My neighbor has a gateway desktop that he put into standby mode, and now it wont come out of it. He is running Win XP, probably SP3. When you move the mouse, hit keys, there is no response. The fans are spinning, but the power button is not lit when pressed. The monitor is on. All external and internal connections are good. I tried to boot into safe mode, but since its on standby, its not going through POST. The screen is just black. Im thinking this is either a windows or a video issue as he gets a "no signal" message with the machine running and powering the display on/ off. The machine has discreet graphics, i would install a test video card, but my spares need external power that his PSU does not provide. any help will be much appreiacated.
