[QUOTE="dtravis7, post: 1005526, member: 8287"] Did you try the suggestion that the power button could be going bad and manually short the leads real fast? Besides the Motherboard it could be a power supply issue which would be a lot cheaper to replace. The Logicboard is quite expensive BTW. Do you have any kind of a voltmeter or DVM? If so check all the voltages from the power supply. I am sure there is a chart somewhere on the internet. What model iMac G5 is this? Do you know the basic specs? Replacing the Logicboard while expensive, would do nothing to your data on the Hard Drive unless the tech is a KLUTZ and hurts the hard drive in someway. If you find for SURE it's the logicboard, take out the hard drive and purchase a cheap external case that supports the SATA hard drive in the iMac G5 and hook it to another machine. PLEASE do give us the basic specs so I can check a service manual and get back to you. [/QUOTE]
