When I press the startup button, the LED#7 Flash one time with red color, and the startup button light only flash one time, the MAC didn't startup. What's wrong with my mac? Please help!
Mac Pro, Mac OS X (10.4.2)
No chimes? Sounds like it has died. It's pretty old, but it may be repairable.
Thanks, Kappy.
I can hear a "dik dik" sound only when press the startup button. And didn't hear sound of the hard disk.
Are you saying you have a PowerMac G5 (2003-2006) predates any Mac Pro (Intel) which won't run 10.4.2
That sounds like a hard drive failure at the very least or a power supply failure so the drive will not work. I'd say you need some repair work. Take it in for service to find out what's wrong and how much it will cost to fix.
