVidia Geforce4 graphics card. Any hep on the issue is welcome if you have it. Thanks in advance.
