That sentence was a little ambiguous. If the Mac is powering itself down, then you almost certainly have a power supply problem, though it could be a weird ADB problem. Try disconnecting your keyboard and mouse and use the power button on the front of the machine to eliminate some of the latter possibility if the Mac is powering itself down. If it chimes, and then the monitor goes into power saving mode, you may have corrupt NVRAM. Use a super-early PRAM zap to bypass the NVRAMrc. In practice, power up the machine and immediately **BEFORE THE CHIME FINISHES** hit the CMD-OPT-P and R keys at the same time. This can take some practice. This will get you past a bad NVRAM problem. If the machine doesn't chime, you've got a hardware problem. It's either bad RAM, bad or poorly seated CPU or bad motherboard. Or it could be a bad power supply.
