Frozen login screen even after restore and reinstall

When I am starting my MacBook Pro 15" (Mid 2010) I often have a frozen login screen (where I enter my account password) and the only thing I can do is press for seconds the power button. I have already tried to reinstall MacOS X Lion and even a restore from my time machine back up but the problem still appears. Is there anyway to resolve this problem? And is it possible to erase everything and reinstall Lion ?

Yes a clean install will erase everything in your hard drive.  Be aware you should have a clone backup (which I prefer) or a time machine backup so that the migration assistant can copy your user and all preferences.
if you mac already has lion installed you could
Restart your computer while holding the option key. After the startup chime you will see your available boot volumes. Choose Recovery HD. (You might be able to start up with command-r to boot directly into the Recovery HD emergency partition, but I have found that only the most recent Macs will respond to this key combination.) Once boot is complete, look under the menu bar's Tools for Disk Utility. Start up Disk Utility, choose your main hard drive partition, and reformat to your heart's content.
You won't be able to perform certain partitioning tasks when booted this way, but you can do nearly everything that you could do if you were booted from an external device or optical disc.
or another option is:
Make a bootable DVD or USB stick .  I will guide you through the steps:
If you don't have a copy of the install mac osx lion.app redownload again from the app store
Before doing this you should make a clone of your hard drive or have a time machine backup at hand, that is a very important step.
1. right click or control click on the lion install file and select show package contents.
2. Navigate to Contents>Shared Support
3. Inside there is an dmg image called InstallESD.dmg
4. Burn image to a blank DVD or usb stick with program of your choice (USB stick works faster while booting).
5. Restart holding option key
6. Select DVd or usb stick you just made.
I hope this helps.

  • MAC MINI BOOTS WITH VIDEO CORRUPTION (scrambled pixelated screen) even after restore and ram change, OK IN "SAFE MODE"

    Would there be a MACOS Start-up item causing this considering it's OK with a "shift" boot?

    Hi, does this Mini have a video card, or integrated graphics?
    Likely it's the quartz driver, that is disabled in Safe Mode.
    See this great post by themachead on how to list the extensions in Safe Mode with System Profiler then compare to the extension folder!

    CS5.5 and OSX 10.9.4: Most applications will not launch even after uninstalling and reinstalling the Creative Suite 5.5. After my 2011 MacBook Pro 17 died, I had to purchase a new MacBook Pro 15 to replace it.  I performed a Time Machine installation from that 2011 machine, and only Distiller and Acrobat would launch (none of the rest of the creation apps).  So I ran the CS5.5 installer, uninstalled, then reinstalled, producing the same result. When I try to launch, nothing happens.  What next?

  • I still get plug in failure even after uninstall and reinstalled adobe flash to my mac os x 10.7.5 (4 bit) with flash 16.0.0.235 how do I get this fixed??? HELP

    I still get plug in failure even after uninstall and reinstalled adobe flash to my mac os x 10.7.5 (4 bit) with flash 16.0.0.235 how do I get this fixed??? HELP

    That crash appears to be casued by the Facebook plug-in.
    Create a new account (systempreferences -> accounts or Users & Groups on 10.7 and 10.8), make a new Library in that account, import some shots  and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

  • Apple TV blank screen even after restore?

    Can't see home screen or anything on Apple TV. Did restore on iTunes.  It said successful but still no picture.

    Howdy PWQuick,
    If I understand correctly you are unable to see anything on your TV screen even after a restore of your Apple TV with iTunes. I would use the other troubleshooting steps to help find out what is at fault here:
    Apple TV (2nd and 3rd generation): Troubleshooting video issues
    Your TV picture is completely black or has other quality issues such as static or blurry video
    Confirm the settings and configuration of your television.
    Check to verify that your TV's video input matches the HDMI connection.
    Refer to the manufacturer's user guide for assistance with changing your TV input or picture mode.
    Verify that your television meets the Apple TV minimum resolution requirements.
    Verify that the Apple TV's power cable and the HDMI cables are securely connected.
    When connecting to power, observe the front LED on your Apple TV for activity. If no light is visible, try a different power outlet or power strip.
    Connect the Apple TV directly to your television, bypassing any home theater receivers, splitters, repeaters, or switches temporarily.
    Inspect all cables for any kinks, tears, or other evidence of damage.
    Verify that the HDMI cable being used with your Apple TV is a bidirectional cable. Although rare, single-direction HDMI cables do exist. If unsure, try flipping the connection between your Apple TV and television.
    If all else fails, try a different HDMI cable.
    Change the Apple TV resolution:
    Press and hold the Menu and Up button on your Apple Remote for six seconds.
    The Apple TV will automatically cycle to the next resolution at approximately 20 second intervals.
    Press Play on the Apple Remote to keep the current resolution or Select to manually cycle to the next resolution.
    Reboot your Apple TV by holding down the Menu and Down button on the Apple Remote for six seconds. Allow the Apple TV a few minutes to restart.
    Note: If the Apple TV video functions correctly after bypassing a receiver, switch, or repeater, please refer to the accessory manufacturer's user guide for additional support.
    Thank you for using Apple Support Communities.
    Take care,
    Sterling

  • A window asked me to close firefox.exe so it could do something (AVG I think). Now, I can't open Firefox at all even after uninstalling and reinstalling.

    When I took my laptop, which is running in XP, to get rid of a
    number of trojans, etc, the computer tech put AVG on it. Since
    then, I have been getting random notices from AVG. I got a
    notice and clicked it before thoroughly reading it, assuming it
    was another one of these. It said something about closing
    Firefox, and I thought it needed to close Firefox so it could
    scan something. Ever since, I click on the shortcut or the file
    itself to no avail. Nothing happens. I've even tried
    uninstalling and reinstalling. Have I unknowingly changed my
    administrative settings?

    Annette,
    #In the menu bar, at the top of the Firefox window, Go to Tools -> Add-ons -> Extensions.
    # Locate ''each ''of the following extensions by name and click the disable button
    #Restart Firefox as prompted and see if the undesired toolbar has been removed.
    #The extensions to disable are: '''Crawler Toolbar''', '''MP3 Rocket Toolbar''', '''MSN Toolbar''', '''Search Helper Extension'''
    If you don't need some / all of those toolbars, consider leaving them disabled.
    You can probably remove these toolbars permanently from Start -> Control Panel -> Add/Remove Programs.

  • Installed FF7 but keeps saying ver3 even after uninstalling and reinstalling FF7

    was having problems with firefox crashing alot--had auto updates on--checked ver and said was ver3.6 whoa, installed ver7 and ran after install. but after closing and opening again would go back to ver3.6 so uninstalled fire3fox completly even bookmarks and such. then downlaoded and reinstalled ver7, newest, ran fine till i close and reopen then is ver3.6 again. anyone else? do not understand this. no other problems--except originally was crashing on certain sites--especially break.com when i stumbled there, but others as well. why i tried to update.

    Your UserAgent string in Firefox is messed up by another program that you installed. <br />
    [http://en.wikipedia.org/wiki/User_Agent]
    type '''about:config''' in the URL bar and hit Enter <br />
    ''If you see the warning, you can confirm that you want to access that page.'' <br />
    Filter = '''general.useragent.''' <br />
    Right-click the preferences that are '''bold''', one line at a time, and select '''''Reset'''''. <br />
    Then restart Firefox

  • Iphone 5 going crazy even after restored and updated

    I have an iphone 5 siri kept coming on and my apps kept closing and it kept taking screen shots i restored it and updated it and it is still doing the exact same stuff. I do not want to pay for a new phone. please help.

    Since buying a 3rd party charger cord (not the brick) just the FireWire cord, my phone has been acting possessed or hacked. I have watched it open my personal notes on my phone, add notes, random words & things to my sentences, using proper capitalization, then copying & pasting large chunks of my personal notes , then goes back to home screen, shows some 2-finger-gestures, copying/pasting, launching my email, then pasting in fragments of my notes into an email, then quickly sending it somewhere before I can see all that is happening. The moves are so fast. This ghost or 3rd party hacker that came for free from my Chinese made FireWire cord has been super annoying. Today it changed all my settings, & closed out over 30 web pages I had saved in Safari. This thing does what it wants, messes with your settings, browses around your phone, copies & emails your stuff, then deletes the sent folder trail. I have video of it that I may try to upload tomorrow. It put my phone on airplane mode last night so I missed calls & communications this morning. As I watch it, it doesn't seem like a script of behaviors being executed, seems slower with more random decisions being made, and even efforts to cover it's tracks. Very very very very strange. More of us need to come fwd so that this problem gets dealt with.

  • How do I get rid of the blue "downloading the latest applications" bar which won't go away even after uninstalling and reinstalling Firefox?

    Can't get rid of the blue "downloading the latest applications" bar that seems to be just hanging and won't go away. I uninstalled and reinstalled Firefox, but the bar is still there after 2 days. I updated something (can't remember what!) on I.E., and it had the same blue bar, but it had a box I could x out of so it went away on I.E. I don't know why the blue bar is there on Firefox, as I did the update while on I.E.
    == This happened ==
    Every time Firefox opened
    == I updated an application while on Internet Explorer.
