In response #1 there were six questions and you gave the answer as "Yes". I've tried to work out what "Yes" means in each case and mostly that makes no sense at all. For example:
What happened? Answer Yes .... what does that mean?
Blank screen white or black? Answer Yes. Well, sure it was one or the other but which, "Black" or "White"?
Have you tried a different monitor? Answer Yes. Well what happened when you did this?
There is no way anyone can attempt a diagnosis, especially remotely, if all we get is meaningless one liners. As posted it could be about "anything", so all I can suggest from that is you try "everything".
