Hello MacRumor users, (As a first time poster this might be in the wrong section, please let me know if so.) I own a Macintosh Performa 6300CD, mostly original, OEM 1.2 GB HDD, Apple CD 600i, Mac OS 8.1, 64MB RAM, Farallon Ethernet LC PDS card and a (something or other) 56K modem card. I am doing some routine servicing and attempting to connect the Mac to an iBook G3 DV 466 MHz (Clamshell) with the Chooser via AppleShare, and every time the Mac would lock up, the hard disk park and only the mouse would respond. This would lead to having to unplug the Mac, replug and then reboot. I opened the HDD to see if there was anything wrong with it, and as I was working with it, the Mac suddenly shut down. It booted up normally but then the HDD wouldn't spin up. After opening it again to take a look, it shut down again and now every time I turn it on, it will not chime, the green led will shine, the HDD will not spin, and a black screen. When you power on or off there is 3 clicks from the speaker. I don't think the PSU is dead because the fan is still spinning up and power to the system, but did the MoBo die or is it something else. Recap? Any help would be greatly appreciated for both the networking issue or the power issue. Thank You.
