I'm having some problems with a Quadra 700. The Mac only (now) boots when the power to the HDD is disconnected, and goes straight into the flashing floppy screen.
When the HDD power is connected, the Mac does not boot at all - just a clicking sound comes from the machine. The PSU fan tries to spin too.
I assume this is some sort of problem with the power supply - possibly not being able to supply enough power? Weirdly the whole machine was working fine yesterday, although it hadn't been booted in a long while before that.
Is there something I can do to fix this? Has anyone
