[QUOTE="dazsnow, post: 720957, member: 66541"] Yup, another "my powermac G5 won't start up" thread. My mac: powermac G5, purchased October 2003. Dual 1.8GHz, 512mb RAM. Never had any problems before. Situation: I plug it in, hit the button, the fans whirl but there is no chime.. after a while a click sound and then the front LED flashes 3 times and then just stays on but the computer won't start up at all. From what I've read from similar stories on the forums, this usually indicates a RAM problem. However I am inclined to think it's a power problem. A few weeks ago I went on holiday and unplugged everything. When I came back and plugged everything back in I went to turn on the computer and this exact same situation occurred. I took the mac (all 20k of it!) to the nearest apple repair shop and in the shop there was no problem - it started up fine. I even got them to test my power cable. So... I took it back home.. and all I did was try and different extension cable and then it worked fine! Now... I've just moved house. When I plugged it in and tried to turn it on I got the chime and a notification on the screen saying that I should restart the machine by holiding own the power button. This happened again the next time I tried to turn it on. The third and subsequent times have been exactly as before... fans... click... 3 flashes of the LED... and nothing. I've tried all the plug sockets in the house and various extension cables but it doesn't look like that's going to work this time. Any ideas? I will try replacing the battery this afternoon but if that doesn't work I have no idea... don't want to have to drag it back to the apple shop again only to find it works in their office fine. Any help is greatly appreciated. Thanks. [/QUOTE]
