Power light goes out but power remains thr...

now this is with a desktop not a laptop right? and the key combo for a reset is Command + Option + Power Button. Thats the equiv.. to a Ctrl + Alt + Del on a windows system. But does you mac turn on and load to the desktop? or does it just start up and hum, and nothing on screen and all peripherals don't respond as well? If that is what you are getting then the power supply needs to be replaced. I've had that same issue once with my PowerMac G4 Dual Proc. (ya i know you can start up and the fan hums and all but thats the fan for the power supply not the fan for the board. if you have a older mac the cost for a new power-supply shouldn't be that much. And you can probably order it and replace it yourself. a good cheap place i've found so far is here: http://stn2.headgap.com/resale/FMPro?-db=OrdersC.fp3&-format=products.htm&-new
