Q: PM G5 startup light flashing/black screen
Last time I booted this up was about 2 years ago, and it worked. I never used it, as it was inherited from a closed-down art gallery, where I believe it didn't get that much use. I have two of these G5's, one of which works fine, and the serial numbers show they are slightly different.
What happens with the problem computer is that when the power button is pressed it makes the usual startup whirring sound, and I can hear the fan running, but there's no Apple on the screen, which, in fact, is black. Furthermore, the power button at first attempt stayed lit but flashed every 4 seconds or so. After awhile, the fan noise seemed to increase, so it became fairly noisy. I looked up a few suggestions and switched the PRAM battery from the other machine, and put the RAM sticks in order from top to bottom in the first tier. There are 4 128MBs. As I say, it's booted up before, and I never touched it since then.
Firing it up now, I only get the quietest fan sound, and the power light flashes every 4 seconds.
The serial number for this problem machine indicates it's a PowerMac 7,.2, and was manufactured between June and Nov. of 2003, with a production year listing of 2004. (The good machine is 7,3 and made bet. 6/04 -4/05 ) Aside from that, they're identical in terms of processor, memory and graphics.
Advice appreciated,
