MacBook won't start up just getting a grey screen and wheel spins

My MacBook will not go pass the boot up screen (grey screen with apple logo) the wheel just keeps spinning. What can I do to fix this ?

I assume you do not have Lion or later installed. What do you have - Snow Leopard? If so, then try this instead:
Reinstall OS X without erasing the drive
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.

I have a mac 10.4 and won't start up, just a blank screen with the restricted icon appears

Last night I forced shut down on the computer because the colro wheel wouldn't let me do anything.
In the morning i turned it on normally from the power button and it never started up.
Just a blank screen, forever...
I tried the safe mode and nothing happened.
Also tried holding the shift key after boot up and the apple appeared, then the RESTRICTED ICON.
I tried holding the option key and nothing either.
Tries command, option +P+R and I got the same restricted icon!!!
I can't remember when it appeared the march kernel erro in a black screen and then nothing...
I don't have the installation cd.
What can I do now?
Whatever I do I get the restricted icon.
I am at my witts end...
I know is an old mac, but can't afford a new one..and I have al of my work info and files there!
(most was backed up though!...phew...)
THANKS IN ADVANCE FOR YOUR HELP..

Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Windows 8.1 doesn't start after update. BLACK SCREEN AFTER LOGIN

Before all, sorry my english, I'm brazilian and don't found the solution on the brazilian version of HP website.
After I did the updates, the system ask to restart the notebook, so I did it. And now, when I do the login, after the password page, the Windows doesn't starts. Just a Black Screen appears.
I can't open the right side window to acces the configurations, and this laptop doesn't have a battery to take out and put in again.
I had already restore the system.
So, I use my laptop to work, and it has only 4 days of use.
I need help! Thanks!

Hi,
Run through the following procedure.
Boot the computer normally and log-in.
At the black screen, hold down the ctrl and alt keys and press delete.
Select Task Manager.
Click on File and select Run new task.
Type cmd.exe - also enter a tick in the box for 'Create this task with administrative privileges' - and click Ok.
Type in the following command ( including spaces ) and hit enter.
Dism /Online /Cleanup-Image /RestoreHealth
This will take a while to complete, but when it’s finished, restart the notebook.
If the screen is still black after you log-in, once again, hold down the ctrl and alt keys and press delete.
Select Task Manager.
Click on File and select Run new task.
Type cmd.exe - also enter a tick in the box for 'Create this task with administrative privileges' - and click Ok.
Type in the following command ( there's a space between sfc and the / ) and hit enter.
Sfc /scannow
When the scan has finished, check that the result is ‘No integrity violations’, then type exit and hit enter.
Restart the notebook again.
Any change?
Regards,
DP-K

While updating the firmware Update, i disrubted the download and now my macbook won't start up! Any suggestions on how to fix it? i only see a black screen

While updating the firmware Update, i disrubted the download and now my macbook won't start up! Any suggestions on how to fix it? i only see a black screen and when i press the power button i hear the noise that it would make if it was going to start up. But i only see black.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

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....

MacBook won't start up it shows the apple logo and just keeps the "wheel" spinning

MacBook won't start up it shows the apple logo and just keeps the "wheel" spinning

Usually means that critical system files are corrupted. Start by:
Boot into Safe Mode if possible. If it boots into safe mode, then restart the computer to see if it will boot normally. Otherwise, reinstall OS X. Unfortunately, you've not provided any information in your profile about what version of OS X you have installed.

Macbook won't start, just a flashing folder w/ "?" appears

macbook won't start, just a flashing folder w/ "?" appears
this happens after it hanged-up and I turned off the power

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

My MacBook Pro won't start it just goes beep beep beep when I press the power button

My MacBook Pro won't start it just goes beep beep beep when I press the power button

Hi Csound1,
I haven't added any RAM my daughter was using the computer then it hung so powered it down then the beeping started. Do you know if there is a combination of buttons I can press when powering up that will put me in some kind of safe mode so that I can find out what's up, I tried pressing D when the beeping started but it didn't make a difference.

I ran a settings up date on an iPad 2 and now it won't start back up. Just a black screen and an apple. Any ideas what to do?

I ran a settings up date on an iPad 2 and now it won't open back up. Just a black screen with an apple. Any ideas?

Have you tried a soft-reset to see if that gets it to boot up properly ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should reappear and it will hopefully boot up fully - you won't lose any content, it's the iPad equivalent of a reboot.

My camera is not working, just a black screen, won't take pics please help

WWhy won't my camera take pics..just a black screen ?

CClose the camera app and reset the iPad.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
