Powermac freezes on start up, normal prodcures tryed...

by bugusflair - 5/20/12 11:39 AM

So earlier on this week, my 2x3.2 ghz quad core mac froze... was completely unresponsive, so I force shut it down. It re booted fine then after a few minutes its froze again... I shut it down again, it froze again.

I left it for the night, switched it on in the morning, this time it froze on the start up. I tried booting it in safe mode, the progress bar went up and finished, then it froze. I tried booting it in holding down alt, this showed the HD and the disk that was in the drive, but clicking on either just froze it...

I noticed that it did boot in target disk mode, so I borrowed my sisters macbook and connected them via firewire. When re-booting the macbook holding down alt it gave me the option of booting up on the 1st hard drive on my mac, I tried it and everything worked fine, all my files were still there, it was like i was on my computer...

Then I got my sisters osx 10.6 disk and installed it on my hard drive via her disk drive/computer. This didn't appear to change anything

I then opened up the side and there was a silly amount of dust, so I did my best to rid it of dust... then I swapped the hard drive in bay 1 for the one in bay 3 which still had plenty of space on it. Still all of the same problems...

This is beyond me now, I guess (due to it not reacting to the swap) it cant be a hard drive problem that can be fixed with any erase an install procedures... what could be up with it? Is there anything else I should try at home, or should I get it seen to... any help would be massively appreciated thanks!

That dust is a bad sign.

We see too much and we know the owner has not been keeping up with the required maintenance. We'll clean it up and replace all heat sink compounds as well as inspect for the old BAD CAPS issues (see BAD CAPS on google)

If that doesn't fix it, we give estimates on boards and CPUs (basically the entire guts.)

We never ask if we need to change that. We just do the work. Your beginner or new tech might ask if it's needed but the more seasoned tech will see the condition and then ask for the OK to get the work done.

PowerMac or Mac Pro?

PowerMac or Mac Pro? The distinction is important, because PowerMacs were PPC systems, Mac Pros are x86. It SOUNDS like you have a Mac Pro if you've been able to get 10.6 to boot, but I just want to be sure because the suggestions given might vary significantly based on that answer.
