I have a IIe I got on eBay a few months but have not really had time to do much with it. When I turn it on sometimes I get a rythmic and loud "clicking" noise and the power LED on the mother board with pulse in time to the clicking and I get no power. It is sometimes accompanied by a high pitched whine noise. I can sometimes remove a few cards and get the machine to power up.
Bad power supply?
