Mac Pro :: Early 2008 : No Video, No Sound, DIAG LED's Report GPU Not Initialized?
Jul 5, 2012
Early 2008 Mac Pro picked it up second hand. dual 2.8 GHz E5472 8GB (4x2GB DDR2 6400F) originally had ATI Radeon HD 2600 XT now has Nvidia Geforce 7300GT. this is what i get. I plug in unit the power light comes on the fans run, Memory card diags LEDS run and turn off. the logic board LEDS are all off when the button is NOT depressed and when the diag button is pressed i get the standby, the EFI done, and the power good LEDs But thats all i get. What i dont get.No Video, No Sound, DIAG LED's report GPU not initialized, Power LED normal system goes into standby with a press of power button. ODD opens when eject button is pressed.
What i tried:reset PRAM. and SMC? Checked power connections on logic board. Swapped out Video card for Nvidia Q2000 Quadro 1700 and ATI HD2400.Put Geforce 7300GT into HP Workstation and it works fine. Chassis Clean. Reseated Memory cards and DIMM's?

I purchased this card for my Mac Pro:
"NVIDIA GeForce 8800 GT (early 2008) Graphics Upgrade Kit for Mac Pro"
I spoke with multiple Geniuses. I spoke with AppleCare. Everyone is telling me that this is the card for my Mac Pro model. They looked up the model number and confirmed it. The original ATI card works in the machine.
I received the card, installed it, booted the machine, and had no video. Just two blank 20" displays. I tried using one display, reset power management, did a few other things while on the phone with a Genius. Nothing.
AppleCare sent me a new card (same model). Same issues. I'm looking at two blank displays right now. I'm as frustrated as I could possibly be. Are all the people I spoke to at Apple completely wrong and could this be the wrong card? Multiple people looked up the model number and they all point me to this card. It doesn't work, and since my ATI card works, I doubt it's the machine.

I use a mini display port to HDMI to get the video and i use audio Y cable splitter for the audio.i can get video but not sound. If i disconnect the HDMI cable from the T.V. then i can get sound. If the HDMI cable and the audio cables are connected at the same time i can get video but no sound. I called Sony and according to them there is no setting on the T.V. that would help. My theory is that it's some kind of setting in the imac that prevents it from sending audio and video to the tv at the same time. Unfortunately i have not been able to figure it out.

I am interested in connecting my early 2008 Mac Pro to my HD TV so that I can easily watch iTunes movies stored on the Mac Pro on the TV.
I know the Mac Pro has DVI video out and the TV has HDMI video in, and that there are adapters between the two. Will this be as easy as connecting my spare DVI port to an open HDMI port?

Well I never thought about this happening anytime soon, but it did. The weird part is that the Windows partition still boots up and works fine. Should I go ahead and replace/upgrade the HD now or just reinstall OSX? I'm kind of thinking about upgrading...

I recently got this Mac Pro (Model number A1186, EMC 2113) with two Quad Core 2.66 GHz Intel Xeon 5150 processors, 16GB of RAM (both RAM riser slots completely filled with 4x2GB sticks of 667MHz DDR2 ECC FB-DIMM each), 2x1TB clean HDDs, and an ATI Radeon HD4870 (512MB DDR5 memory) video card with 2 DVI ports and an S-video port. (I bought the HD4870 later after I found that the one that came with it, an ATI X1900 XT, was part of a recall [sadly this recall ended in 2011.] Plus, the fans on the X1900 were revving up REALLY loud.)The reason I'm posting here is because the darn thing will not "boot." The machine starts up fine (HDDs spin up, lights on the RAM risers illuminate momentarily, etc.), but there is no output out of either of the DVI ports. Not even a gray Apple screen. I have tried the DVI cord and the monitor on two different machines and they both work perfectly fine, and now I have no other Mac available to test the video card on. I'll just have to assume for now that it works. The video card, after the machine is turned on, has three of the four diagnostic LEDs lighted.
The ones that light up are D1601, D1602, and D1603; the other one, D603, does not light up. After some searching around on Google for a little while and sifting through forum after forum, they all seemed to agree upon the fact that these lights were from the two internal power cables (D1602 and D1603) not being plugged in and that there was a critical temperature error (D1601). Note that a) both power cables are in both power slots and hooked in securely and b) these lights turn on immediately after pressing the power button. A light tug from both ends on both cables assures that these cables are not going anywhere soon, and I doubt that there would be such a heating issue as soon as I press the power button, especially since all the fans are running fine. My first thought was that maybe the logic board wasn't getting enough power, but I have no idea on how to check this as almost everything besides the RAM risers and the extension slots are covered by something.Another problem I found is that some of the diagnostic LEDs that should be lighting up, aren't. Out of all the lights, the ones that do light up are the TRICKLE light and the EFI light. I guess it's good that the CPU lights aren't lighting up, but what about the the GPU and POWER lights? Shouldn't those be lighting up too?I also tried booting up from a Snow Leopard disc (there isn't any internal CD/DVD drive [the previous owner removed it for whatever reason], so I've been using an external CD/DVD drive).
When I plugged in my Apple USB keyboard, I decided to press the caps lock key and see if it would light up green. No dice. I tried all 5 USB ports on the machine and none of them worked. But how did the CD/DVD drive work? It spun up when I turned the machine on. So since the keyboard can't be recognized I am unable to boot from a CD, or anything else for that matter.One more issue: there is no startup chime! Tried turning it off and on many different times trying some potential solutions out and not once was there a startup chime. I know for sure this is a huge issue.reconfiguring the RAM (which I inserted per Apple's instructions), resetting the SMC, resetting the PRAM (which wouldn't have worked anyways since the keyboard isn't recognized), and resetting the NVRAM (which, again, probably wouldn't have worked since the keyboard isn't recognized.)So here are my problems.

My 2008 aluminum MBP 15" is not letting the express card stay in. It won't stay and after search for answers to questions, want to open it and check out the express slot for myself. Done quite a bit of my own work before(Like replacing memory slots), but like to know what something is going to look like before going in.

My superdrive does not burn DVD's regardless of media or application. It fails every time. It reads but doesn't write. Firmware is up to date. I've used Toast, iDVD and Disk Utility. No luck. My AppleCare has expired so looking for an external DVD drive. Will the MacBook Air Superdrive work on my old MacBook Pro running 10.7.3?

I tried to update my Early 2008 white MacBook from OS X 10.5.8 to OS X 10.6. It seemed to be running well. It restarted and went to the white apple screen with the spinning wheel. I let it go for about two hours and nothing happened.

The indication light is on, but again, nothing on the screen. I have tried pulling out the battery, resetting everything i can reset, but still nothing.

My gf is using a white macbook 13'' early 2008 with the following specs:
2.4ghz intel core 2 duo
4gb ddr2 ram (667mhz)
WD 500GB 5400rpm
Mac OS X 10.6.8 Snow Leopard
switched on her macbook and then typed in her password (no caps and caps are not switched on either) and then hit login and then screen turn light blue for a few seconds and then i'm back at the login box again. Typed in password again, the same thing happened i tried resetting the passowrd through the installation disk of snow leopard(she only has 1 hardisk with her account, no partitions).And then it gave me a dialog box saying:Password Saved?The password you entered has been saved for the user xxxx. Resetting a user's password does not change the password for the user's login keychain so it will not be unlocked automatically.
Use Keychain Access to reset the password for the user's login keychain I have no idea what's the Keychain Access since i can't even get pass the login box. So i just click ok, restart the macbook and then entered the new password. And the same thing happened. Should i restore frm my TimeMachine or do a Repair Disk?

A few months back, my old reliable MacBook Pro (early 2008) started behaving oddly. Have no idea why, but went to start it up one day, and it took forever to start up and get me to the login screen. Been like that ever since. Occassionally, when I finally get to the login screen, the keyboard will not function. After a few minutes though, it always works. This only happens about 5% of the time. Once I log in, everything about the computer from a performance perspective seems to be pretty normal In addition to the slow start up, however, system gets extremely hot at the top of the keyboard, near the monitor. Fans run fast almost all the time when the system is powered on, and often when it is 'asleep'. CPU Temp goes to about 170, and the fans are always between 2400 and 3500.
I took it to Apple a while back, and based on the incredibly slow start up time they believed it was a disk issue. I went ahead and purchased a 500GB internal drive and this past weekend used SuperDuper to copy the original boot disk. All went well and I now have a new internal disk. At the same time, I upgrade the RAM from 2GB to 4GB.
After all that, the system is still very slow at startup and runs as hot as it did before. I will say, it does seem to be slightly faster on the startup, but not what I had become accustomed to for the first 4 years of use. I looked at the activity monitor and don't see any processes hogging resources. No anti-virus software running.Currently running Mac OSX 10.6.8 My battery is pretty muc shot, but I never really use the system unplugged.

I left my laptop on in my room while I went to the bathroom, and when I came out, I saw the message that told me I must restart the computer. The message froze the computer, so I shut it off by holding the power button and tried to turn it back on again, but it only boots to a black screen. I don't hear the loud hard drive noise, but I hear the fans. Without AC power but with the charged battery, the computer shuts down after a few seconds. The light on the button that opens the lid is dim-to-none when the lid is open and bright when the lid is closed.
I tried many troubleshooting methods discussed on this site, like removing and reseating the RAM and draining the battery, along with the things that the Apple website suggested, like resetting the SMC and PRAM, but nothing works.
I brought the computer into an Apple Store, and after the NVIDIA test was negative, the technician told me that the problem is most likely the logic board. I also took the computer into an Apple Authorized Service Provider, and the technician there said it could be the logic board, hard drive, or boot connector. He also said that there is a very slight chance that the graphics card could have caused the logic board to fail. He tried my computer with another battery and concluded that it's not the battery's fault.
The Apple Store is charging me about $330 for a flat-rate repair. Should I troubleshoot further using suggestions you may have or pay Apple for repairs? If I decide to have Apple repair my laptop, do I need to take it back into the store to pay the repair charges, or can I do it over the phone and mail the computer to Apple?

I recently just purchased one of the early 2008 Mac Pro Desktops, model number MA970LL/A and am trying to upgrade the video card in it. It comes standard with an ATI Radeon HD 2600 xt, and I would like to upgrade to an ATI Radeon HD 4870. I don't know that it will work though, I know that the NVIDEA that comes standard in the early 2009 Mac Pro does not work in the early 2008 Model. Does anyone have any information on this or know if that will work?

I tried restarting my MacBook (2.4GHz, 2GB RAM, 250GB HDD, early 2008 model) today. But when it turned back on it would just shut off and automatically try restarting. It did this over and over again until I just pulled the battery so it would stop. It wouldn't even let me do a force turn off. It would just start up, shut down, start up, shut down over and over again.

open the kext (Show Package Contents), then go to Contents, then open Info.plist (I usually open it in Property List Editor that comes with Xcode Tools (comes on the OS X Install discs). If it opens in Property List Editor, then do the following:
Go to IOKitPersonalities and open it On all the sections begining with WSTrackpad*3 (like WSTrackpadISO3) scroll down until you get "TrackpadThreeFingerDrag". Copy that line (it should have a tick next to it).

I'm at my wits end! My "9(" key works part time. (mostly NOT) There is absolutely no "rhyme or reason" to when it decides to work or not work! I have worked it, massaged it, banged on it, and even removed the key cap and blown it out with compressed air. No difference! Before I order a new keyboard ($84.95) and remove several dozen screws, I'm hoping someone has a "last ditch" technique to try. BTW: 17" MBPro/early 2008/2.6Mhz/OS10.5.6
