Gray Screen after I log in to MacBook Pro

Hello,
I have got MacBookPro 2009 Model.
It was running fine till yesterday. I was watching a youtube video and I paused it and went away. After I came back the screen froze so I did the restart.
Initially, there was some issues with booting up. I used Use Single-User Mode to check disk, and disk is working fine.
But now after I log in I only see gray screen. No icon no logo nothing.
Help Please...

riteshkadu,
which version of OS X is on your MacBook Pro? Do you still have the two grey installation DVDs that originally came in the box with your MacBook Pro?

Gray screen shows up upon starting my macbook pro, it won't work

My Macbook pro starts up normally then appears a grey screen with a rotating white circle and no matter what I do, it won't work. How do I fix it without going into the store? I have the disks with me.

I would highly appreciate it.

Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Weird gray screen/freeze boot issue with 2008 Macbook Pro

Early 2008 MBP. Gray boot screen with apple logo and spinning gear freezes. Now for the odd part. In the background I can hear iChat log in, and I can see the associated account as available via Bonjour so I know that behidn the scenes, the laptop is indeed logging in and launching the desktop. I also managed to remote in and can see the desktop normally. The screen remains frozen.
I was able to initially get it working by resetting PRAM and NVRAM but that is no longer working either. Also tried an SMC reset.
Can't boot from CD or recovery partition (same result..gray Apple Logo boot screen freeze).
Booting it in target disc mode allows full access to the HD without issue. HD was checked (no issues) as well as permissions the one time I did get a desktop.
Any ideas?

Was able to pull this info from the kernel log.
Feb 8 21:02:38 Username kernel[0]: NVDA: rmStart failed
Feb 8 21:02:38 Username kernel[0]: NVDA,Display-B: Not usable
Any suggestions? It appears that the video is not initializing properly. Not sure at this point if it's a hardware failure or not. I tried reinstalling when I managed to get to recovery console, but that doesn't seem to have helped either. That only overlayed the files on the partition though. Perhaps I should just try a complete reformat?

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Gray screen after login - Cinnamon 2.2/Nvidia 334

I did a -Syu, saw the new Cinnamon. I then proceeded to snapshot my btrfs root vol, and went ahead with the upgrade. Rebooted, no desktop, just a gray screen with the pointer. I then booted off my install media, and mv'ed my snapshot back to replace my /
Unfortunately, that still somehow didn't fix it, which makes me think a conf is borked in my home dir (not in the snapshot). Nothing in the system journal.
Any ideas?

After 10.7.4 update macbook pro won't sleep

after 10.7.4 update, macbook pro won't sleep.

Test after each of the following steps that you haven’t already tried:
Step 1
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

I can't remember my password to log into my macbook pro. Help?

I can't remember my password to log into my macbook pro. Help?

First, make sure caps lock is not on.
You must back up all data before continuing, unless you've already done so. If you need to back up but can't log in, ask for instructions.
If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise*, boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead the instructions on this page:
If you forget the password and FileVault is on

TS1367 after a software update, my macbook pro was supposed to restart, since then, it doesn't restart & there is nothing i can do, any help please ?

Hello,
after a sofware update, my macbook pro was supposed to restart,
since then the start up process begins & after few seconds, the mac goes back to off without starting, what's wrong ?
thanks for any support,
Amine

Let me add a little bit of details,
after the software update, I was asked to restart my laptop,
while doing it, I got a message error :"some files couldn't be updated".
Since then, everytime I start my macbook pro, I have the grey apple & screen, with a kind of updating bar (grey as well) at the bottom,
when the bar reaches approximately 30 to 40%, it disappears & the laptop swiths off.
Ihave tried to start on a safe mode, it doesn't work either,
thanks
