Hello! I have a question regarding my wife's computer. It is an HP a450n, and recently when trying to power it up the monitor, mouse and key board do not show any signs of life except the monitor going into "power save mode" like the computer was turned off. I sought out some "friendly" advice and replaced the mother board, but that did not fix it. I also swapped a know good video card & memory into it. None of the suggestions have worked. If anyone has any ideas they would be much appreciated.
