Early 2008 Mac Pro Won't Boot

I have an early 2008 mac pro that will not boot. Power turns on, power LED turns solid, but no display ever comes up and it never chimes. I have tried swapping out RAM, hard drives, disconnecting all peripherals... any other suggestions? Dead logic board?
... and yes, I was too dumb to buy the AppleCare. Stupidest move I have ever made...

Hi I think I have a similar problem.
My Mac Pro 8 core doesn't start up. When I turn it on here's what it does: the boot up sound > the grey/white screen with the apple logo and the little turning gear thing > then it freezes.
Sometimes after that the screen either goes blue with nothing but a mouse pointer that's moveable. but no login window. I can access the hardrive by network and weird enough it's booting on safe mode. I tried setting the SMC firmware but it didn't work. I took it to an apple store and when they plugged it into their displays it worked. When I brought it back, I plugged it into my Cinema Display 30" and the same problem started again. I reset the SMC firmware again and tried different displays I have at home but had the same problem. I plugged the 30" display into a Macbook Pro and it worked fine so I know that the display is not the problem. I've heard the the Nvidia 7300GT has caused problems but why would it work in the apple store? Any help out there?

  • Early 2008 mac pro won't boot from hdd when ssd is installed

    I have Mountain Lion 10.8.3 installed on my 1TB HDD in my early 2008 mac pro.  That is the only OS install on my mac.  I have an OWC SSD formatted but left as an empty drive that I am trying to use but when it's installed my mac hangs on the blank gray screen.
    My mac cold boots fine and runs fine when the SSD is *not* installed.  When I shut down and put the SSD into a drive bay the mac does seem to boot ok the first time, but when the computer is off for a while it will not boot.  It just hangs on the blank gray screen (no apple logo).    As soon as I pull out the SSD, the computer boots fine and runs fine again.  I am not trying to boot off the SSD, I am booting off the HDD.  The correct drive (1tb hdd) is selected in startup disk.
    OWC has been helping me and I have tested 3 SSD's.  So it does not appear to be a problem with their drive.
    The mac will boot into safe mode with the SSD installed.  It will boot if I choose the boot drive with the option key at startup.
    Mountain Lion was clean installed.
    Could it be some sort of library pref or cache issue?
    Any recommendations on what to try?

    A HT does not find a lot of errors.
    It doesn't look for bad sectors or directory or file problems.
    Clone your SSD now that you have a clean OS and has the Apple updates on it. Before you make changes.
    Install TRIM Enabler 2.2+ on it and any boot volume, to enable TRIM and so that Disk Utility's Repair Disk will trim cells. Mountain Lion Recovery won't  which is a shame, so...
    Clone and keep bootable backup clone of your system to use for maintenance.
    A really bad directory on a system drive will cause interference from booting.
    SSDs really need extra care, and even with TRIM, to be repaired from time to time and couple times a year, to do an erase and restore from a current image.
    Of course Mac OS system even iwth apps is small and doesn't need to have any data or media and fits on 120GB usually just fine and still have a good enough amount free so TRIM and Garbage Collection can work properly and not get low on free pages. But 20GB free should be the minimum free, and better to have more, at least whatever total amount is written out in a month.

  • Early 2008 Mac Pro won't boot after installing 2nd DVD drive

    All,
    I purchased a Pioneer DVR-117D from Mac Sales and after installing it in my new refurbished 2008 Mac Pro it won't boot. My MP will boot if I remove the drive. According to the Mac Sales website this drive should work fine in my MP. Any ideas as to why this is happening. I literally just got my MP today and installed the drive. Is it the drive or the Mac Pro. Thank you all.

    The drive was set to master, I switched it to CS before I left for work but haven't tried reinstalling it. I will try when I get back and let you know if it worked. Thank you again.

  • Early 2008 Mac Pro won't start.

    Early 2008 Mac Pro. Spelt some liquid on top that ran down front of computer. Tilted it back to wipe underneath and it shut down. Now it will not start. Processor fan runs full speed and that's it.

    Hello,
    My Friend spilt a drink on their laptop and the device started to smoke.
    My suggestion is to get a hair tight container fill it with rice and put your computer in it, and leave it for 1-2 days.
    The rice should absorb most of the water, and hopefully it should work again.
    If it does turn on make sure you check the lights under the keys!
    If they still don't work my suggestions are to take it in to an Apple store.
    Good Luck!
    I wish the best for your fellow Mac!

  • Radeon 5770 in 2008 Mac Pro, won't boot - hangs at Apple logo screen??

    Okay, so I had the Radeon 2600 XT and it kept giving me issues with pink & white checkerboards and freezing, then eventually wouldn't let me boot past the white/grey apple logo loading screen. Now, today I installed Apple Radeon 5770, just installed, got the MiniDisplay to DVI-D adapter and everything, but it STILL won't let me get past the white/grey apple screen! I can't seem to get the DVD drive to open either. Both of my hard drives have been working fine and I've even swapped slots and i still can't get past the white screen! What gives? I just dropped over $300 for this, so you can imagine my dismay and frustration. Can someone please help me with some ideas? Would be GREATLY appreciated.
    It's a 2008 Mac Pro dual 2.8Ghz (3,1), running 10.5.8
    M

    Yeah, ok thanks for the response about the screen! So, I don't have 10.6.5. I'm running 10.5.8, which the Radeon 5770 says it needs 10.6.5, but -finally- I got my computer to boot up with the 5770 in it, on 10.5. Al I did was hold OPTION+ Power button and it took me to a blue screen, then to my 500 GB new HD. I then switched over to my other username on Macintosh HD (drive that came with the MacPro) and OSX loads fine! I can tell that it still needs to be on 10.6.5, so I can download the drivers because the text is ever so slightly fuzzy, and the color isn't tuned well (too much contrast) and images take a little longer to load/ are a bit laggy. I'm just glad it's up and running! No more pink transparent checkerboards, and loud *** fan sounds! I am wondering though, what was causing this hold up? Is it only booting up because I have the 10.5.2 install disc in the SuperDrive? I almost don't want to take it out and try without it, after the trouble i've had, just in case lol.  I'd like to have an idea as to why, because I don't want to mask a problem, and have it eventually turn into a catastrophe.

  • Early 2008 MacBook Pro won't boot after Lion 10.7.1 update

    My 2.4 GHz 4GB RAM Early 2008 MacBook Pro wont boot after downloaded the Lion 10.7.1 upate. Upon restarting the screen went dead and now the system does not boot, as if the bootloader has been wiped out. Screen appears dead but was known to be working before hand. The hard drive spins up but doesn't sound like it is searching for data.
    Can anyone help me?

    Okay, I tried everything I can think of last night. I removed every startup process and every tool or programm that goes deeper into the system (GlimmerBlocker, LittleSnitch, Parallels). Cleaned Up every Cache I could find and refreshed every necessary Cache or Database possible. Took me a couple of hours. But still no luck - the machine doesn't boot, just in safe mode. Right now I copy all my personal stuff to a new external harddrive because TimeMachine doesn't work, after this I will do a clean install of Lion.
    It's not hardware related, it's the 10.7.1 update that doesn't work properly. By the way, the only errors remaining are:
    WindowServer - kCGErrorFailure
    ManagedClient - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
    SecurityAgent - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
    and a lot of:
    com.Apple.SecurityAgent.00000000-0000-0000-0000-0000000186A7: CoreAnimation: rendering error 506
    that's also the last one I get before the system hangs…

  • My Early 2008 MacBook Pro won't boot correctly

    alright so I have always wanted a macbook and I finally bought an early 2008 model from my friend due to he lack of cash to buy a newer one, so after a while it started booting slowly, like it would work but it would boot slowly, I tried to format it but I'd always get and error that said "could not validate source - error 254" any help on how I can fix this ? Ive run fsck multiple times and it tells me everything is ok, is there any other way to format my drive ? Oh and booting from the cd just gives me a folder with a question mark soooo yea any help would be appreciated, it runs mavericks and has been fine up until now

    The startup drive is failing, or there is some other internal hardware fault.
    Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
    Keeping your confidential data secure during hardware repair
    Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

  • Early 2008 Mac Pro - Can't load Boot Camp drivers for Win 7 64

    Trying to install Win 7 64 bit on my early 2008 Mac Pro.  I downloaded the Boot Camp drivers 4.0.4033 and installed them on a USB drive but, for some reason, when I try the install them during the process, I get a message that my hardware is not recognized.  Skipping the driver loading process, I am able to install Win 7 but when the system trys to restart to continue the install, I get a message "disk error, press any key to restart".  Pressing any key does not get me anywhere.  I went through the Win 7 repair process and again tried to load the drivers with no luck. 
    Any thoughts would be appreciated.
    Thank you,

    That article was also my starting point and I have followed those steps again and again and again. I haven't slept, I haven't done anything other then try to make it work for more hours than I can count. I came here for help because that solution is not working for me.
    The region and keyboard type settings simply don't have the Apple keyboard layout listed. As I said, someone on the Fusion forum tried to follow the article's instructions too and he managed to get it working because he COULD run setup.exe (Boot Camp Drivers) on his machine, and I CAN'T. Yes, it is all explained in that article... but the drivers WON'T INSTALL, I get an error message saying "This version of Boot Camp is not intended for this computer model".
    First you said it wasn't physically possible for me to install the drivers, then you said I should just follow the article. Well, the article clearly says "Install the Boot Camp Windows device drivers in the virtual machine" which you just said couldn't be done! I want to cry. I should have just bought a second laptop, this is too painful.

  • I have an early 2008 Mac Pro, which has re-booting problems. Also what does the spinning beach-ball indicate?

    Hi, I have an early 2008 Mac Pro which has re-booting problems.
    Processor speed is: 2.8
    Memory: 2GB 800 MHz DDR2 FB-DIMM
    2 x 28GHz Quad Core Intel Xeon
    I am running OSX Yosemite Version 10.10
    My Mac Pro keeps re-booting. Last year I had to replace my graphics card. My original card was the ATI Radeon HD 2600 XT 255MB, and that is what I have now. At this precise moment my Mac Pro is running perfectly, except that it is slow and the spinning beach-ball keeps appearing. I have managed to do some work with the disk utilities, verifying, cleaning and partitioning. Some errors were found and when it was cleaned this seemed to help my Mac Pro to function properly. Although I am able to use my Mac Pro now, from day to day I still experience re-boot problems. Also quite unexpectedly my mac dictionary has an error, it closed itself down and will not open at all, I had the message to say that a report will be sent to Apple.
    I have tried starting my computer with an external hard drive fitted via a USB cable, I use for back-ups. This worked and I was able to wipe my hard drive clear and replace all info from the back up I had done only a few days ago.
    This worked for a few days and then the same problem started again.
    I am beginning to wonder if I need to buy a new hard drive.
    If there is anyone who has some answers to help me solve my problem, I would be most grateful.
    Robert

  • With Boot Camp, should I install the 64 bit version of Windows 7 (Home Premium edition) OR the 32 bit version when installing onto an early 2008 Mac Pro operating OSX Lion with a 1 TByte internal HDD?

    With an early 2008 Mac Pro I'm about to add a second internal drive (1 TByte SATA) and initially install OSX Lion onto the new drive.  Then to partition this new HDD via Boot camp.  But my question is whether I am best advised to purchase the 64 bit version of Windows 7 (Home Premium) or the 32 bit version of Windows 7 (Home Premium) for the Windows sector of the disk  What are the differences, and will I notice a difference in performance?

    In chart from wiki, (scroll down to "Comparison chart") check the maximum CPUs supported.
    You don't see this on MSoft's 1st searched for chart hit. This is one reason you will regret not paying for Professional+ if you get Home Premium 64 as I did for Mac Pro early 2008.
    Home Prem Task Mgr sees 4 processors vs. the 8 that are seen by Pro+.    
    Costs more than a Mac upgrade to Lion if you make that mistake.

  • How do I fix my early 2008 mac pro boot hard disk. Lost everything when it crashed hard, can not reinstal via cd/dvd drive... are there any fix get it boot from dvd drive?

    I have an early 2008 MAC PRO Quad Core 3.0ghz processor. 8 Gig of rams, with a 1 Gig memory  Radeon 5770 HD Graphic Card running the latest Version of Snow Leopard OS.  Last week lighting struck the house take out all of my hard drives (4) thank god the surge protector mitigated the mother board from damaged, use the Parted Magic to check out the motherboard and it intact with no damage. I can boot with the Parted-magic and be able surf and post this question to this forums. I replaced a newly formatted hard  drive and trying to installed OS X Mountain Lions to the new drive, but unable to have it boot in my MAC PRO DVD, I get the usual chimes during the booting processed but the screen remain blackout, but able to boot with Parted-Magic to surf the web and access Apple sites/forums.
    I am not well verse in using the Parted_Magic to repair or get my-mac to boot normally so I can reinstall OS X. Any help would appreciated.
    Thank you
    Disabled Veteran. 

    Go to System Profile and look, does it say "MacPro3,1"?
    That is 2008.
    FBDIMM would be 800MHz. Did you use older slower 667MHz in yours?
    You can but take a hit in performance.
    Sounds like MacPro1,1.
    Mac Pro (3.0GHz quad core (dual CPUs) 8GB 667 RAM)
    In 2007 March an 8-core 3GHz did come out 2,1.
    So just to be clear.
    ===========
    It was all working fine a couple of days ago. At the time it randomly shut down I was trying to use Boot Camp to create a Windows 7 area,
    Whenever you want to install Windows, remove all the drives other than the one Windows goes to. And if you use a dedicated drive YOU DO NOT NEED Boot Camp Assist, unless you use XP, which really is limited and crippled (one processor, 1.9GB RAM support).
    And when it freezes, your only choice is to nuke (reformat) and restore or get out that backup CLONE you made before (ie, Step #1 in the Boot Camp Guide).
    Sure that whole NTFS / MBR / GUID could be an issue, but you should just have a blank drive or clone.
    No don't bother Apple, they seem to not have a good sense about Windows on Mac Pro anyway.
    Other than zap pram from cold boot / tried booting with NO drives inside and just 10.6. DVD - should be fine.
    You should be fine iwth Windows 7 DVD and one drive, or even XP.
    Make sure you take your time and reconnect cards etc properly and any cables.
    Booting from OS X DVDs may not work if there is a drive with a totally shot directory or partition table. Put them in FW case and turn on AFTER OS X is booted.

  • Installing OS and Apps on SSD boot drive on early 2008 Mac Pro while keeping all other data from old iMac on hdd

    So I've just got myself a early 2008 Mac Pro with a OCZ RevoDrive 80GB PCIe SSD to replace my old iMac which is slowly but surely giving up on me. I want to put my OS (mavericks) and some/all (whichever is possible/easier) apps, both apple and 3rd party, from my old iMac, onto the SSD but keep all my other data on the 2TB HDD, also from my old iMac, in the mac pro. Can anyone tell me how to do this/if its possible? (not massively tech savvy so simpleish language and steps would be handy!) Thanks!

    How to use an SSD with your HDD
    If you are going to use an SSD as a boot drive together with your existing HDD as the "data" drive, here's what you can do.
    After installing the SSD you will need to partition and format the SSD using Disk Utility. Then, install OS X on the SSD. After OS X has been installed boot from the SSD. Use Startup Disk preferences to set the SSD as the startup volume.
    Open Users & Groups preferences. Click on the lock icon and authenticate. CTRL- or RIGHT-click on your user account listing in the sidebar and select Advanced Options from the context menu. You will see a field labeled "Home dir:" At the right end you will see a Change button. Click on it. In the file dialog locate the Home folder now located on the HDD (HDD/Users/account_name/.) Select the folder, click on Open button. Restart the computer as directed.
    When the computer boots up it will now be using the Home folder located on the HDD.
    Another more technical method involving the Terminal and aliases is discussed in depth here: Using OS X with an SSD plus HDD setup - Matt Gemmell. This is my preferred approach because I can select which of the Home's folders I want on the HDD and which I don't want. For example, I like to keep the Documents and Library folders on the SSD because I access their content frequently.
    Be sure you retain the fully bootable system on your HDD in case you ever need it.

  • Early 2008 Mac Pro + nVidia 8800: Never going to work?

    This forum is littered with threads about early 2008 Mac Pros with the nVidia 8800 card - none of them positive.
    I was unfortunate enough to wait for Apple to release such a machine and buy it. Graphics performance is dire given the hardware available. The machine routinely crashes with the window manager hang problem (the user interface just locks up, yet network services etc. still work), in the way familiar to anyone blighted by this particular bug; just run the Folding@Home client on your machine if you want to experience the joy. Or screensavers, sometimes, so I've had to turn those off. And I've had to turn off monitor power saving too, because I too suffer from the 'monitors sometimes don't wake up' bug. And of course I can't sleep the machine either, because firmware upgrade or not, it's still not reliable. And after all this, still the machine crashes.
    SSH to the machine; try to restart cleanly; even 'sudo reboot' won't restart it. Apple have achieved something I've never seen out of any Unix or Unix-like operating system, ever; the kernel is unable to kill its own processes.
    There have been no indications from Apple that I've seen on these forums over several weeks that the problem is even being acknowledged, let alone tackled. Latest reports indicate that even the 1st gen Mac Pro owners are suffering if they install the 8800.
    http://discussions.apple.com/thread.jspa?threadID=1460752&tstart=0
    My machine rarely makes it through the day without a forced reboot due to the window manager hanging. I can't do any work on it. I can't rely on it. I can't enjoy it. I can't even use it for web browsing without fear of it hanging.
    There seem to be no facts about this at all. So all I can ask for is opinions. Does anyone have any offering of hope that early 2008 Mac Pros might ever work properly with 8800 cards? Y'know, little things, like actually being able to handle graphics? Or sleeping the monitors? Or, heaven forbid, sleeping the whole machine? Or should I just send it back as unfit for purpose?
    Yours, tired and exasperated... :-/

    I posted this in some other blog (forum), I should have posted this here also but I hope this gives you and all with these problems hope!! I also ran some fish tank test some else posted to get the folding problem to happen and I can not get it to happen at all now, and since my 8800 went in I get NO LOCKUPS, SCREEN FREEZES, shaky blurry video when I boot, so far NOTHING, IT JUST WORKS!!!!!!!!
    Now that I think about it the person who said to use the fish tank program had a bad 8800 and maybe you do also!! here is the link to that:
    http://discussions.apple.com/thread.jspa?messageID=6965475&#6965475
    I purchased my first mac pro early 08 2 months ago (amazon.com).
    2 quad core 2.8's, 2 gig apple 4 gig OWC total 6 gig ram,2-WD raptors (1st mac 2nd boot camp winxp 32 bit), apple care.
    I had all my problems with the ATI card (I always purchased ATI, never Nvidia, for all the PC's I built) a couple of times I bought the first ones out, these had all kinds of problems until good drivers that actually worked were released (usually 6-12 months after the release of the card).
    So I try not to buy routers, graphic cards, etc.. for at least 6-12 months, but back to my 2600 card!!
    When I received my mac the graphics would freeze, I did a lot of online reading only to find out the ATI 2600 was the problem, the cure was to hook up 2 monitors to the card (and that worked!!).
    Then they came out with the firmware update, now my main monitor would after 2 days on a reboot be scambled (samsung syncmaster 213t, NEVER had ANY problem with it before on any PC I had, so I knew it was not the monitor) to fix the problem I had to either turn power off to the syncmaster or resetting PRAM (worked for a couple more days, then the same problem).
    I called apple and they sent a tech out within days to replace the ATI card, the replacement did the same thing after a couple of days, so I called Apple back and they took a bunch of info from my computer (BTW not much at all loaded in the mac side) and said to call back in a week, so I called back a week later and they said they were going to exchange the card for either another ati 2600 or the Nvidia 8800, I said 8800 and a day later on a saturday I received it, swapped the card and NEVER HAD ANY PROBLEMS at all!!
    So I don't know if the ATI card has problems with certain monitors or they are just poorly made (maybe AMD is mad with Apple that Apple did not use AMD processors).
    I have read others that swapped with the 8800 and their problems went away also!!!!
    Maybe some have no problems with the 2600, but I would not recommend it to anyone, if you can avoid the 2600 GO WITH THE 8800, the drivers will get better (and the 8800 will eventually outperform the ATI)and you will not be sorry.
    Apple is awesome, they are 2nd to none, their is no other company like this anymore that I have dealt with in a long time (not just because they gave me a 8800), like I said in the beginning of this post I always purchased ATI cards and would have kept it if it would have worked but 2 doing the same, ATI [AMD] has lost my support until they prove otherwise.
    I recommend Mac's to everyone now!!
    good luck and let me know it any of this has helped!!!!!!!!!!

  • Will OSX support Adaptec PCI Express scsi cards in an early 2008 Mac Pro?

    I need to move my scsi interface scanner from a G4 machine and the old PCI Adaptec AHA 2930 CU card won't fit.  I was using Snow Leopard on the G4 unit - it still supported the Adaptec card and all was good.  My 23" Cinema display then bit the dust and I replaced it with with a 24" Cinema display with the mini display port connector.  I purchased an adapter from Kanex to make it compatible, but the adapter was defective - so I returned it.  Their reviews aren't very good - seem to have a lot of D.O.A. adapters - not sure I want to deal with the frustration, but it would be the least expensive option.
    I do have, however, an early 2008 Mac Pro that I can use, provided that it supports the newer PCI Express scsi cards that Adaptec makes.  I'm not sure which one to get yet, either.  I'd rather not buy one and find out it won't work.  I can make a partition on the boot drive for Snow Leopard in case scsi isn't supported in later versions of OSX.  In case you're wondering, I did use a scsi to firewire adapter to run the scanner on my laptop for a while - but it stopped working and I can't locate any replacements (or the company - 2nd Wave Technologies - for that matter).  I haven't tried locating a scsi to usb adapter, but from what I can see, they are getting pretty scarce.  I'd replace the scanner, but it is fairly pricey and the newest model retails at the price of a small car - so that really isn't an option at this point.
    Thanks in advance for any info.
    Message was edited by: Jakob Richardt
    Changed name of display adapter manufacturer.

    Thanks for the response - I guess the question I should have asked is "Will OSX support scsi cards in an early 2008 Mac Pro and if so, which ones?"  I didn't realize Apple and Adaptec weren't working together - my G4 tower arrived with an Adaptec card in it when I bought it in 2000 (from a third party vendor, not directly from Apple).  It came with either OS 8.* or OS 9.  When I updated to OSX, everything continued working, so I didn't think much about it until I pondered using the Mac Pro for the scanner - at some point the G4 is going to stop working - need to have a solution before that happens.  The manuals I've been reading refer to the slots in the G4 machines as PCI.  The manual for the Mac Pro refers to the slots as PCI e.  These slots have fewer connectors, so I thought that the "Express" part of the name referred to this particular card configuration when compared to the longer card connectors in the G4 type of machines.
    Can you tell me what scsi card brands will work in the Mac Pro?  I'd still like to pursue this option.  As I mentioned in my original post, buying a new scanner isn't in the cards right now - it costs more than the computer, so, although pricey, the card option is still less expensive.
    Thanks!

  • Early 2008 Mac Pro 3,1 Mystery Logic Board/GPU Issue

    I recently received an Early 2008 Mac Pro 3,1 for free because the owner couldn't figure out what was wrong with it. It would boot up with the startup chime, but never output any video, and kept rebooting and replaying the startup chime.  Using the diagnostic LEDs on the logic board, I was able to see that the Power Good LED (LED 7) and the EFI LED (LED 9) were both on, but the GPU LED (LED 8) never lit up.  After trying all the PCI slots and confirming that the graphics card worked in another Mac Pro, I confirmed it wasn't the graphics card.  I then tried a different power supply and different power supply cables, different RAM, different RAM boards, but still nothing.  (Note: I also went through all the usual stuff: Power Cycling, PRAM, SMC Reset)
    I then ordered a replacement logic board (used from eBay) and spent the weekend swapping out the logic board.  After the swap, the Mac Pro STILL won't output video, and now the EFI LED (LED 9) won't even light up.  Tried resetting the EFI Firmware via a CD, and still nothing.  Does anyone have any idea as to what the issue could be?  I'm 95% certain I plugged everything back in correctly on the board, but I don't know what else to do other than tear it apart again to confirm everything is plugged in.  The only other thing I can think of is that the second logic board I received was also bad.
    Please help!!!

    Your problem sounds like a graphics card problem to me.
    confirming that the graphics card worked in another Mac Pro,
    Was this also a Mac Pro 2008 model? was it running the same Mac OS X version as you are testing? what version?
    what graphics card are you trying to use? Genuine Apple or flashed PC or unflashed PC? what Mac OS X version?
    That second board sounds Bad to me if it won't say EFI-OK.
