Why won't my G5 boot?

Answer by  fishy (1085)

When a computer boots, the first thing it looks for is memory (RAM), next it will look for the processor and a video output to display the results as it posts. Next it will look for a hard drive with an operating system to start. You can troubleshoot each of these components in order to find the culprit.

First, ensure that the monitor is on. If this is not the problem, try plugging the G5 into the power adapter to ensure that the battery did not run out. The second option would be to remove the battery and plug the power adapter in to ensure that the battery is not dead or disrupting the boot.
