Fail to restart

Whenever I try to restart my Mac Pro, the system powers down, the screen turns black down and then it stops while the power light remains on, and then it stops at this point and all I hear is a continuous ticking (from the HD?).
I remember having the same annoying problem with the G3 B/W. I did everything obvious like check the HDs, repair permissions.

MacPro, iMac G5, Macbook, Quicksilver G4, iPod Nano2, Mac OS X (10.4.9), ...Mac Plus 4MB

I suspect the graphic card and the power supply since when I used to be crasy for video games on PC, top graphic cards need a cable from the power supply. In case the power supply wasn't so good the computer didn't start or restart.

I ask the store to check my machine.

Did you get any sort of answer from Apple on this one? I'm getting the same issue.

I do have lots of goodies (2nd SuperDrive, 16 GB of RAM, RAID card, 4 HDs) installed. Maybe the power supply is just having issues.

I'd hate to return this thing. ;(

My 2.66 MacPro has the same issue. I´ve taken it three times to the technical service. 1st attemtp: They changes the HD. 2nd attempt: a new logic board. 3th attempt: After twoo weeks testing they says that doesn´t find any issue. Apple says that they can´t do anything because the machine not fails. My guarantee expires in november and I own a 2500$ defective machine.

This is a random issue and I can´t demonstrate it. I recorded a 25 min. video trying to restart the machine and make a hardware test (it hangs). If I tried to reinstall from the original disks the disk utility couldn´t find any volume or disk. What can I do? I live in Spain and customer service is really bad.

I only hope that Apple read this.

P.D. My fan also makes an odd noise, sometimes this noise becomes into a very noticeable vibration. The technical service didn´t hear anything. This is the video. Sorry for my poor english.

Hi,

My Mac Pro got fixed : My retailer told me when you order a specific machine (aka for me 3Ghz, 8 cores and X1900 XT), they built it from a generic Mac Pro from the stock. In my case, they forgot to change the power supply.

In my retailer spare parts catalog there are 3 models :

- for generic Mac Pro,
- for 8 cores,
- for 8 cores + X1900XT.

Hope it's help.

PS : sorry for my poor english.

Touchdown. This might be what's causing my RAM problem as well.

Awesome. Thanks for staying on this janeiro...

The computer has been checked thoroughly by a Service Provider and it turns out that one of the 4 internal drives is dead. When this drive is removed, everything works great. So one harddrive (not even the startup-disk) can cause a computer to hang completely.

Scary, but ok, I'm glad it all works fine again.

so, do you know what power supply is correct for the X1900? we are having the same issue here, and would like to know if this tip is applicable to us.

Well just throwing my hat in the ring as well my 2.66 Mac Pro is having the same issue. I don't think this started until after the last firmware update. Is that true for anyone else? Shut down goes fine but when i try to restart i get the same "the system powers down, the screen turns black down and then it stops while the power light remains on" problem. This is true in boot camp as well. As long as i choose Shut Down and not Restart it shuts down fine. Driving me nuts...

The restart problem still exists. It definitely hasn't got anything tot do with the harddrives, I've checked them thoroughly with DiskWarrior.
The machine starts up fine and even quits normally, but if I try to do a restart, it hangs during shutdown. And I hear one of the DVD-drives ticking.

So, now what?
Anyone?
Any ideas?

I have the same issue, and I am running a 2GHz Dual Mac Pro. I had my tested at a service shop and they claimed it was my RAM that I had installed that wasn't Apple RAM (yeah right).

Also, this problem did occur/start after the last firmware update.

Did any of you try creating a new user account? Try this but don't copy any settings over from your current account. We did this on a Mac Pro Quad 2.66 that was having the restart issue and it fixed it. this machine has an internal raid as well.
