[QUOTE="dtravis7, post: 717307, member: 8287"] It could be the fan, the Hard Drive for two things. I have had some Hard Drives that put out a quite loud whine. Some worked for years, some were dying. Is this Whine REALLY high in pitch? It could be from the Flyback Transformer (Horizontal Output Transformer). The really old Tray Load iMacs had a lot of Flybacks burn out over time due to heat. My 333Mhz Grape iMac blew out the flyback. Mine did not while but would spit every few minutes causing a flash on the screen till on day it shorted all the way out with a lot of noise. I yanked the plug and installed a new Flyback transformer and it's like new again. [/QUOTE]
