I have a 2005 Power Mac G5 Duo 2.5 Gigahertz computer which will not boot up. When I turn it on, the power light does not light up, nor does it show a flashing light signal. Soon after the fans start up they become loud. I tried reseting the smu, installed new memory, zaped the PRAM, and gave it some time. Those things helped me before, But not now. PLEASE HELP ME!
Power Mac G5-OTHER, Mac OS X (10.4)
Fixed. All i needed to do was the hair dryer trick. Thanks for all of the people referencing the trick.

Great work, was wondering if that was maybe it, but never heard of the Power light not lighting on account of it... thanks a lot! 🙂
You're welcome.🙂
Bad news, when I turn it off, after a little while, I have to do the trick again to turn it on. Any other tips?
I will update this page when I get a chance to try out the trick (I don't have a heat gun).
Hair Dryer longer closer may work.
I will try out it as soon as I turn off the commuter, or when i confirm what is a "closer" is in hair dryer.
Sorry for the spelling errors. I am using a old Apple USB Keyboard to type until i get a bluetooth adapter for my Macs and PCs so I can use my wireless keyboard.
closer as in nearer. more close.
Did not work.😟
Oh, and by the way, after some time, the G5 does boot up but when I click something after a while, it stops responding.
Get Temperature Monitor to see if it's heat related...

If you have any temps in the 70°C/160°F range, that's likely it.
The memory controler heatsink is at 71.2°C and incresing/decresing.
And by the way, when I jump started the Mac, the highest tempreature in the memory controler heatsink is 72.9°C before it stoped.
Power Mac G5 will not boot up.
