-=PCTechTalk=- Re: Monitor blinks off and on when booting

Hello Rick-

Mine does the same thing. I am on Windows ME and using two dual monitor 
video cards to enable me to utilize three monitors.

The tech explained it this way: Upon boot up, the computer (not just Win 
ME) temporarily stops sending signals out to ALL attachments/peripherals 
you have. It then sends one signal at a time to each peripheral or 
attachment. If that signal makes its way back to the computer- it 
temporarily stops again, and send another signal out. It is verifying you 
have the keyboard attached, the mouse is present, the monitor is present 
(It is interesting in my case to watch the monitors come "alive" then 
seemingly die one at a time!), printer is present and turned on, repeating 
rapidly until it determines what is present and powered on. My external 
modem has its own "power up display." All the lights burst on, the computer 
verifies it is present, then the modem turns around and verifies the 
computer is present. After finding a computer on and connected, it will 
then connect to the Internet.

The photograph printer has its own set of lights and they, too, have a 
power up display. I have learned to watch mine- if there is a problem- 
usually by watching the lights, I can find the problem much faster.
