Mac Pro Switching off repeatedly

I have a 4,1 Mac Pro, with 5 Gb Ram. Under heavy load it began turning off about 15 days ago; it seemed to be a temperature issue, because it occurred during the warmest hours of the day, (I have to say that I checked the temperatures with iStat and everything seems to be normal, the CPU temp never passed 77 ºC, and the computer went off at about 60º) I waited a little and then it began working normally. It happened two or three times in these two weeks, and then, last friday, I was working on some C4D renderings, it turned off and wouldn't turn on again.
On Monday, it worked perfectly fine during the whole day, but on Wednesday I ran the hardware test and got three different results.
The first time, I ran a short test, and showed no problems at all.
For a second try, I ran the extended test, and the computer turned off; I opened the side cover, waited a few minutes, turned it on again and about 15 minutes later i got a hardware error message:
4MEM/64/40000006:0x7a0cfl98
I thought it had something to do with the memory modules, so I took off the 2 Gb DIMM that did not come with the machine originally.
I ran the test again and it showed no problems at all. I did a test with C4D and with After Effects and the machine worked fine.
This morning, just a couple of minutes after I turned it on, I was watching a video somebody sent me by e mail, and the computer went off; I ran the hardware test and it turned off again; I opened the side cover, set again the 2 Gb memory module in the place it was before, left the cover open, and it passed the extended test with no problems, and i have been using it for almost an hour and a half with no issues.
Has somebody suffered from this before?

Just tha thought, but when was the last time you blew the dust out of your machine?

Can a Mac Pro boot off a MacBook Pro in Target Disk Mode?

Summary: "Are you able to boot a Mac Pro off of a Mac Book Pro in Target Disk Mode?" OR "Will a Mac Pro boot off an OS X install that was made on a MBP?"
Details:
I'm finishing a music project that was created on a PPC G5 Quad computer and going to a studio in Santa Monica to complete the final mixdown. My 3rd party software plug-in configuration is unique, and the studio doesn't have all of the software instruments that I do on their 8 core mac pro. My G5 software installation is mirrored to my MacBook Pro, but the MBP doesn't have enough CPU power to play the project back.
Is it feasible to have the studio's 8 core Mac Pro boot from my MacBook Pros hard drive? Essentially, we'd be using my OS and software on their powerful CPU / hardware. I figure, since they are both Intel builds of OSX, this should be do-able.
I don't have access to the Mac Pro until I show up to start working.
Thanks for any input / suggestions!

The MacBook Pro boots fine in 10.5.8, and loads the Logic project without any faults. The only issue is that a CPU shortage occurs when you attempt to play the sequence.
Like you suggested, I performed separate UB installations of all the needed software on the MBP solely so I could move Logic projects from one computer to the next without a hitch. (Actually, DropBox does this for me). Migration assistant was not employed in this process due to the PPC / Intel issues you noted.
I didn't need to mention the G5 as it appears to have caused some confusion based on Kappy's reply, but I did want to explain my work flow thoroughly.
It sounds like booting the MacPro from my MBP is feasible. I'll mark this topic 'solved' and head over to the studio tonight. I'll post here any anomalies from the session (if any).
THANKS~!

Macbook pro switched off won't turn back on

My mid 2011 macbook pro switched off while I was charging my iphone 5 with it (was using belkin cable since NY apple cable started ripping open at the ends and now it won't work).
This happened 2 days ago. I browsed through some of the community members having the same problem but none of it works for me. If I recall the macbook has 60% chsrge . I tried connecting my charger to the laptop it only lights up with a light green color that's hardly noticeable. Moreover none of the keys work it seems. Please help

You will have to take the computer to the Apple store to have it checked out.

Does anyone know when the Mac Pro switched from ATA to SATA DVD Drives

Does anyone know when the Mac Pro switched from ATA to SATA DVD Drives ?
I tried to find this answer online but failed.

Appears the Mac Pro (Early 2008) is the last model to suggest Ultra ATA/100 optical.
And with an optional card, use Serial Attached SCSI via Mac Pro Raid.
This kind of information gets sketchy in that the hard drive bus and other parts are SATA
and only this (and earlier) model Mac Pro has optical drive interface w/ Ultra ATA/100. The
logic board on the early 2008 appears to have two Serial ATA ports, 3.0GBPS; so to check
these, you may need to look into specification in iFixit.com repair guides, any takeapart
guides, and note specifications in everymac.com and those from mactracker.ca.
The MacPro after Early 2008 model build series (Early 2009) appears to sport an optical
drive with 18x speed, compared to Early 2008 & before, whose drives indicate 16x spec.
Other changes may be indicated by certain parts and differences; processors, graphic
support, and those kinds of things. 2008 shows dual-core, afterward, quad-core.
So on what little I found, that would appear to be the divide or when optical drive spec
on the logic board changed from Ultra ATA/100 to SATA versions. But double check.
Good luck & happy computing!

My Mac Pro shuts off after entering my log in information

My mac pro shuts off when my log in information is entered after about thirty seconds or so.

Hello again,
it seems I have solved the problem myself. In system preferences, Security and Privacy, General, I deselected Ask for a password after … minutes …. Now the computer goes to standby normally, and of course does not ask for a password any more after waking. I still do not understand why choosing this option should make putting into standby impossible.
I hope this finding can be of service to other users.
Goodbye.

Mac Pro switches itself off immediately after power button is pressed on

Hi there,
I would like to share with you an ongoing problem of my Mac Pro (about on and off 11 month I think). Since its HD changed at the beginning of this year I've been having the problem of "switching itself off immediately after the power button is pressed on." I took it to Milton Keynes Apple Shop and apparently they couldn't replicate the problem I received it after they reset it's PRAM. Meanwhile I read the related posts and discussions about the problem and my assumption was as suggested in the scenarios of similar cause – Power Supply unit. I had a technical chat with ex-Solutions staff from Brighton, he also said it might have been caused by it.
I really don't know what to do because, sometimes attempting 10 or over times of pressing the button I hear the chime and literally 10 or 20 seconds later it switches itself off. And it happened this Sunday morning again, 8 times I've encountered the failure. And the most confusing thing is sometimes I leave it about an hour or two and then it just works and runs fine as it has never have happened.
By the way I left my computer on for a very long time I suspect maybe more than a month it was on sleep most of time when i am not using it. But yesterday I made the mistake of logging off and shutting it down. Now I can't turn my computer on. Highly frustrating and amazingly bizarre technical challenge.
Mind you I am fairly capable of carrying DIY operations on it. Previously I baked my graphics card as suggested in the forum – it works fine at the moment I am waiting until it completely brakes. But this power problem really really puzzles me.
Any opinions, how to solve this cause is highly appreciated.
Many thanks!
Specs:
Mac Pro 8 core
Xeon 5400 2nd Generation Early 2008

The SMC especially on the very first 2-3 months of Early 2008.
Use to suffer from a "restart on wake from sleep" issue.
Some one told me that is not what "inrush current issue" is but that is what I (and couple others) called it.
Best to always have a workstation on 1500VA UPS.
Not share the outlet or cirucit even with anything major.
Yes it could I guess, poor phrase, but put more stress on PSU over time as a result also.
Methods to reset SMC have varied and changed over time. Thanks to web not all the revisions and older versions are kept online though to compare to.
Stories of people going on vacation etc for two weeks to come back to a "dead" Mac Pro started showing up in 2007.
If it had an actual SMC button, use that to reset.
If not, leaving it totally disconnected, and all external cables and such over-night, not for the mere 5-10 minutes.
Unplug but then press and hold power button for 8-10 seconds. And only once. And not to be done repeatedly. That was SMC Reset #3.
I know the 2007 8-core 3GHz had a different PSU than the smaller models.
2008 high end was 8-core 3.2GHz 5400 (stock was 2.8GHz 4 or 8-core)
FBDIMMs draw between 10W up to 15W each, so possible to have 8 DIMMs drawing 120W when maxed out. And heat. I always recommend Mac Pro use fan control to boost the fans a small 400 rpm to expel heat better and keep FBDIMM temps down. Heat, and temperature fluxuations stress and weaken components.
Other than AHT and the tools that a Apple Certified center should have, not much other than to swap out parts, monitor - iStatPro or Hardware Monitor -
And because of all this, I would setup a test system so you have a freshly formatted and installed OS and take it from there, with a better chance.
ATI 2600XT still? or upgraded?

Mac Book Pro switches off when you open Safari!

Hi people.
I am new Mac Book Pro user, have had it for a few months now and all is good, however I have an issue and that is that everytime I open safari and open a new tab the machine switches off! To turn it back on I need to wait for 30 seconds or so and then power it on. An error report is shown upon login and it happens again when safari opens.
Any ideas??

Take it to an Apple store or AASP.

Retina display on Mac Pro goes off randomly while working

My client has the latest Mac Pro (cylinder) with two screens, one of which is the latest Apple Retina display.
In my client's own words, here's the problem:
"My monitors have been really buggy. The retina display just cuts out - then randomly comes back on.
I have verified that all cords and plugs are secure and that the power source is on... it's been doing this since the beginning but is worse now.
Sometimes one stays on and the other goes off -- sometimes it switches. When I reboot the same thing happens.
I ran disk utility permissions and repair just in case and all seems to be in order."
Mac Pro (64G RAM)
I searched online but haven't found any info on this problem
Any ideas?

Howdy generatech,
To help resolve or troubleshoot the issue with these monitors intermitently turning off on their own, I would use this part of the following article:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
Reset the system
You can reset the Mac's parameter RAM and SMC.
Thank you for using Apple Support Communities.
All the very best,
Sterling

My macbook pro switched off and wont turn back on. i tried to charge it but it still wont work. how can i get it to turn back on??

My macbook pro randomly switched off and wont turn back on. I have tried to charge it but it wont work. How can I get it to turn back on??

It's more than likely broken, a part has failed. You need to take it to a Apple store Genius Bar to be checked out and fixed. Or just buy a new Mac as to fix the one you have might be cost prohibitive. Especially if your warranty has expired.

Mac Pro Clicks Off When Waking from Sleep

This is a recurring problem, that is all the more annoying for its lack of consistency. Occasionally when my Mac is sleeping it'll just "click" (it actually makes a clicking sound) and shut off immediately when I try to wake it. Pressing the power button does nothing.
After a lot of trial and error I've found that the best solution is to unplug the power cord and wait for maybe 15+ seconds. Then I plug it back in, press the power button and she starts up like nothing happened--as if we don't both know what happened.
I'm on a good streak now, and it hasn't happened for a while, but given my experiences with it, I can't really relax.
Any ideas? Thanks for your time.
Mac Pro Mac OS X (10.4.8)

I bet it's draw!
Yep, power draw. How about this for a knee slapper:
I had my MacPro plugged in to the same socket as a moderatly
stuffed PeeCee and every time I woke up the MacPro the PeeCee
would click off. The PeeCee PSU wasn't getting enough juice
and just turned off.
Now I have a poor electrical system in the current house that
I'm in. I think the Main breaker is 15 amps and the two that
split off are 10 each. So I can't toast toast and nuke some
cold coffee at the same time that the 3 PCs and the 22" CRT
are on in a lit room without the main breaker tripping. But
without the toaster and nukrowave running the MacPro when
waking up harshly dims all the lights in the house for about
0.5 seconds.
If your Mac is asking for more than it's getting there might
be some smart circutry in the PSU (like there is in most nice
PeeCee PSUs) that turn it off before it causes any trouble.
Make sure it's that only thing plugged into the socket that
you're using for it and see if that doesn't solve it.

Mac pro turned off by itself

i do most of my work on a mac pro (1,1)
and this evening at precisely 8:04pm my mac pro clicked and then turned off
the computer did not shut down, it just turned off
i should note that the click i heard was the same as the one that i hear when i first press the power button to turn it on
attached is console starting from 15secs before 8:04pm

my mac is on an APC ups and the power was stable at 8:04pm
programs running
mail
firefox
remote desktop
ichat (aim and bonjour)
internet sharing (to ethernet 2)
any thoughts on what could cause a power off?

Same here. MacPro 3.1.
ALSO on an APC (Back UPS RS-1500). Woke up yesterday to the sound of it (UPS) beeping, red light on, computer off. Happened today, same way. Checked energy saver settings.
Wasn't using it, so did not hear click.
MacPro starts ok, shuts down ok, sleeps ok.
I had it plugged into a wall socket for two weeks while I configured it. No problems. Only after plugging into to the UPS. This UPS has served well backing up a Dual G5 tower previously.
Battery shows 100%. No heavy periphs (like printers) online.
Had a multimeter in the UPS the first time around and got 122 volts in the line.
Could it be the UPS?

Mac Pro powering off and on

Hi All,
I have updated to OS X 10.7.5 on my Old Mac Pro (late 2008 or thereabouts) which was the latest OS X that was allowed. Since then it worked for a short while perfectly, then started to power on and off continually and I only occaisonally get it to stay on for 3 mins before it goes in to the power off/on cycle.
During these cycles it usally reaches the power up sound and then powers down ect
Please help!
Cheers
Paul

Ddi you happen to do a copy run start with module powered off? If so, I would think its expected behavior.

Mac Pro power off suddenly when remove power cord

hi, i've just got my new apple mac pro from the store fresh for 2 months, and my battery cycles have been only 13.
just now when i accidently uplug my powercord, it shut downs instantly, i'm so worried about this, i'm having a final exam in 2 weeks, and if it keeps happened like this i'm gonna be so unhappy.
is this a serious problem, anyone getting this ?
can i change it to new one at the store ?
I'm in Melbourne, Australia

That certainly isn't what should happen — the machine should instantaneously and seamlessly switch over to battery power when the MagSafe plug is disconnected, unless the battery is drained or dead. What was the state of your battery when this happened?
Please test again, with your battery fully or partially charged, the machine running, and no documents open. Disconnect the MagSafe connector properly by holding the plug and tipping it downward until the electrical contact is broken. Does the machine shut down or keep running? Post back with results.

Buzzing Sound While Mac Pro is off

I just noticed a very low bizzing sound coming from my mac pro. It occurs when the machine is actually off. Is this something to be concerned about? Do others have this very low sound coming from the computer while its off?

PSU first likely suspect I guess.
Also insure that if you have a UPS, that it is above 1000VA, also related to problems.
Mine causes a hum when in use, trouble is, that even after shutdown, my ears still ring (sounds like 100s of chirping crickets or just plain "tingling ears" that won't go away for hours once it starts.
Hard drives have often been able to set the whole metal case to some kind of hum or discordent clash of vibrations.
