TS3423 17" macbook pro won't start blue file with question mark is all that appears on the screen

My old macbook pro will not start up. Worked fine yesterday, today all I gat is the startup sound and a blank blue screen. After a while the screen shows a file folder icon with a question mark in it. Any ideas

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by:
Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
Boot drive's directory has been corrupted - Repair with Disk Utility.
Critical system files are damaged or deleted - Reinstall OS X.
The disk drive is physically non-functional - Replace the hard drive.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD:
Boot From 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.

If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

My macbook pro won't start up. I get the white screen and the grey apple icon   the spinning wheel......and it doesn't change !

My macbook pro won't start up. I get the white screen and the grey apple icon   the spinning wheel......and it doesn't change !

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

MacBook Pro won't start at all - clicking noise with black screen

Early 2011 MacBook Pro won't start: makes clicking noise after power button is held down, but no screen movement and after click, sounds like computer just stops working. Already did a SMC reset, and undid battery to try to run on charger power only. Same result every time. Also, my Apple Care expired 3 days ago. A few weeks ago had to repair a disk using Disk Utility because there was a discrepancy between how much storage was in the drive versus how much was actually being used.

You likely have the problem that many of us 15" and 17" 2011 models are having: a faulty soldering GPU and as discussed here -> https://discussions.apple.com/thread/4766577?tstart=0. It usually, but not always, beings with screen glitches and then gets to the point where the machine will simply not boot.
It's ashamed that you're not longer under AppleCare which would have, at least, got you a new logic board. A new logic board, however, doesn't usually fix the situation - only a BGA Reballing of the GPU seems to have long-lasting fixes.
Read through a few the articles (not all of them!) and make the decision yourself - and then make the decision about whom your going to contact.
Good luck,
Clinton

Here's a link to a Support page on the topic, which may be of help in finding resolution:
•A flashing question mark or globe appears when you start your Mac
There are a few known causes of this symptom, so you'd have to try some things to
see if you can narrow down the cause; this often accomplished by finding success.
Hopefully the info there helps.

17" Macbook Pro won't start at all. I shut it down last night at 80% and now there is only black screen, no light, no sound. What to do?

My 17" Macbook Pro won't start at all. I shut it down last night at 80% and today I get only a black screen with no sound, no light, nothing. The power cord light does show orange when plugged in. I don't know exactly which OS it is. It's model # A1286. I've tried all the tips about holding down different keys to no avail. Anyother ideas? (The serial # is w8******agu if that helps.) Many thanks.
<Edited By Host>

I had the exact same issue... Macbook Pro late 2008 with Core2Duo. Went to all the steps suggested in the knowledge base, tried to reset the SMC, but to no avail. Took it to the Macstore in Mexico, the wanted to replace logic board for $800.... Finally, I sent it to a logic board repair service, where they "fixed" the logic board for $200. It worked perfectly for 4 months, then happened again
Any ideas?? I would appreciate any help!!!!!

Attn: macbook pro won't start up past grey screen NO MATTER WHAT

my macbook pro won't start up past the grey screen, NO MATTER WHAT I DO. i've searched all the discussions on this, and NOTHING WORKS. nothing caused this either - i was just browing the internet and using ichat, and my computer shut down, and that is when this started.
I am EXTREMELY disappointed with this bullstein. My computer works great, etc., and I support mac and apple to the nth degree, but then some stupid crap like this happens and I can't use my computer at all. I have to use my sister's **** ibook g3 to even do this.
PLEASE HELP. do NOT post what you have already posted in the other discussions, and i've already been welcomed to the boards. I can't go to an apple store because i'm on vacation in new mexico for the summer, and there no stores anywhere near here. is there any real advice around here? I need to use my computer. That is why I spent close to $4,000 for it with upgrades and software.

where can i get an install disc for the macbook pro?
You really need to use the one that came with your MBP. If you don't have it, a retail Tiger OS X disc should work.
also, could an archive/install potentially free up some harddrive space on my computer?
No, it will actually use more space, so you will need at least 6G of free space. To clean your hard drive, use WhatSize.

Macbook Pro won't start-up (black screen)

Hello,
I'm having some problems with starting my Macbook Pro
specs of my macbook pro are here: http://support.apple.com/kb/SP13 (15,4 inch 2,2 ghz)
My macbook pro won't start up anymore, i press the start-up button, it makes the 'krie'-sound then the vans start spinning slowly and then he get's quiet. (screen stays black and the light at the mousepad is on).
I tried:
-Connect it to power and wait 15 min. then try again -> same result
- hardware test (installation disc 1 and then press d) -> screen stays black but the disc starts spinning
- pram-reset, -> same result
the only thing i didn't do is check if my ram-sticks are still in position (i never bought new ram, but maybe it started to get loose)
what to do?

Just google Nvidia 8600m, and problem, or oh god my screen is dead, and see what comes up.
Once again, if you have a Macbook Pro from mid-late 2007, chances are you have a bad chip. They will replace your logic board, with another bad chip, which may or may not go bad. It's an obvious issue, Nvidia admits they have a problem, and Apple is just going to quietly resolve individual problems.
If your computer turns on but the screen doesn't, it's about 99% likely it's the GPU. Go ahead and let Apple replace it. Oh, and if you have a MBP from that time period and don't have apple care. GET IT NOW. You will most likely have a Black Screen Of Death at some point, and Apple care is cheaper than the repair (which may or may not work). Some people have gone though three logic boards. Good luck.

1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

The folder with the question mark indicates that the machine is unable to find a bootable volume on startup. This is typically caused by one of three things:
1.) The internal HD has failed or is failing and needs to be replaced
2.) There is significant directory damage to the volume that requires repairing in order to boot
3.) Some other internal component failure between the HD and logic board
I'd ranked them in the order that is most common (from my personal experience). Boot to the OS X Recovery tool and attempt to repair the startup volume. If that fails or the drive is not detected it's usually a tell tale sign of a failed HD.

Macbook Pro won't start at all, no chime, no gray screen, nothing

My 2+ year old MacBook Pro won't start. Nothing happens when the start button is pushed, no chime, nothing. I've tried Control-Command-Start; nothing. I've tried with and without power connected; nothing. I've unplugged the power adapter from the wall, still nothing. Any ideas?

You can try a SMC reset, but it that doesn't power something it needs repair or replacement.

I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.

I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!

Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!
