My son's 17" imac PPC G5 was not booting up. After a trying a couple of things I got it to boot using Disk Warrior and reparing the file directory. At that time I also ran DW's hardware test which said the drive was fine. My son hard restarted it shortly after I fixed it and it wouldn't start up again. Just a gray screen, no apple logo. When I tried to use DW again it told me there were problems with the hard drive and it couldn't fix the problem. I tried to fix the hard drive in target disk mode using Disk Utiltiy and Drive Genius. No luck. So I pulled a working drive out of my Mac Pro and reformatted it and swapped the internal drive of the iMac with it. There were no DIP switches to set. Started up the imac with a Leopard retail disk thinking I would just install a fresh system onto the replaced internal drive of the iMac. Disk Utility on the leopard disk didn't see the hard drive. Now I'm beginning to think it's a logic board problem but I can't find the original disks to do a Hardware test with. Is there some other way to test a logic board? Or some other idea that I'm not thinking of that could be wrong with the machine?

if you recall a thread I started trying to get help on why the Mac Pro was crashing... I finally narrowed it down.After speaking to about 4 different people at apple.... they had me run the Apple Hardware Test off the boot CD.I took out EVERYTHING except the 2nd DVD burner (Apple Branded Superdrive from my old 2.5 Dual G5)... and ran the test.The Hardware Test ACTUALLY FROZE IN THE MIDDLE OF THE RAM TEST.I thought I had bad aftermarket ram... as it wasn't playing nice with the Apple ram when I added them together.Looks like I had fine aftermarket ram... the Apple ram was bad.I REPLACED the Apple Ram with the Aftermarket Ram... and the Hardware Test completed fine.So, now I'm going to be calling them again in the morning and letting them know what happened. I wonder if they'll just let me RMA the bad ram, or if I'm going to have to lug this dang thing down to an apple store.I WONT BE HAPPY IF I HAVE TO DO THAT.Oh, and no more lockups since switching out the ram... and all the other quirks (not able to burn CDs in Windows, sloooow Internet page draws, etc...) are all but gone now.
I have a new mac mini running OS 10.7.2 and I have just noticed problems with keyboard and mouse intermittently not working, along with other random glitches that seem to be hardware related. I tried restarting while holding down the "D" key to run hardware test, but all I get is the computer trying to get onto the Internet to restore. It then asks to choose a network, and when I drop down the menu of network choices, my home network is not listed -- only my neighbor's.  Right after purchase I cloned my OEM system drive over to a faster HDD, and the OEM drive is now an external backup. I wouldn't think that would matter since everything has been working fine for the last 3 months. How can I run a hardware test?

Lately the machine is not detecting wireless keyboard, trackpad, and mouse unless the iMac is restarted. I tried to run the AHT using the restart and holding the D key but this doesn't seem to work I'm not sure how to run the AHT using the original DVDs, especially if the original OS was Leopard or Snow Leopard.Â

How can I run AHT on my iMAC 21.5 inch, MID 2011 and Mac OS X Lion 10.7.3 (11D50)? There were no DVDs in the package, no restart key-stroke combination connected to internet-aht, no aht is included in the package I bought and downloaded from Apstore. One of the 4 rear USB ports seems to be death from the very first moment. I would like to use the AHT to see if this is some SW misconfiguration or is it a HW problem.
I have a 17" unibody MBP (early 2009, specs below). It was running hotter than usual the other day, so I F2 booted into AHT to run a diagnostic. The status box within AHT showed 1 second into the 1st pass, and never got beyond that. Several seconds after that status message was displayed, the cursor froze. The time counter never advanced after that, and although I waited a long time, nothing happened. The test froze.Â
I've tried it several times more. It once worked, but every other time has frozen. Checking the "extended test" box, or trying to run in loop mode has made no difference - still freezes at "1 second".Â
I've had this machine for 3 years, OS's Leopard through Lion, and this has never happened before. I last ran a test, successfully, in January. I've not changed any components or suffered any damage since then. Memtest (ver 4.22) says my RAM is fine. (I ran this because the first portion of the AHT is the RAM component.) Aside from the aforementioned overheating episode, which disappeared, my machine's been fine.Â

My friend has a MacPro with 10.7 on it. He upgraded his OS by buying it on the App store. Now he has a weird screen at start up We would like to run Apple Hardware Test on the install DVD but as mentioned he bought it from the App store.The only file we get is an installer (4.2 GB) but it is not a start up disk.
i dont have the hardware test anymore. I've upgraded to Lion. I have read that you can reinstall it from the original install disc that came with the mac but i lost mine. is there any other way i can gat it? On on a macbook pro 17 inch mid 2010?
What means hardware test fault 4Mot/4/40000003:HDD-1255? I´m searching for the reason of frequent freezing and finder freezing, freezing in Safari too, and got this result with extended Apple hardware test from CD. Checking volume by Lion recovery tells: volume seems to be o.k.

Recent switcher here. Picked up a G4 17" iMac, and LOVE it.
It could use a RAM upgrade, though. For some reason, the internal RAM isn't being used. The System Profiler claims the spot is empty. The easy to get to one on the bottom seems to be working fine, but it's a lowly little 256.
I'd like to upgrade to its full potential, but am concerned the problem with the internal might be a logic board problem. Any way to tell?
Should I just get a 2gb stick for the known-good slot? Where can I get one for less than the $87.99 Crucial wants for a 512mb?
What's the best way I can test RAM in an old iBook G3? It had a bad module so I replaced it. All seems okay now, but I want to test it to be sure it's all good. Normally I'd just pop in Memtest86+, but Memtest86 doesn't support PPC (obviously).
I don't have any disks for it or anything, so no Apple Hardware Test disk.
I ordered a i7 15" Macbook Pro high resolution anti glare screen over a week ago. I've been reading lots of forums on the subject and have heard about the small print, yellow tint to the bottom half of the screen, the laptop not sleeping etc.
So I contacted the store to find out about the possibility of returning it if I'm not happy. They said I can spend all the time in the store with it but as soon as I leave the store there is a 15% restocking fee. It hasn't arrived yet but I'm expecting it any day now.
Can someone tell me all the tests I can perform in the store before I leave?
I have a MAC OS X 10.4.11 IBook G4 1.1. It's acting up on me. Crashes often and freezes as well. The only CD I can find is the Mac OS X Tiger Install DVD. Is this the Hardware test cd as well? If yes, how do I get the hardware test started. I tried the "restart while holding "C" and "restart while holding the "option key"". Doesn't work. Don't see a hardware test option. If no, Can I download the application?
What is the best was to diagnose possible motherboard faults on a Mac? I'm having various problems which appear to be hardware related (i.e. re-formatting, re-loading OSX, etc don't seem to fix them and the problems appear at different times running different processes) so want to check the motherboard out.Typical problems are a USB hard drive suddening going off-line, the DVD burner suddenly resetting itself for no reason, screen not redrawing properly etc. and all these only happen occasionally. The only test I can find is a RAM test (various programs allow this including Tech Tool Pro 6) but is there a way to test other components?
I read somewhere that memtest can be used to test the memory of your mac. I tried it and it didn't even know what memtest was. Is there a way to test the memory in the unix shell?
I'm stuck between knowing if my MBP has a bag logic board, worn out plugs going Into it, or other reasons. It will not power on at all. About 5-10 minutes prior it was perfect. The battery had power, and when its not plugged up the green light is very bright. I figure since the I/O board is connected to the Logic and it shows power, that it may indicate its ok. But i dont know, since its not directly hooked to it. Apple / Geniuses and Other shops just give me quotes on changing out the logic board after observation of it not getting power...never have said anything relating to "After Testing the logic board...." So I am wondering, whats the secret? how is it done? CAN it be done at home? or, does anyone know what the shops/techs use to test boards?
I have a busted DVD drive, and I need to run the AHT utility. I heard it was in the /system/Library/CoreServices/ folder. It's not for me. And so, pressing "d" or "f2" on a reboot doesn't work. Anything I can do to run AHT without getting my DVD drive repaired first?
I've managed to find a practice test for the 9l0-509 server test, but I can't find a practice test for the support essentials test anywhere (and I don't mean the 10 questions from apple). I'm taking the exam soon, and a practice test would greatly help.
I'm running an extended Apple Hardware Test on my 4Gb MacBook Pro. It's been running 50 minutes and isn't even 25% completed going by the progress bar. It's been on the same step (memory pass number 2) for pretty much this entire time. Is this a sign that something is wrong with my MacBook Pro? It was purchased new in June of this year.
