I have a Dual 1 gig QuickSilver machine with 1 gig of RAM OS 10.3. I shut down the Mac a few days ago while I was out of town. When I returned last night, I cannot boot the machine. The power light glows and the Mac makes a slight 'click' and that is it. No fans, no hard drives, nothing. I checked all my cables and opened the box to take a peek. Again, when I press the power button, it glows for a second, and the logic board has two LEDS that flash briefly, and the CPU fan briefly whirs to life and then it turns off. I checked all internal and external cables. All seems fine. It is acting like a power supply problem or internal short or safety is preventing it from progressing in the boot. Is this possible? How do I reset this? Up until last night, this Machine was solid as a rock with no problems at all. No new instals, software updates, or hardware changes have been made in quite some time. I have removed all attached devices except for Apple keyboard and mouse and no luck either. Any thoughts?
