I got a second powermac G5 for peanuts. it will boot, but everytime I turn it on an off I have to press the buttons on the monitor im using it on before video will appear [100% not the monitor, it works fine]. When it does get video, there is no chime and no keyboard or mouse will work whatsoever, there is a flashing question mark/mac faces on a folder that should indicate it needs an OS, but being that no keyboard will work I cant eject the cd. I've tried official mac keyboards and normal USB ones and no dice on either. Also after a short while of idling on the flashing question mark screen the fans get REALLY goddamn loud. if I turn it off then immediately back on the fans are back to being quiet so it clearly isnt an issue with temps video attached: video of the general issue https://www.youtube.com/watch?v=rqESSfO7piA loud ass fan: https://www.youtube.com/watch?v=KK-xN23JEq8 [videos may be still be processing, please wait]
They are water pipes on the G5. It is still worth looking into, it's not as if the waterpipes models didnt have fans too. http://www.xlr8yourmac.com/systems/G5_CoolantLeak_Repair/G5_CoolantLeak_Repair.html
Dying PS3s have pretty much same behavior. I think all water coolers need maintenance. http://www.xlr8yourmac.com/systems/G5_coolant_leaks.html
I see, I removed the cpu [its a single cpu machine] that has a large tower heat sink with it and cant really see any leaked coolant, bearing in mind I dont have a torx driver to get the heat sink off the cpu but most of the pics were evident without it being removed.
just a thought, but could the OS be corrupt or the hard drive on it's way out? also maybe check the caps on the motherboard. other than that, I don't know, pour petrol on it and set it on fire, give it a Viking funeral
No, I think the motherboard is just fucked since I can't get it to respond to keyboard prompts that open the disk tray, and we all know how expensive mac replacement parts are. I think honestly I'll save the case for a project and either offer the parts on her for free or give them to a family member who farts around with apple crap a lot.
COMMAND+OPTION+P+R sequence , that might be too new of a system for that command tho.. resets the pram I believe
You can gut the G5 and go to lazerhive and get it modified for a ATX mobo for some hackintosh goodness
Can you get a picture of the heatsink. This screams motherboard / cpu failure, which is typically attributed to water cooling issues. But i have seen the air cooled models overheat and kill the cpu as well.
