Power Mac freezes at boot screen

My Power Mac G5 freezes at the gray boot screen with the apple logo and the spinning waiting circle. The waiting circle just keeps spinning and the fans become very loud. I also cannot boot into safe mode. I tried resetting PRAM but it didn't help. I am able to boot with the OS X Installation CD. From there I ran the Repair Disk. That didn't fix anything. From the installation CD I can open a terminal and I can see everything on my hard drive. I just can't boot from my hard drive.

I installed Eclipse on the Power Mac the day that I started having this problem. Eclipse worked fine for a couple hours, but it ended up crashing the system. I had to shutdown the computer by holding the power button and it hasn't booted up properly since.

Note: Before this problem had come up the computer was set up so I could choose to login to the machine locally or I could login to a server. Someone else set up the computer that way so I do not know if that might be part of the problem. We used the Power Mac with that type of login for nearly a year without any problems.

Power Mac G5, Mac OS X (10.4.9)

Hi Linear and Welcome to Apple Discussions 🙂

Go here: http://docs.info.apple.com/article.html?artnum=300552

If the information at the above link can't solve the problems, scroll down to number 7 and locate a local Apple store or Apple Authorized Service Provider. I think your PMac needs service.

Thank you, but that link covers what to do when the computer will not turn on. My computer turns on just fine, it just freezes at the gray boot screen. I don't think my computer needs to be serviced because I don't think it's a hardware related problem. I'd imagine that reinstalling OS X would do the trick but I would like to avoid that if I can.

HI Linear,

If you haven't got DiskWarrior, it's worth the money. Go here:
www.alsoft.com It has fixed problems on my PBookG4 without having to take it in for service.

I'm having the same problem. I'm trying to boot with the DiskWarrior CD, get to the gray apple screen and then the monitor freezes and some rogue pixels distort in the gray background. If I try to start in safe mode, I get stuck at the gray screen and the fans ramp up.

Any thoughts?
