I have, in the past (maybe a year ago) arbitrarily looked at this (about this mac) and seen J11 and J12 as being empty. I move those two sticks back to 13 and 14, press the reset button on the board, and the screen comes back and it says I have 6 gigs! Only the 11 and 12 that are in fact not in now, are reported 'not installed'. I can still hear that everything is booting up with the hard drive. ![]() I move the sticks in 13 and 14 to 11 and 12. J13 and J14 are also reported missing (the first 2 gigs?). These are the inner two on the two banks. It tells me J11 and J12 are empty (I have this thing loaded with 8 1gig sticks). I went into the (about this mac) to look at how much memory was reported. But then, the monitor came on! It's working! I jumped into the console and saved the whole log onto a USB thumb-drive. It didn't even flicker when I turned it on. I was watching the 24V on the DV port of the video card. I've been starting and stopping a dozen or so times. I only have the VGA monitor on the stock video card, and that's not even waking up. The supply looks very clean, to my supprise. I bought it to work today and put the supply on a scope to check for ripple (I soldered-in some leads on +12, +5, and +3.3 and they come out the back). Let me know if you've found something with yours. I might try the other button inside again to see what happens, but I have little faith. Actually, it might have been the pulling of the battery that got the chime back, but still no video. After a few more PRam resets, the chime came back. ![]() Just yesterday I thought I'd hook up an ordinary monitor to the DV port on the video card. I let it sit on - dead screen - all night, and in the morning a restart still doesn't help. I would need to hang on the power to shut it down. The computer would be unstable and lock up. I can see something moving around whne I move the mouse. Sometime when I awake it, the screen would light, but be full of artifacts. Sometimes I would just leave it on for weeks, using it, without shutting it down, and it was fine. If I let it stay on - with no video - for a while, maybe 10 minutes, then shutdown and restart, it would work! I later changed the video card, that made little difference. I can see it still boots up and I can open the CD dor with the eject botton, and shut down with CNTL-OPT-COMMAND-Eject. The first thing it did was not have any video. I see theis is an older thread, but I have an old G5 that's been doing the same thing. Although I don't work with Macs often I've been working with IBM servers and Cisco routers for years, so troubleshooting wacky hardware issues is nothing new for me Thanks for reading this lengthy description! If I leave the system on for a good 10 minutes I can physically feel the heat sinks get warm. Would anyone else have some ideas they'd be willing to share with me? Or is my above hypothesis appear to be correct? So I'm pretty sure that leaves only two logical explanations: either the Video card or Logic board/G5 Processors are bad. The PRAM battery is good, I took a multimeter to it and have another known good battery available. No luck with holding down the OpenBoot or PRAM reset key combination during startup I've done the SMU/PRAM or whatever it's called reset close to a dozen times by now, a few of them waiting 10 minutes between each step just to make sure my impatience isn't affecting it When I start the PowerMac up with no RAM, the light flashes intermittently, so I'm fairly certain it's not a memory issue Once that didn't work, I put only the 1g kit Kingston memory in memory bank 1 and still no luck. I removed all the memory and put just the stock 512mb (2x256mb) RAM chips in there. The white light comes on in the front, all the fans spin up fine, and I can even hold the power button in for a few seconds and it beeps at me. Now that I have the new power supply in, the Mac starts up, but there's no chime, and no video output. It made a clicking noise and would not power up, so I went ahead and replaced the power supply with a known good one. Mobile or tablet with iOS 8 or later, or Android 4.A very long story short I have my cousin's old PowerMac Dual 2.0ghz G5 which she has had since 2003.
