iMac wont start-up. No video no start-up chime
iMac wont startup. No startup chime either. I can hear the CPU fan and some kind of "click" in the hard disk area. Sometimes (rarely) only a white screen. I cant start up form an external or dvd because nothing appears. I tried removing the ram, test one by one and with known good ones.
Any idea?
