The other day my pc screen froze, including the mouse and keyboard functions. Had to press the power button in to restart. On restart there is nothing on the screen and the light on the monitor stays amber even though the pc is on. I did get a bios setup welcome screen yesterday if I keep the start button pressed in but was not sure what action to take after that, so through so trial and error I realized that I should enter setup and not hit F1 to continue. By that time after keeping the start button in a few times I think maybe it drained the cmos battery? because now when I try to keep the start button pressed in it just whimpers out.
