Mac pro resets

good morning,
  I am currently having a technical problem with my Mac Pro (Early 2008) machine.  WHen the machine is powered on, It works fine but if the machine is bumped in any way, it completes a hard reset and I lose whatever information I was working on.  Has anyone ever heard of this problem or have a possible solution?  All cables are connected correctly and fully.  Thank you.

Please bear with me, as this answer may sound like nonsense at first reading.
The Mac Pro is unique in that its AC power cord has a large block or rubbery material around it. In my opinion, this encourages the user to not insert it as far as it ought to be inserted. Before you go nuts looking at other issues, be sure to power off your Mac Pro tower, and remove the power cord. Then jam it into the Mac as hard as you can. (Another alternative is to substitute a "standard" IEC power cord that does not have the large block around the computer end.)

  • Faulty Mac Pro "Red LED" on Processor Tray (not RAM LED)

    Hello.
    I have a faulty Mac Po and wondering if someone can advise.
    There's a red LED constantly switched on on the processor tray (see photos). It is not one of the RAM diagnostic LEDS.
    The Mac Pro does not load up. It does initialise the RAM and boot up the Hard Disks.
    At the same time the Graphics card fan spins very fast, and no input is detected on the display. I have removed it (in the photos) just in case it overheats.
    I have plugged in the graphics card and processor tray on an identical Mac Pro and they both work fine. I have also swapped out the small button-battery fo a new one.
    I have also unplugged all cables, reseated the RAM and removed any non-Apple RAM, leaving the shipped RAM in place.
    If anyone has any ideas what this might be I'd be grateful for a response.
    With thanks in advance

    Troubleshooting: My computer won't turn onhttps://support.apple.com/kb/TS1367
    Symptoms
    If your Macintosh computer won't turn on, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from showing video, this article discusses what to do if the computer won't turn on, meaning that when you press the power button:
    You don't hear a startup chime.
    You don't hear any fan or drive noise.
    The power button or power indicator doesn't light up at all.
    If your computer doesn't display any video, it may display one or more of these similar symptoms when you press the power button:
    You may hear a startup chime.
    You may hear fan or drive noise.
    You may see the power button or power indicator light up.
    If any of these conditions occurs, see Troubleshooting: My computer has no video instead. 
    Resolution
    If your computer won't turn on, try each of these steps:
    Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
    Make sure that the power adapter is properly connected to the power port on the side or back of the computer.
    Disconnect all accessories that are plugged into the computer, such as a printer, hub, or other mobile device.
    Reset the computer's PMU, SMC, or PRAM. Refer to the instructions for your model:Mac Pro

  • Location of the SMC Reset button in a Mac Pro

    I'm having trouble finding the SMC reset button.
    +The hatter+ said, "use the SMC RESET button inside, under drive #4. "
    This page http://docs.info.apple.com/article.html?artnum=304123 said;
    "Another way to reset the SMC on a Mac Pro computer is:
    From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
    Open and remove the metallic outer door.
    Press the SMC_RST switch that is located slightly below and to the right of the row of diagnostic LEDs. Use a non-metallic, non-conductive object, such as a wooden pencil.
    Replace the metallic outer door.
    Press the power button to start up your computer."
    I can't see any row of LED's - can't even see one inside there...
    Can anyone help me with the location of this button?
    Thanks

    Full glossy photos:
    http://mac.powerbras.nl/
    It is as small or smaller than the eraser on a pencil.
    It is easier to see with a flashlight and with the case over on its side, and pull out drive #4.
    I thought Apple had a page with a circle around it in the tiny pdf or manual that came with the unit. They should have it in the tech note.
    and if you have a PCI card in the top slot, someone said they had to remove it to get access.

  • Mac pro keeps crashing/weird colours/unable to reset/wont boot

    Hello. First some info. I have had my mac pro for 18 months. I am running OP system X 10.5.8. I have four 256mb ramss instaled(from purchase) and 250G hardrive.
    Now for 17 months, everything has run fine. Until one day after switching accounts, I noticed weird red lines accross the screen and I could not click on anything. I had to use the power button to reboot and then everything went fine until the next morning, after logging in, I got the red/pink lines accross the screen again and I was unable to click on anything.
    This problem went on for about a week but then things got worst. I was having to use the power button upto 4 times because when i tried to boot, it was stuck on a blue screen. This then became 6 times after a short while more.
    Before long, i was at the stage where i would click on my account to log in and the screen would just freaze. After several reboots, i was able to get onto the account but the computer then began crashing(with the spinning colour wheel in the middle of the screen) and i could click on nothing.
    I was thinking that my computer needed warming up or something but today, it has gone one step too far. Ive spent about an hour trying to get it on but everytime i click itunes/safari etc, i just get a frozen screen, often with weird colours. My computer is making horrible noises(like its downloading a song, if you get me) that do not go away.
    Now, ive done a hardware test and an extended hardware test but nothing came up. I attempted to re-install the operating system but that ended up crashing just like my computer does.
    For some reason however, i have booted in safe mode and there is not a single problem with anything. I can click on itunes etc etc and nothing crashes.
    I have apple care, what do you think i should do now? Could it still be a hardware problem? How do i find out if it is a software error?
    Any help would be fantastic

    milesmartin, did you ever resolve this issue?
    I find myself in almost the same situation. I have a Mac Pro using OS 10.6.1 with 9gb RAM and three hard drives. This happened suddenly at a cold startup for me. The strange red/pink lines, mouse not responding, etc. I could do a hard restart (power off) and the problem seemed to go away. I have tried many tests with TechTool Pro and the Apple hardware disk. All test show no problems with hardware. I have installed clean systems on a new hard drive several times including going back to OS 10.5. Each cold restart brings the same freeze, strange graphic displays. I reset the SMU, purged the PRAM, replace the battery, pulled/replaced all RAM modules, tried starting from the OS install disk. So far, nothing helps.
    At the start of this problem, I could do a boot in safe mode. Now, nothing works and it may take 4 or 5 restarts to get the system up and running. This is most unacceptable and probably stresses the components in ways that will eventually cause a failure.
    I am out of ideas today and it is no longer fun. Any help?

  • Can't reset alert sound on Mac Pro

    Last night I set up my new Mac Pro. I reset the alert sound in system preferences, after setting the audio input and output to go through the Kona LHe card installed in the computer. But when I checked the alert sound in the menu bar, it was not the same sound I had set. I tried resetting the sound several times with no luck. Does a Kona card interfere with setting an alert sound of my own choosing? I tried having the alert sound go through the card as well as setting it to go through the internal speaker. Neither setting made any difference. It's a small annoyance but I would really like to hear the alert sound I desire.
    Mac Pro   Mac OS X (10.4.9)   Two 3 GHz Dual-Core Intel Xeon, 2 gb RAM, Kona LHe card, 2 SATA 500 gb hard drives, 2 super drives

    Have you tried contacting the manufacturer of your Kona card?

  • Forgot user password, how to reset mac pro to factory settings

    hi guys,
    Recently I bought a used mac OS X 10.5, am very new to mac world. i am unable to load any softwares like wireless adapters since I am unable to get the password for the previous user. Also, I would like to reset the computer to factory settings, can I do that? Would you folks help me out!!
    thanks

    The Mac Pro has 4 internal drive sleds, no cables, that just pull out and slide back in.
    Pull out the original drive and see what else is there.
    Buy yourself or use one of your own drives.
    HOLD 'C' to boot from a DVD.
    Holding OPTION or Alt will show a boot menu of valid boot volumes (can include Windows even). You could boot from Windows CD/DVD and nuke the whole thing.
    Before installing, go to UTILITY menu and DISK UTILITY and ERASE the drive (not the subset volume).
    Assume you know your way around Mac and OS, yes?
    You don't know what was or wasn't, and if you don't own license for software etc that is on the computer, another reason to wipe it clean.
    Start from scratch.
    Call AppleCare Customer Support and they can send out discs for fee, insure it is 'legit' (need to give them the serial number from case).

  • Mac Pro 5,1 Fans full throttle, SMC reset does not help

    Hello Community,
    i have the following issue:
    - Mac Pro 5,1
    - Latest Firmware; no SMC update available
    - Fans (of case, not graphics card) running full throttle as soon as OS X is active (installed or in a installation phase).
    - During boot up, fans run at usual speed/silent.
    - SMC reset (according to: Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support) does not help the issue, nor did resetting PRAM.
    - Removing mainboard battery did not fix it.
    - Resetting the battery using the onboard switch did not fix it.
    - Detaching components and reattaching them (RAM etc.) did not fix it.
    - Detaching device from Power for a prolongued period did not help.
    - Apple Hardware Test AHT (off the original installer disk shipped with the device) tells everything is healthy.
    - Having clean installed OS X (both:latest releas and also orignal version from original grey installer disks) did not help.
    Then: installed MacsFanControl which allows for checking each of the sensors and each of the fans. using them one by one as a control for the fanspeed, which always succeeds: every sensor delivers meaurements, every fan reacts to adjustments of rotational speed.
    BUT: As soon as you choose to let the SMC do the job of controlling the fans, fans switch back to full speed again.
    All this after having installed VMWare ESX 5.5 on the machine and then having reverted to OS X 10.10.1/2.
    Looks highly like SMC won't get properly reset or may some setting is written where SMC reset does not operate?
    Any hint would highly be appreciated since i'm not sure whether i should trust this machine which is meant to act as a server.

    Hello Community,
    the above phenomenon turned out to be rooted in s.th. completely different & unrelated.
    Obviously there is a system's preference for the 1st PCI-E slot for the RAID controller to be connected to.
    You actually may well plug the controller into slot 2 and 3 as well, and the system will then still boot, even after having moved the controller to a different PCI-E slot (after having installed the OS!), but always the SMC will react like described above. Still not sure what the aforementioned symptoms actually indicated (jsut "irritated" SMC or SMC flat out inoperable) - time's too scarce to investiate this any deeper, sorry...

  • Resetting the SMC on a mac pro

    Hi,
    I need to reset the SMC on my mac pro, as I had an incident where the fans kicked in like a fighter jet after I shutdown, and didn't stop until I pulled the plug after about Ten minutes of white noise.
    The trouble is, the instruction for doing this are a little unclear, as I'm instructed to unplug everything, including the display cable, before reconnecting only the keyboard and mouse, after 15 seconds, before restarting. There is no mention, however, of reconnecting the display cables, which leave a few possible interpretations: 1/ Obviously I'm supposed to reconnect the display cables, or I wouldn't be able to see anything after restarting. 2/ I'm supposed to reconnect the monitor after start up (I think this is supposed to be a bad idea)? 3/ I'm supposed to restart without a monitor, and then do a forced shut down by holding the power button for 10 seconds, after I think it's probably restarted okay (hard to tell without a monitor). After shutting down, I then reconnect the monitor. Clearly, option 1/ is the only sensible interpretation, but as I'm guessing there's no way of knowing if the SMC reset worked or not, after doing it, except a non-repeat/repeat of the problem, I'd like to be absolutely sure. I hope someone can help me.
    Many thanks

    Yes, you can reconnect the monitor.

    It sounds like it is time to restore from the backups you made just before making the disk changes.
    You can re-partition and restore your backups.  If you didn't make backups first (you were warned that it might damage things and to make sure you had a good backup) then you will need to repartition everything and reinstall from scratch...

    Hit return key.

    If you have AppleCare & same is still active, suggest that you call Apple Customer Relations - 1-800-275-2273.  Ask politely & firmly that you want to be transferred to Customer Relations.  Tell them exactly what you stated in your post.
    Be sure to tell them that you have an iMac.  Why?  Because, under AppleCare, iMacs qualify for HOME tech repair/support when warranted.  No need to lug an iMac to a repair facility.
