Mac Pro early 2008 power off suddenly alone and gives a long beep on startup

Hello everyone! Can you resolve the problem reported? I have 6 equipaments identical to those with the same problem, some worse than others, and only two barely functioning, others are stopped. They power normally and suddenly alone they power off , and after that I only can power on again , after hours waiting or only the next day , and when it's power on , on startup , they give me a long beep , before the chime , then I can work for a time (minutes or long time , it's not secure)
I talked with Apple Computer (from USA) and they do not assume that the problem exists and that many users have the same problem, worldwide.
If you're not satisfied with the result of Apple, we will have to press them to assume the defect and promote a recall on these equipments. We have many users with the same issue (MacPro off alone)

All places where I have my equipments (they are in 4 different places, but I have tested them in all four locations), are electrically grounded, the electrical networkstabilized, reviewed annually and I use UPS minimum of 1.5 KVA (I have two UPS of 3.75 KVA) . I tested with the original HDD , with all the applications that I use installed , only with the system installed and the same procedure on a new HDD and got the same result . So , it is not eletrical problem . I have iMacs , MacBooks , G5 and MacPro early 2009 working in the same places with no problems . I tested all the sites with three different electricians and all
approved my Electric networks . As I know, all Apple equipment have
surge protection, precisely to prevent thecomponents from being damaged
by electrical problems. Again , it is not eletrical problem .

  • Hello. My mac pro early 2008 restarts after sleep mode and it works slower. I tested it with apple hardwear test and it seems to be ok. Thank you.

    Hello. My mac pro early 2008 restarts after sleep mode and it works slower. I tested it with apple hardwear test and it seems to be ok. Thank you.

    Try this:
    clone your system and repair it with Disk Warrior instead
    Or try a clean test system install on another drive
    A must: SmcFanControl 2.2 - a mere 400 rpm extra to keep air cooling up
    Try to run w/o externals. MyBook included.
    Is that a 7200.11 1TB? they had a lot of issues.
    Run AHT off your OEM DVD.
    2008 had to have EFI and SMC updates to deal with freezes on wake from sleep, and like all models, high inrush current.  Hopefully you have a UPS and is 1500VA unit.
    When you do hard restart from power button, you almost certainly add more directory errors and to files requiring immediate attention to repair and rebuild the directory; and to scan and repair and delete cache and temp files and folders. A must. Invest in bootable backups SuperDuper along with Disk Warrior (or TechTool Pro 6, maybe Drive Genius 3 but I'd rate that #3).
    TimeMachine has its own bad habits, especially with Green drives and some externals.
    Try to rule out everything and then add back one at a time.
    And it may just be time to replace the 8800, very common, a couple threads this week, and it is 3 yrs old.  Might want ATI 5870 or 5770.

  • Mac Pro (early 2008) shuts off randomly, suspect PSU runs too hot.

    I know there have been other posts on this, but it seems no-one mentions how hot things are running or ever provides any details.
    History.  Mac was brought in during its last week of Applecare for the issue of random power offs.  Not errors or kernel panics.  Just powers off like you yanked the plug, there is a loud click which sounds like a muffled static shock.  Sometimes the issue would repeat time after time unless you let the mac sit.  On other days it never happened. The issue can easily be replicated by setting the mac to never sleep, and letting it idle overnight.  Invariably when you come back to the mac in the morning it'll be powered off.
    The mac was brought in under applecare and repaired for a "faulty video card" that was causing the issue. It took apple a week to repair the mac, during which the Applecare warrenty expired.
    Two weeks after the repair the issue happened again.  The mac simply shut off on its own, no error or anything in the console logs.  Again, like you had pulled the power plug.
    I contacted the apple store who did the repair and fought with them to have them look at the mac again.  I even gave them specific instructions on how to repair it.  Yet I could get nothing from Apple and that upsets me. Apple won't even honor their own work.
    ****** off I let the mac sit for months.  However I had a photoproject I had to do and low and behold the SAME issue is happening still.
    So here are the specs, just from the mac sitting idle while I type this post and do some other web browsing. (amazingly enough its been stable today.
    MacPro:~ william$ uptime
    15:28  up  1:10, 2 users, load averages: 0.04 0.08 0.09
    MacPro:~ william$
    Temps are in the 80's to 90's F for CPU, Mem, Hds...etc.
    However what seems odd to me and I did note this when I submitted the mac to apple for repair that the PSU seems to be awefully hot compared to the rest of it.  The PSU temp sensors report 170* and 150* on average at idle.  Often climbing to 200*F plus during consistant heavy loads.  The PSU fan at idle reports 750rpm on average as well.
    I suspect its a power supply issue for the shear fact that it shuts off so randomly and quickly.  If there are any apple technicians who read this I'll gladly send you the case #, but as of this moment I don't think I'll be purchasing another Mac, I don't even know if I want to pay out of my own pocket when I paid Apple for a warranty that they won't even support their own labor and parts on.
    If  were to walk away from this mac within the next 24hrs it would simply shutoff like it ran out of power on its own despite being set to never sleep, nor having any scheduled shutdowns.
    How hot shoud the PSU be idling? It seems that 170* is a tad hot for a PSU at idle.  Howe fast should the PSU fan spin on average vs temp?

    I am having a similar issue with my 2008 model Mac Pro. I believe it is partly an underfed power supply or even loose circuitry in the box. My boyfriend and I brought the CPU from my office to my house this past weekend so we could use my flatscreen TV as the monitor for the unit and both look at our business projects as well as watch movies through the unit. (It takes a lot of effort to move this thing. It is very heavy!) It seemed to work fine for about half an hour, then the Mac Pro shut itself off. When we got it started again, I had to reach behind it to attach the sound line output, but the unit shut off immediately when I bumped the power cord.
    Are these two separate problems (i.e. overheating and random shutdown + loose wiring/input mount for power supply) or are they related? From the above post by thirdgen89gta, it looks like the shutdown problem is not isolated.
    Does anyone have any experience or suggestions for how to fix this?

  • Mac Pro Early 2008 Power Up Issue

    Hey Everyone,
    This is my first post so please excuse my ignorance on the process. 
    Anywho, so my problem is this.  I have an Early 2008 Mac Pro, that when it is on it runs great.  My biggest issue is that I installed the ATI RADEON 5770 and installed lion on the same day.  Ever since that day the computer has issues with powering on.  Basically what happens is I hit the power button, nothing happens, then I pull the power cord, plug it back in, and the computer starts up with zero issues.
    Any idea what the cause could be?
    If not I am just going to bring it in and pay for it to be fixed, but wanted to check with you guys first.

    What are you trying to run with?
    Two 5870s? something else?
    there are only the two 6-pin aux connectors. It isn't built for 8-pin or 4 x 6.
    You can add/stuff a PSU 450W into optical bay, you can find 6-pin splitter and as long as you don't OD.
    I assume 8800/4870 or something and now want ????

  • Mac Pro (Early 2008) Power

    I need at least 3 6 pins to power a card, but it seems that there are only 2? Is there a 3rd one somewhere that I can't visibly see (or even unplug one of the fans) or am I out of luck with my Mac Pro?

  • Mac Pro (early 2008) cannot startup

    Today, I shut down my Mac Pro (early 2008) for about two hours and now it just refuses to startup.
    This is the symptom:
    Power-on LED illuminates when power button is pressed and fans spin continuously but there is no boot tone or video
    Apple Service Guide
    1. Reseat video card. (Make sure video card is fully inserted in connector and end of card is 1. secured by the connector latch.) For video cards that require power cables, check that they are connected.
    I have two GPUs. NVidia GeForce 8800 GT and NVidia GeForce GT120. Tried them individually. Cards' fans spinning.  Check diagnostic LED and LED 7 & 8 no light. Only LED 2 Yellow and LED 9 Green.
    2. Verify speaker cable is fully seated.
    No idea where this is.
    3. Reset logic board. Refer to “Resetting the Logic Board” in this chapter.
    Same symptom. LED 7 & 8 no light. Only LED 2 Yellow and LED 9 Green.
    4. Check diagnostic LED 3 and/or LED 4 for processor connection.
    Off.
    5. If only one of the CPU Error LEDs (LED 3 or 4) comes on, try swapping the processors. If the Error LED follows the processor to the other processor location, replace that processor.
    Since LED 3 & 4 are off, I guess CPUs are fine.
    6. Replace logic board
    This seems to be a standard fix suggestion for all startup failures in the service guide. Anyway, to check if it's a logic board issue?
    I tried this too:
    System Reset
    Mac Pro (Early 2008) has a system reset switch on the logic board that may be used to restart the system while it is powered up. This switch can be used to determine if a computer that won’t consistently boot from a cold start has power supply issues. Follow these steps to reset the system:
    1. With the computer powered up, press the SYS_RST switch located in the upper right-hand corner of the logic board. To press the switch, use the nylon probe tool (Apple part number 922-5065).
    2. If the computer boots after you press the SYS_RST switch, try shutting the computer off and restarting by pressing the front power button. If the computer restarts when you press the SYS_RST switch but not from a cold start, the power supply may need to be replaced.
    and I experienced 1. Can conclude not power supply issue? Did diagnostic check and still the same LED 7 & 8 no light. Only LED 2 Yellow and LED 9 Green.
    I checked both memory riser cards. No red light. Half a year ago, I experienced the same no chime startup issue and found that Apple's supplied DIMMs were the culprits. I tested individual DIMM and still no go.
    At loss now.
    Apart from sending in for repair, no budget for that, and other steps to revive my Mac Pro?

    had this exact problem yesterday. this is how i solved it although im no apple genius
    My Mac pro 3,1 simply woudlnt boot normally no matter how i tried to reset it. power light was fine, no ram errors, just no chime and no video.
    how i fixed it:
    1. shut down and unplug
    2. open side case (you should be using an antistatic wrist strap if you do this)
    3. unplug EVERYTHING. (remove all 4 HDDs, video cards, Ram boards, power cable, USB cable, audio1/8" jack, firewire cables. leterally you want it bare bones. only thing i left in was my superdrives)
    4. i removed the logic board battery and while unplugged held the power button for 1 min to drain all capacitors on the board. left it unplugged for 10-15min after this
    5. after 15 mins, the only things i put back were the logic board battery, ram boards, the audio jack to check for a boot chime, and the power cable. ( no video cards, no hard drives, not even the boot drive, no keyboard etc.)
    6. press power button to boot. HOPEFULLY you head a chime. if you do, hold power button to power off system.
    7. now only insert the boot drive and one video card into pci slot one (power plug should be out to install things)
    8. start the computer back up and look for video. hopefully it asks for a keybaord and mouse on the screen
    9. shut down without reinserting keybaord, mouse, or anything else.
    10. unplug system after power off, and reinstall and plug back in EVERYTHING
    11. reboot and hopefully all is well????

  • Mac Pro Early 2008 will not boot off Win7 Install DVD

    Hello,
    I am hoping someone out there will have encountered something similar and have some suggestions or ideas, because at this point I can't think of anything else to try.
    I have a 2.8 Ghz 8-core Mac Pro (Early 2008) with an Nvidia 8800GT Graphics card. I am running OS 10.6.2, fully patched and updated.
    I am attempting to install Windows 7 Ultimate via Boot Camp, and am encountering a rather odd problem.
    Once I have launched Boot Camp Assistant it allows me to partition the drive and does so correctly, but when it attempts to reboot off the Windows 7 installation DVD, I encounter a blank grey-white screen similar to that which you normally get on startup but without the Apple logo. This continues for some time (it seems to vary), and then the screen goes dark and the monitor says it is receiving no signal. The fans on the Mac Pro go for a while, then it goes to sleep. I've tried leaving it for a couple hours, no dice.
    I've tried both the 32-bit and 64-bit Windows install disks. I had the release candidate for Windows 7 installed previously, and it worked perfectly. I have since tried that same install DVD that I used to install the release candidate, and it encounters the exact same issue. Booting up off the Snow Leopard Install DVD works fine.
    I tried doing a clean install of Snow Leopard on a spare drive, booting off that, and then starting from square 1 using Boot Camp Assistant to re-partition that same drive. Same problem. No matter what I do or try, my Mac Pro does not want to boot off this install disc. I have yet to try the disc in another machine to see if it works there, and I will as soon as I can, but the fact that the RC disc worked a few months back and now will not seems to rule out the boot discs as defective. I've also tried both my internal optical drives with no change, and no other discs have any issues.
    I've already spent an hour and a half talking to Apple Technical Support, and they seemed stumped, so I'm hoping someone will have a notion. If not, I understand and appreciate you taking the time to read this- I have no idea at this point, and I'm generally a pretty knowledgeable user.
    - Andrew

    Thank you for your reply,
    Pull all the drives you have other than the one that you will install Windows 7 to.
    I think I will try this next.
    Don't put Windows 7 on the same drive as OS X, give it its own.
    That was initially what I started out doing.
    And you don't even need Boot Camp Assistant.
    True, but it's what Apple suggests using.
    Might also want to try moving the monitor cable to the other card port.
    Hmm, I think I'll try that.
    Any other PCI cards or devices attached or installed should also be questioned or disconnected.
    I've disconnected everything I could.
    Always a good idea to start fresh which I assume you are doing (not trying to upgrade over RC etc).
    Yes, the drive was empty to start with.
    Honestly it seems like the Mac Pro is generally refusing to boot from any Windows disc. Things I've tried since my initial post:
    - Loaded Windows 7 Install disc into my room mate's windows PC... loaded up fine, got to install screen
    - Tried his OEM copy of Windows Vista 32-bit, same issue
    At this point it seems like maybe some kind of firmware issue or some kind or graphics driver issue, but I'm pretty much grasping at straws at this point. It doesn't seem like it's even getting to the point where hard drives or anything matters.
    It does recognize that I have a Windows 7 install disc inserted when I use the boot selector/startup disk chooser.
    Thanks for the ideas, I'll try those out and see if any of them help,
    -Andrew

    Try this:
    clone your system and repair it with Disk Warrior instead
    Or try a clean test system install on another drive
    A must: SmcFanControl 2.2 - a mere 400 rpm extra to keep air cooling up
    Try to run w/o externals. MyBook included.
    Is that a 7200.11 1TB? they had a lot of issues.
    Run AHT off your OEM DVD.
    2008 had to have EFI and SMC updates to deal with freezes on wake from sleep, and like all models, high inrush current.  Hopefully you have a UPS and is 1500VA unit.
    When you do hard restart from power button, you almost certainly add more directory errors and to files requiring immediate attention to repair and rebuild the directory; and to scan and repair and delete cache and temp files and folders. A must. Invest in bootable backups SuperDuper along with Disk Warrior (or TechTool Pro 6, maybe Drive Genius 3 but I'd rate that #3).
    TimeMachine has its own bad habits, especially with Green drives and some externals.
    Try to rule out everything and then add back one at a time.
    And it may just be time to replace the 8800, very common, a couple threads this week, and it is 3 yrs old.  Might want ATI 5870 or 5770.

  • Black Screen for Install of Windows 7 on Mac Pro Early 2008

    I have a mac pro early 2008 with lion 10.7.4 and boot camp 4.0.3 I think... anyways the problem I have is when I am in boot camp, and configure the HDD partition, then the machine reboots... when it reboots and starts up boot from the install DVD (legit retail copy) I just get a black screen on both monitors. No curser, nothing just a black screen, same as I get when the machine is off! the little white LED lights are on and nothing...
    I can hear the DVD spinning up and down a few times then that just stops too...
    I have tried resetting the PRAM, pulling the power and watch battery inside for a few minutes, I tried the "fix" that is online for the imac problem with the answerfile and got no different resutls with anything, still the same probelm.
    I have the OEM ATI Radeon video card 512MB.
    * as a side note, I was never able to download the windows support drivers prior to trying the install... I tried and tried for the last two days so this time I "unchekced" that box and just went for the install...
    Any help will be greatly appriciated, thank you :-)

  • Mac Pro (Early 2008) shuts down unexpectedly

    I have a recurring problem with my Mac Pro (Early 2008). I put the computer to sleep; then, when I tap a few keys on the keyboard to wake it up, I hear the start-up sound and it boots up as if it were shut down.
    This is particularly strange, because I do not have to use the "power" button on the tower to turn it on. When I tap the keys on the keyboard, as if to wake it from sleep, it makes the start-up sound and boots. I am guessing that somehow it is shutting off when I first try to wake it from sleep, and then must re-boot. But this is odd behavior that I've never seen from any Mac, and I've been using them for almost 20 years.
    Any ideas? I'm going to call Apple Support but I always dread those long wait times and often fruitless conversations. I did not migrate information from my previous system; I took the time to manually migrate my files and reinstalled all apps from DVD specifically to avoid problems like this. Very frustrating.

    I've noticed the same problem for one day with my new MP 2.8 dualquad, got a reboot after every sleep.
    This solved the issue for me:
    • Reset the PRAM (Boot the machine and hold ALTCOMMAND+PR for 3 startup gongs)
    • Reset the SMC -> http://docs.info.apple.com/article.html?artnum=304123-en
    Good luck

  • Mac Pro (Early 2008) freezes, reboots to recovery system, trouble locating startup disk

    I have two issues which may or may not be related with my Mac Pro.  First, off and on for several months is has been frozen when waking from sleep.  I can hit a key and see my desktop with the windows I left open, but I get the spinning beach ball and the time is typically several hours behind.  The only way I can get it to start is to restart from the power button.  This typically happens overnight when my computer has been asleep for a long time.  Sometimes I hear the fan run while the computer is asleep and I don't know if that is related. I've tried switching from Firefox to Chrome to see if that was the problem since I typically have a few tabs open on Firefox when it freezes, but that does not solve the problem.  The next step I plan to try is to get a can of compressed air and clean the fan and check if the video card air intake might be clogged, based on information I have read in various forums.  Does anyone have other suggestions for things to try to eliminate the freezing?  Another suggestion I read was to get a new logic board battery installed but I hate to lug this thing into an Apple store unless I really have to.  Most of the time I'm comfortable fixing things on my own.
    The second issue is that when I reboot after shutting down the computer with the power button, it does not always load the startup disk.  Sometimes I get the recovery system instead, and if I try disk repair, restore from backup, or the startup disk option from the apple menu, it cannot locate the startup disk.  Usually after a few tries, I can restart it and get my desktop, but I'm not sure how long that will work.  I hoped that resetting the NVRAM would take care of this but it has not fixed the issue.  When I do disk repair, it says the drive is fine.  I've also used idefrag to clean up the drive.  I'm thinking my hard drive might be about to die and I should just get a new one, but I don't want to spend the money if that is not the issue.  I have 83 GB free on the drive so space should not be an issue.
    Any suggestions on fixing either or both of these issue would be very much welcome!  I need to make this computer last at least a couple more years.

  • Mac Pro Early 2008 not booting

    Hey guys!
    I walked into a problem with a Mac Pro early 2008 model.
    I got this Mac Pro from somebody since it wasn't working anymore. I was told there could be a graphic card (Nvidia) issue which I think should at least be correct but I am also having trouble with loading EFI. The following things happen:
    When I turn on the mac using a DVI to VGA adapter i have no screen at all. (I don't have any other options atm)
    There is no HD inserted.
    PRAM and SMC reset won't do anything, i'm not even sure it reads keyboard commands.
    The fans all work even the one on the GPU.
    Front LED just burns steady.
    No lights on my USB (non Apple) Keyboard turn on.
    The lights of the mouse just flashes on start up.
    RAM LEDS light up on startup.
    Motherboard reset button doesn't make anything change.
    When I Press the button for the diag LED's, the Trickle Power and the Good Power led come on, the GPU LED stays off. The EFI LED is off aswel.
    No RAM errors show up. Tried switching RAM and disconnecting RAM and GPU.
    No startup chime what so ever.
    I figured there could be something wrong with the EFI firmware (or logic board is just broken). I am trying to restore the firmware with a firmware restoration cd, but I can't get the cd tray to open. I pressed the on button and kept pressing it for a long time. All it does is makes my status LED flash a couple of times real fast, but then it goes back to normal state. No cd tray is opening and its not flashing 3 times fast, 3 time slow, 3 times fast as it probely should be doing.
    You guys have any idea what to try next or how to restore the firmware?
    Thanks in advance.

    there's a boot code to run with the older machines
    Pike wrote this code
    Using this code will get you around the efi/boot issue and move on to OS 10.10.02
    Installing Yosemite just prior to entering the efi/boot, then restart twice.
    You'll need to research Pike's code, but your 2006 to 2008 machines are long ways from trash.
    I'm upgrading my 2006 to 8 cores, Yosemite and 32 gig of ram.
    Long live these early Mac Pros

  • Mac Pro (Early 2008), Tiger Boot

    Is my Mac Pro (Early 2008) able to boot from Tiger normally? I 've tried many times but it seems that Tiger has not the necessary drivers for my ATI Radeon HD 2600 Pro! Boots, but there is no communication with my graphics card. Is there any way to make it work?
    I' ve tried to install Tiger from the DVDs of my MacBook Pro, MacBook and from the DVDs of a friend's previous generation Mac Pro, but not from a Retail Tiger DVD... Do you think that this is my problem?

    The only hack is to find a system with 2600M it sounds like.
    Or get X1900 that works in 10.4.11 and 10.5.x
    Cloned system and then reapply the combo update would do if you do have an Intel Tiger system.
    I've been using Vista x64 since late '06, before it was RTM forward, and the horror stories of trying to get it to run on some motherboards, BIOS, etc - I have more respect for what people are willing to go through, how different it is on Mac Pro, and the way OS X is tighter controlled to hardware... but it does make for problems.
    People held off buying Mac Pro until CS3. And now some are considering buying ref'd units just to run Tiger or wait 3-6 months for things to catch up.
    Game developers love 8-cores, cuts down time to compile, test and develop, and will pay dividends down the road in games that unless the power, but most, a lot, of applications really have trouble using more than 4-cores, it is a technical challenge and requires new compilers and tools.
    ATI and Apple aren't likely to build any new drivers for Tiger

  • ESata card for Mac Pro (Early 2008)

    I am looking for another two port eSata card for my Mac Pro (Early 2008) model. The card I ordered before Christmas from Amazon (UK) has just arrived but doesn't fit (Lacie eSATA PCI CARD)
    http://www.amazon.co.uk/LaCie-130823-eSATA-PCI-Card/dp/B001O9KEKM/ref=sr11?ie=UTF8&qid=1294318895&sr=8-1
    It's only for two drives I use from time to time to back up my HD Video (personal family stuff only).
    Any recommendations?
    Many thanks, Matt

    I have the Sonnet E2P in my Mac Pro Early 2008. Also available in UK from here:
    http://www.macupgrades.co.uk/store/productinfo.php?productsid=421
    And "Yes": that arrangement is the PCI-Express card connector - that's what you need.
    !http://www.macupgrades.co.uk/store/images/381-img-main.jpg!
    It's definitely a Mac card - Sonnet product page here has latest drivers, etc.:
    http://www.sonnettech.com/product/temposatae2p.html
    (Currently = v 1.2.5)
    Edit: you could always use one of these:
    http://www.macupgrades.co.uk/store/productinfo.php?productsid=511
    !http://www.macupgrades.co.uk/store/images/466-img-main.jpg!
    It extends the unused motherboard SATA ports to the back panel. Cheaper, but requires you to partially disassemble your Mac Pro to install it, and the drives thus attached are NOT swappable while your Mac Pro is powered on - necessitating a power-cycling of your Mac to mount/unmount drives connected to this card.
    With the E2P you can mount/unmount drives without powering off your Mac. I'd go with the E2P!

  • Mac Pro Early 2008 crash after gear on boot

    Hi. I have a Mac Pro (Early 2008), with Mavericks installed. A couple of days ago, it crashed hard (in Portal, as it happens) and then wouldn't boot. When it was crashing it showed full green in various (dark? or random?) areas of the screen, and then random vertical lines of coloured noise. The cursor went jerky, and then stopped moving at all. Having decided this was a more serious problem than a simple steam error, I forced the machine to shut down with the case button, and then turned it back on again, but it wouldn't come up, and hasn't (with exceptions, see below) since.
    The behaviour is:
    Boot chime, Apple, Apple-with-spinning-gear, a sensible (it seems) amount of spinning gear, then the gear stops and I get some flashing on my screen (like, a complete red screen, or orange screen – colours vary – displayed for less than one refresh, so I see a brief flash of colour with tearing). Occasionally instead of flashing I get an unexpected reboot: once when this happened I also got the kernel's (multiple language) "Your computer restarted because of a problem" screen.
    Safe Mode has the same problem (I get a progress bar, when the progress bar completes everything stops and "screen flashing" happens).
    EFI boot volume selector works fine, but when I continue to boot, either from my main partition or the Recovery partition, I get the same problem.
    Verbose mode works until the point where the graphical user interface should come back, which gives me a white screen and nothing (except screen flashing). I do get a certain amount of "kSMCBadArgumentError" before that point, but see below.
    Single User Mode works as it should, fsck finds no errors, all my data appears to be on my hard drive as expected, but on typing "exit" to continue boot I end up in the same position as Verbose Mode. Trying kextload to load all my extensions gives the kSMCBadArgumentError lines, but no other problems (until I try to boot). I have already tried using SUM to remove all the launch agents/daemons/extensions from /Library/ (leaving only the ones in /System/Library/). This worked (I modified the disk as I intended) but didn't help me boot.
    I did get the recovery partition to boot once (seemingly randomly), Disk Utility found no errors. The full Apple Hardware Test doesn't seem to be an option from the recovery partition? (I've moved house a few times in the last 6 years, and I don't know where my physical AHT disk is any more. I do have a friend who would probably be able to burn one if Apple provides the disk image as a download.) I have had a full successful boot once too (maybe on the restart after using the recovery partition?) which let me use my administrator user perfectly (I used it for about 5 minutes?), but then after logging out and while trying to log in as my "standard" user I got full green noise as before, and the machine locked up again.
    I've rotated my RAM (I have 2x1GB sticks and 2x2GB, as well as my usual 6GB config I've tried each of the pairs in "two-stick" configuration). No difference, except on one boot I got error lights (full on) on one riser, I assume that was because I hadn't seated it properly during rotation, because I took it out and put it back in again and I've not had the lights before or since.
    I've also tried swapping in an older system drive, but that made no difference. (The old drive may have been a little flaky itself, but single-user mode booting reliably suggests, at least to me, that my normal drives aren't the problem?)
    Without wishing to privilege a hypothesis, could it be the graphics card? I have the Nvidia GeForce 8800 GT, I believe (it looks exactly like the pictures of that card online, anyway) – installed by Apple at build time. I tried taking it out and putting it back in again, in case it had become poorly seated, but it seemed firmly in place – for example, the PCIe retainer clip was fully engaged before I removed the card – and reseating it didn't make any difference. I don't have a second card to test with, unfortunately. I wouldn't mind getting a new card to keep the machine running, of course, but I'd like to make sure that it's going to solve my problem before buying it!
    Thanks for any help you can give!
    Edited to correct OS field, which didn't work. I really do mean Mavericks.

    RE: Mac Pro Replacement Graphics cards
    1) Apple brand cards,
    2) "sold in the Apple store" cards, and
    3) "Mac Edition" cards ...
    ... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
    1) Apple brand cards:

    • EVGA GTX 680 Mac Edition, about US$600
    The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
