When I turn on my desktop Mac the unit will have power, it will do the traditional Apple sound, but then nothing...the screen just stays black. After about 3 minutes of this the computer's fan begins.
This problem is sporadic...my cpu will start fine for a week, and then three days of blackness. Any guesses?
