Would a failing power supply start up the computer after all power was drained including removing of the CMOS battery. But, just shutting off the computer waiting and then turning on the computer cause the computer not to start up and give the impression that the video chip on the motherboard was not working?
Thanks,

If the computer wouldn't turn on, most likely the video card isn't bad. When a power supply is going awry, sometimes it may turn on the computer, sometimes not. Make sure all cards/ram are firmly in place, possibly remove and reseat them. If you still have the same result, trying replacing the power supply with a backup one if you have one.
You also might want to check out the cpu temp, if it gets too hot it will shut the comp down and if it is too hot, the comp won't turn on.
