I'm working on a gateway 2000, Intel Pent II MB, 400 CPU Slot 1, 128 meg ram.
Owner had it set to standby, one day comes home and it just will not work, you can turn it off and back on, you can hear the HD booting up, but NO VIDEO, tryed different memory, various video cards, different CPU, and still nothing, So I figured the MB was gone, BUT now I've puting a differnt MB, and still NO VIDEO.

Is this tell ing me that the Power Supply is not functioning correctly?

Or any other segestions would be appreceated.

Thanks
