[QUOTE="Randy B. Singer, post: 1270947, member: 190607"] Generally, if a computer shuts itself entirely off, that means that there is a problem with the power supply or maybe a cold solder joint around the power supply. In addition, if your Mac gets stuck at the gray screen on startup, that also usually signifies a hardware problem, often an external hard drive that is problematic, or failed RAM.
