I just installed a new Pent 1.6 gig system and hooked up a Hansol 19″ monitor to it. Every so often the monitor goes blank for 1/2 a second, then comes back to screen display. I cant figure out what is causing this, it seems to be random, but happens at least once every 30 minutes, but not on regular intervals. What can be causing this? I have checked power saving settings, just in case but this no power down settings set for anything less than 5 hours, and monitor is set to always on!!
