Mac Pro (2007) wont turn on

I bought a Mac Pro last May, and today our mains fuse went, and it will no longer turn on. There is no smell of burning, and it is pretty dust free. I changed the fuse in the plug to no avail.
Is there anything I can do? I don't have applecare.
What support can I get? It's under 12months old, so under limited warranty. I am no where near an apple store though, so can't just walk in.

You should have been running your system on a UPS for one.
When you need to reset the system, there is an SMC RESET button under drive #4 or zap pram/nvram or unplug from the wall for 30 seconds.
A Mac Pro should be on its own circuit with only little other equipment (no space heaters, window A/C, refrig etc).

My new mac pro tower might have died but i cannot tell. help

Left on my mac pro tower 4-core with 3 gigs of ram on all night as I often do. I merely power down the apple 23" monitor because that's the only that heats up. Came down in the morning, turned on the monitor and all I see is a white screen. just all white. never seen that before in all my years as a mac user. I made sure all connections were secure and rebooted. THen.... whiteness. blinding nothingness. I'm taking a wild guess here that the mother board is okay but the Hard Drive is dead? After work, I'll try to boot up from the start up dvd however.... it doesn't appear to even go through even prelim start up. i don't get the screen of death or anything. just nothingness.
Anyone had this problem? I got the computer and monitor about 6 months ago and it's been flawless. Didn't do anything different last night. no downloads..nothing.
Help!

Hi-
Try resetting your PRAM/NVRAM:
Resetting PRAM and NVRAM
-Shut down the computer.
-Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
-Turn on the computer.
-Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
-Hold the keys down until the computer restarts and you hear the startup sound for the second time.
-Release the keys.
If that doesn't work, try booting to Open Firmware (commandoption+of) and reset the NVRAM:

If still unsuccessful, but, able to boot to open Firmware, try disk repair using fsck:

Monitor goes dark on 2008 Mac Pro Tower with ATI Radeon 5870 Card

I have a 2008 Quad Core Intel Mac Pro Tower running 10.6.8.
The original graphics card had trouble with HD movies of any kind and eventually my screen would sometimes not turn on (stayed black) when the computer was turned on.
So I replaced the graphics card for both reasons to a ATI Radeon 5870 PCIe with a GB rather than the 256 that came with the machine.
The problem was solved. I got a new monitor, one that is like the latest ones and all has been working great for a few years.
Then recently the monitor started going dark while the computer was on. (no screen saver or anything like that, I can be in the middle of work on a photo or video).
Trouble shooting I have tried.
A forum said drag the mouse to the hot corner for a while and then back. Well, I tried, assuming I was dragging the mouse to the corner. Didn't work.
I tried using the keyboard commands to shut down the computer. It didn't work.
I tried plugging the keyboard into other USB ports and tried to shut down the computer. No luck.
The only thing that works is shutting down the computer with the power button.
on start up the monitor is back on.
Sometimes it works for days like this, other times the monitor stays on only minutes.
The monitor is fine. Tested my old monitor on the computer to make sure it wasn't my new monitor.
So the questions are:
Can it be over heating?
is it worn out, toast, done and or dead and dieing?
Should I buy a replacement graphics card VS finally upgrading and getting a new computer (lots of $$$$ but then I do work in HD Video so....)
any help is appreciated
thanks

Replacing FBDIMMs would be today inexpensive and worth doing.
No one knows if heat is an issue without your using thermal sensor monitor. Probably want to up the default fan speeds while at it.
And because you don't have Lion+ then even more reason to setup a small maintenace volume on another drive with OS X basic system for repairs. In fact you should always have a bootable backup or two you can rely on.
Restarting may work, or it may be you have now new issue with corrupt fies or directory that a safe boot even is no guarantee of fixing.
When in doubt, try a clean new OS install on another drive.
And FBDIMMs: $25 for a 2x2GB set on Amazon.com
You want to get the most out of what you have, a small investment in RAM, maybe recycle those drives for 2-4TB units. And an SSD will have system responding better and perform better.
My guess, the 5870 wasn't needed and was overkill and a 5770 for almost half would have been more than adequate.

Mac Pro Tower - Which Fans Cool All of What?

So I have a 2008, 2.8 GHz 8-core Mac Pro tower. I'm one of the many people who have problems with the fans. In my case, I can get really high fan speeds, and the problem seems to be due to a faulty temperature sensor. (Using iStat, it will sometimes show unreasonably high temps on a couple cores [or the heat sinks, apparently] immediately after turning it on, whether or not it's been off for awhile. Sometimes, it will even show negative temperatures, in which case the fans will really go into overdrive. Yes, I've already tried resetting the SMC and cleaning it out - nothing.)
What I've ended up doing so far is download Macs Fan Control and setting it to base the fan speeds off CPU temps that don't give faulty readings. This works really well for lowering the fan speed (and thus noise), but I understand that different fans cool parts of the system besides just the CPU. The fan names give basic descriptions, but not a lot of detail beyond that. I've been trying to find a diagram showing which fans cool which parts of the system, but I mostly get results about fan noise, or minimalist diagrams that don't tell me all I want to know. I'd like to make sure my settings are fairly optimal before I do anything intensive.
Can anyone help me with this?

I think you are "barking up the wrong tree".
The fans in the Mac Pro are controlled by Software in the System Management Controller. They make a feedback loop based on measured temperatures. If you are getting racing fans, that is probably based on Bad Temperature inputs. Fixing the temperature inputs is where you should place your energy. The fans are slaves in this process.
One possible exception: Most of the fans do have an RPM output indicator, which tells whether they are spinning properly. If the diagnostic indicates a MOT error, that is likely to be a Fan Motor that is not showing high RPMs at High speed settings, and may be defective. The power supply fans were designed by a different team, and may not have the same controls.
What SMC Fan Control and similar software allows you to do is put a new Floor under the fan speeds. They will spin faster at idle, and it is possible they may move up to even higher speeds more slowly. What is does NOT allow you to do is any actual reduction in minimum fan speeds, regardless of whether it allows you to set lower numbers.
When the numbers get extremely large, the magnitude bits overflow into what is sometimes considered the sign bit. That has no meaning in this context -- all numbers should be treated as positive numbers. That probably indicates they took a shortcut and used general-purpose routines for signed numbers that were lying around instead of writing more correct versions for positive numbers from scratch.

Try zap PRAM and SMC Reset. If you have ATI 5770 which many have upgraded to you won't be able to use older DVD or systems than 10.6.5

FCP won't launch on new Mac Pro Tower

I just got a new Mac Pro Tower and installed Final Cut Studio, but Final Cut Pro won't launch. It just hangs on the opening splash screen and I can't even force quit out of it. Same thing happens if I try to open an FCP project. I have run all the updates, trashed prefs, etc.
Any ideas?

OK....so I think I found the problem even though it makes no sense to me. It seems that if I have my DVCam deck (which is connected via a 4-pin firewire to 9-pin firewire cable) powered on while I try to launch FCP, it causes FCP to hang on the splash screen. If I turn the deck off, and launch FCP, it launches perfectly.....and it continues to work after I power the deck on. Very bizarre behavior but I have tested it about 5 times now and it works fine when the deck is powered off and hangs when the deck is powered on. Anybody else have a simliar issie?

Logic 9 "disc too slow" 2 TB drive for recording audio on Mac pro tower, lots of system HD space 6 gigs ram?????

I purchased a Mac pro tower in 2008 it has a 320 GB system drive with lots of room left I have 2 500 GB drives and just purchased a new 2 TB 7200 RPM drive just to record from Logic onto it. I have 6 GB of Ram. I have been having this problem for years and I'm getting quite sick of it!.. I just set up a new 24 track project and I'm recording into logic via firewire with my Presonus firestudio and 2 digimax FS units at 44.1k and cant even record a few songs without it stopping in the middle of recording. This is sooo frustrating. Imagine when the band comes up with something cool and asks me to play it back and walk up to my $4,000 mac with my $500 worth of Logic to see it say Disc too slow!. I have seen this problem on many forums. Mac needs to fix this!. It makes me want to make a youtube vid of me burning my Mac with lighter fluid in the yard!. I purchased the "best of the best" at the time and Logic wont even work on a brand new Mac pro properly!?.. Cmon Apple help me out here???

Now that I've had time to stew over your comments. I do appreciate what you are saying however there should be another way to remedy this problem without having to purchase anything (ie in the software or an update, new version from apple). I ran a recording studio for Several years. I also did put a lot of thought and research into purchasing my Setup and had many compliments on the sound quality. What I'm saying is that Logic 9 should have no problem functioning on my computer. I think mac has made a poor product. I bet if I purchased the Pro Tools equivalent to Logic 9 that i could record 24 channels till the cows come home and get no errors. What I need to know is if there is something that I havent tried in my settings or software that can fix this. I think 6 gigs of Ram should be more than enough to work with. Here is what Apple has to say:
Minimum System Requirements
2GB of RAM (4GB recommended).
Display with 1280-by-768 resolution or higher.
OS X v10.6.8 or later.
Minimum 3.4GB of disk space. (19GB of optional content available via in-app download).
So why should I have to purchase any Ram when it's supposed to work on only 3.4 gigs?... That's why your answer frustrated me. I meant no personal insult. I just think there has to be a better answer out there. I do appreciate your input though .

I have a 30 inch monitor on my mac pro tower that just went black, what do I do to fix it?

I have a 30 inch monitor on my mac pro tower that just went black, how can I get it back on?

He's asking what are those things you are using, i.e., ...
What video card are you using?
What version of OSX are you using?
What model of mac pro are you using (e.g., 2010 Mac Pro is 5,1).
And also,
Try smc and pram reset.
And see if the monitor lites up if you boot in safe mode.
It is possible your monitor simply failed -- its power supply or something else.

I have a brand new Mac Pro Tower that continually kicks me off the internet and sometimes starts up not connecting to the internet?

My brand new Mac Pro Tower that I spent a small fortune on sometimes boots up and does not connect to the internet when every other computer in my office does and other times it just kicks me straight off. My question is, is there a problem with the wi fi on these machines?

Brand new nMP Mac Pro 6,1 Late 2013.... and it is defective - the older silver tower might be easier to find parts but at least it is not 65 lbs and is something that can be taken in - which I think you really need to do.
When you run etrecheck from www.etresoft.com it can show what is installed, drivers and might help point to something on software side.
Grant is the go-to person here I think among others for networking issues.
Airport Express and signal strength, channel it is trying to use, whether the Network control panel settings are "correct" or need to be changed (even the order, what it is trying to look for and use).
If you move it to another spot or put another computer over in that general vicinity...? behaves the same.
I recall reading where the MacBook Pro model in 2012? and switched to a new chipset and some very long (huge) threads in their forum - which means also there was no real solution given.
No, should not be. And other than network tests would be booting into Apple DiagnosticsTest mode - pulls down from Apple servers.

TS1362 I have a Mac Pro tower, am running osx and iTunes will not work.. It basically just stopped working after having run faultlessly for...years... I can see all the songs, playlists etc, but the progress bar will not progress..it's 'stuck'. Suggestion

I have a Mac Pro tower am running OSX and iTunes will not work. It has always worked flawlessly. I can see all my iTunes content- my playlists, my songs et cetera, But I cannot play anything. The progress bar is 'stuck'...any suggestions?

Thanks. I have been using iTunes since its inception and have never had a problem...I'm using the latest version. The progress bar is the bar that moves when you're playing a song..it just won't start when I double click on a song,..have tried quitting, rebooting etc but nothing works. Apple are useless-they have told me twice they've tried to call me 'momentarily', but I've been waiting by the phone, and they definitely have not tried to call...

I have a Mac Pro tower with two internal Hard Discs, each one 2TB. I purchased a 3TB Time Capsule. But it does not allow me to back up because it says there is not enough back up space available. Between the two HDs there are 3.3TBs. Can I daisy chain TC?

I have a Mac Pro tower (OSX version 10.6.3) with two internal Hard Drives, each one 2TB.
I purchased a 3TB Time Capsule. But cannot back up because it tells me there is not enough space.
I have more than 3Tbs to store to the new TC.
Can I daisy chain two TCs to store the 4TBs?
How can I back up only the internal HD that is already full, without backing up the other one?
How can I do back up using Time Machine to back up the 3.5Tbs?
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?

Can I daisy chain two TCs to store the 4TBs?
No, you cannot link to produce a single large partition.
But you can have two separate backup jobs.. and use each partition. That is hard on TM but you can easily get a different backup software for it.
How can I back up only the internal HD that is already full, without backing up the other one?
In TM you do a different setup and exclude the other drive.
But it is better to use an alternative software IMHO.
How can I do back up using Time Machine to back up the 3.5Tbs?
You would need to use a network drive of more than 4TB .. it would also take forever. This is just wrong way to do it. Although you can buy a NAS that will work with Time Machine and load it with disks 16TB is possible.. if you can get a second mortgage.. the fragile nature of TM on 3rd party devices.. would leave me in cold sweat if anything went wrong.
TM is excellent at keeping incremental backups of files that keep changing.. as such you should use TM to backup your OS disk and main user directory.. exclude all files and directories that never change. Back them up separately.
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?
Yes, that is a much better idea. You want to store photos safely and you want to store them in multiple places. If you have multiple TB of photos, dedicate a couple of disks to the backup. ie have at least two copies.. not in backup format.. in straight copy format if possible.. so you can keep one of the disks offsite.
I would be using your MacPro internal disk access, to place the disk onto sata bus and do the copy disk to disk direct. Or even buy esata card.. or sata to esata converter cable so you can use esata box. That will beat any other transfer speed except thunderbolt for which you would need third mortgage. (The MORT in mortgage is significant).
The great jurist Sir Edward Coke, who lived from 1552 to 1634, has explained why the term mortgage comes from the Old French words mort, "dead," and gage, "pledge." It seemed to him that it had to do with the doubtfulness of whether or not the mortgagor will pay the debt.

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!

Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Using Mac Pro tower as a Time Machine backup drive

Has anyone here ever done this? My roommate and I both just got new MBPs, and rather than buying the Time Capsule, I thought I might be able to use my Mac Pro tower as the destination drive for our backups wirelessly, but I can't find any information on the topic anywhere online. If anyone has some light they can shed on this, I'd be very much appreciative.
Thanks in advance for your assistance!
Timo
