I did what you asked, after Windows loaded I shut down the PC then restarted. The screen still gose blank when the component is plugged in. The computer screen appears on the TV which makes it harder to use. It previously showed on both screens (TV & PC) . Do you think it was some thing we might did? WAIT! My wife just went to Windows mobility center and selected dual screen monitoring and that seems to have done it. I guess it was some thing we did. Thanks for showing us how to get to the boot screen that will be vary helpful.
We're both computer challenged so well be calling on you again, have a happy Holliday
