Mac Pro (2009) won't start, no chime, black screen

Hi,
I am having a problem with my 2009 Mac Pro. It fails to boot. There is no chime and the screen wont turn on;stays black. It wont boot off of the system dvd and I even tried installing an HD that has a good version of the the OS on it. I also tried booting from the DVD with no installed drives to rule out one of the internal drives doing someothing funky. Nothing happens at all, the HD or DVD will spin for a moment and then all is dead.
Any suggestions? Thanks in advance.

or this one:
Troubleshooting: My computer won't turn on
If no joy, remove anything and everything that may be dragging down the power, in hopes of getting a chime. This includes graphics card, any other PCI cards, all drives, and some say all but a minimal amount of memory. Look for the chime.
If you get the chime, you can build slowly up from there. Add back graphics card and keep going. Add back memory and keep going. Add back DVD reader and boot from Installer/Utilities DVD or run the Apple Hardware Test. And so on.

N97 camera won't start(just a black screen)

My N97 camera won't start just a black screen this issue since the update to the new firmware

ooooooooops so sorry about this, here it goes and start with the first code.
With all these operations I recommend you TAKE OUT MEMORY CARD and DO A BACK UP OF YOUR STUFF!!!
1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for ALL operations listed here is 12345
2. *#7370# - Reformat your phone (out of the box, tho keep in mind that most newer nokia phones at least n series, e series and s60 based phones have udp - user data preservation so not ALL data may be lost. still it is a good idea to always do a back up of your stuff.)
3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
hard reset - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM - use the following buttons to do a hard reset, GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800's that have firmware version 20... and up. ) For Nokia N97 (unofficial version but works) is SHIFT /SPACE BAR / BACKSPACE while holding the power button. Again do not let go until you see the handshake screen.
If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.
You know what I love about you the most, the fact that you are not me ! In love with technology and all that it can offer. Join me in discovery....

My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )
Here is a link giving further details about this chip solder problem.
http://macintoshhowto.com/hardware/how-do-i-get-my-broken-g4-ibook-fixed.html
Here is an example of a USB cady

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

My MacBook Air won't start up, only black screen no logo

I've had my MacBook Air since Christmas 2014. I have not spilt anything on it, I have not dropped it and the charger isn't broken.
Yesterday my computer wouldn't turn on, it was working the day before so I don't know why this was happening. When I turn on I mean:
Press the turn on key
I hear the chime for it to turn on
then all of a sudden
no logo only black screen and then nothing after it.
I really don't want to reset it because it has all my school work on it and very important pictures on it.
Is there anyway we can fix it? I've looked on this website many times and others and nothing has really helped.
If you have anything new please reply ASAP.
I need this fixed within 2 weeks.
Thank you.

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X 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.
Alternatively, see:
Reinstall OS X Without Erasing the Drive

Start up to black screen 2011 15" macbook pro

start up to black screen 2011 15" macbook pro does the start up chime and apple screen, then to a black screen, mouse arrow is visible and keyboard lit. help please

I had the same issue with my Macbook Pro too. You can follow this steps below:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.
Hope this helps!

HP Pavilion Entertainment won't start just shows blue screen

HP Pavilion Entertainment won't start just shows blue screen. Sometimes says missing operating system after changing boot order. I have seen error message 303. This happened after I couldn't stop coolncheap popups so I saved everything to another computer and did a complete restore. When I was in the process of getting it back to working order I allowed updates recommended and optional and then everything started.

Also pressing F11 won't take me to recovery

My ipod touch 2g 32GB is not starting, just a black screen.....

Hi friends and experts,
I need your help, since yesterday my Ipod 2G 32GB is not starting, only a black screen. I tried several times to turn it on but there is no reaction and when I connect it with pc, I mean with itunes also dead not detecting the device.

Hi,
Try connecting your iPod to your computer and letting it charge. It will take a while for iTunes to recognize it, if it is dead. Once iTunes recognizes your iPod, try resetting it again.
Hope this helps!

Imac wont start up after new RAM, no chime, black screen

Hi, I've recently purchased a used 2010 iMac i3 that had faulty RAM.
This was confirmed as the issue when I tested a friend's original RAM from the same age iMac and the machine worked perfectly.
I then ordered 2x 4gb Crucial memory (upgrade from the 2x 2gb already installed) but kept getting kernal errors and RAM integrity check errors so the modules were returned and replaced by crucial.
Prior to returning, I attempted to reinstall a fresh copy of mavericks, but the hard drive failed to completely format, and then the OS install also failed so the machine currently now has no operating system. However before returning the ram the machine would boot up and connect to the internet to attempt to download the OS again.
The replacements have now arrived, but after installing the machine won't even boot. First attempt to start there is a drive noise, and the fans run, but no chime and a black screen. If I force shutdown and try again the drive noise happens twice and the fans run, but the same outcome.
If I remove the RAM I still get the single bleep, and once of all of the times I've removed and reseated the RAM I've had a triple beep integrity check fail.
Any help would be massively appreciated. Lost now as to whether the issue is with crucials RAM or the iMac itself.
Thanks

Do you still have the old ram? Was orig sticks of ram bad? What happens if you put only one stick of the orig ram back in ?

Not fully starting up w/ black screen & no chime

My 15 month old 17" MacBook Pro decided to go to sleep this afternoon and never wake up. Had to hold down the power key to turn it off, but after that point, whenever the power key is pushed, the light immediately comes on in the front and it makes a slight sound (similar to waking from sleep).. no startup chime, and the screen remains black.
I have tried resetting PRAM, Power Reset, changed out ram to the factory stick, and even trying to target disk mode it to my wife's iMac in the hopes I could pull off the most recent data.. to no avail. (wouldn't even show up). I tried to boot from the 10.5 disc and it just got stuck in the machine and wouldnt see it (though I can hear it spinning up in there when I attempt a restart)
I have never seen anything quite like it in my years of dealing with Macs and it has me quite perplexed. I have trolled all the forum posts that include "not starting up" and have tried every trick mentioned. Suspect is the hard drive at this point, but the Logic Board keeps coming up in posts so I am not ruling that out. I have an insurance policy that may cover this but I am trying to revive it before resorting to that (or driving 2 hours to the nearest Apple Store)...
Anyone have any other suggestions? I would try a key on a kite in a lightening storm at this point if I thought it would help (though I suspect that power surges/outages we have had here the last few days are the culprit since it was not even acting any different until a few days ago.. even though I have it on a UPS) Help!

Are you sure the screen is totally black? My Core Duo MBP started up to what I thought was a black screen. when I turned on the overhead lights I could just barely see something on the screen. When I used a bright flashlight I could seee that my desktop was there. The problem was the backlight going out. This is repaired by replacing the inverter.

Start-up problems, black screen or open firmware

My iBook G4 1.33GHz Dual USB, with 1 gb RAM memory has been troublesome lately. It's installed with the latest version of OS 10.4.9
When starting up the ibook, it will sometimes only show a black screen after the boot chime. Repeated force restart sometimes makes it boot up the open firmware (white screen).
Then I see the error message:
"Illegal instructions at: %SRR0:ff85e778 %SRR1:00081000"
When I continue on with "mac-boot", I get the blue screen with a question marked box. So it can't find the startup disk.
This usually only happens when I'm done working for the day and close the lid on my ibook without manually clicking on the sleep mode when I put in in my drawer,. I've seen several times that the screen is still on when I close the lid, so it will continue to burn battery time.
I've managed to get the ibook to boot properly after removing the battery and letting it "cool-down" for 15-20 min. Also, zapping pram, vram sometimes works, but I don't know how much that actually helped. It worked once when I typed in the reset-nvram in the open firmware screen too.
I'd rather not have this happen at all! Any suggestions? Is this the much-talked about RAM memory failure?
Any suggestions would be very appreciated.

HI,
*"I get the blue screen with a question marked box."*
That can mean several things. One, the drive is failing. Two, your iBook can't find a System Folder to boot from. Try booting while holding down the Option key which will prompt the Startup Manager window.
MemTest
Boot from your install disk and check the hard disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window where you see Capacity and Available. Make sure there is always 15% free disk space. Not enough disk space can cause directory corruption.
If you cannot boot from your install disk, try booting in Safe Mode
A flashing question mark appears when you start your Mac

Won't boot into system (Black screen/ backlight on) - faulty logic board?

My iBook g4 12" 1.33 Ghz doesn't want to boot into the system.
1. Start computer (chime sound)
2. Apple logo on grey background appears
3. Spinning wheel below Logo appears
4. Screen flicker, big vertical zigzag appears, black screen (backlight is on)
5. Shift key work (led on/off)
6. Num Lock key works (led on/off)
7. no responses with any other keys on keyboard
What I tried so far
1. Reset PRAM & NVRAM & PMU
2. Put original installer disc in, press C start from DVD - same as above happens
3. Boot from external hard drive with operating system over Firewire - same as above happens
4. Mounted iBook drive as external drive with target mode - Other computer boots fine with iBook drive
5. Attached an external monitor, which doesn't get a signal
6. Run Hardware test over DVD - Diagnostics all fine (Screen fine all the time, running through all diagnostics)
7. Tried pressing on the graphic chip, as some forum entries suggest - didn't change anything
8. Start in Safe mode with [shift key] - no indication that in safe mode, same faults
9. Start in [single-mode] (see image http://www.somethingonline.org/dl/pb/singlemode.jpg)
Don't know what else to try
Any help appreciated

By booting off of various other drives (optical and external HD) and getting the same results, I think you are correct in assuming that something else is wrong in the hardware. You might make a call to one of the places that repairs books (like the ones in back of MacWorld) and see what they charge to diagnose and repair. But it may just be time to get a new machine. I'm in the same place myself right now; my G4 iBook seems to be on the way out.

Mac Pro - crashed and now won't start up, stripes on screen + kernel panic?

My computer apparently crashed while the screensaver was up (I was away for 10 or so mins, just Firefox and World of Warcraft in windowed mode running), as it was showing a black screen with a fuzzy whitish line along the top and was completely unresponsive. Unusual, but nothing to freak out about.. right?
So I did the on switch turn off/turn on routine and as soon as anything shows on the screen, I've got these black + white horizontal bars/stripes along the top 1/4 of my screen. The Apple Logo and the spinning progress bar have little fuzzy red spots on 'em. That's when it's time to freak out, as we're in "my computer done broke itself" territory. A few seconds of fuzzy progress bar and we get the wonderful "You need to restart your computer" message.
Fine.. restart.. same thing.
Reset the PRAM and SMC. Same thing.
Can't start up from external disks.. it just gives the same stripes + message.
I'm running a detailed hardware test (the hardware test loads but with the same stripes at the top and annoying blue/red vertical ones in the background to boot), and it's been running for about 80 minutes and is only 60% of the way through.
Anything else I can do, or do I have to drag the heavy thing to an Apple store and leave it there for a month? How in the world does a computer go from "working fine" to "completely broken" in 10 minutes?

More details:
The regular/non-extended Hardware Test returned no problems, despite taking hours for what was supposed to be a 3-5 minute test. I haven't dared run the extended.
I also tried removing third-party RAM and using the original configuration, then just the third-party and no Apple, etc.. It's not the RAM, as the problem is exactly the same.
I'm going to call up Apple support when I can, but just looking for other things I can check or possibly do until then, or just insight on what the problem could be.
Is it most likely the graphics card? Could it be an issue with the core hardware?

Windows 7 partition won't boot, hangs on black screen / blinking cursor

Hi all,
I just installed windows 7 home premium x64 on a new 100gb partition I made first with bootcamp assistant and then simply with disk utility the second time. I can't get windows to load however, it just sits forever at the black screen with blinking cursor at top left.
I have tried the Bootrec.exe /Fixmbr
bootrec.exe /Fix boot
Bootrec.exe /rebuildbcd
fix that is floating around to no avail. The rebuildbcd command yields 0 copies of windows installed but still ends successfully.
i have spent the majority of my day trying to get this to work and have no leads left anymore. Please help!

I HAVE SOLVED MY PROBLEM! Windows is running excellently on my Bootcamp partition.
Taking a few steps back: I used Bootcamp to remove the disk utility partition, then remade it also using boot camp assistant. Ran the windows install, and this time instead of hanging endlessly on black or going back to step 1 after restarting, the install went all the way. I had to restart once when the computer hung on "starting windows" but it got back on track right after this.
I think I must've fudged something with Disk utility before.
Thank you so much for your help!
