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!

  • HELP!! Black screen on my MacBook Pro after leaving open and on for over 8 hours.

    Hi everyone,
    This is the first time I'm using the discussion board as I haven't had any problems with my MacBook Pro since I bought it in November 2010. However, yesterday, I left my laptop on and open for over 8 hours without realising. When I came back to my laptop it had a black screen that just wouldn't go away. I pressed all the buttons on my keypad to wake it up but this didn't work. The caps lock key lights up when pressed and the volume button makes the clicky noise when turned up and down but the screen is still black. I have tried turning the laptop on/off using the power button several times. When it starts up it makes the usual sounds and I can hear that it is on but the screen is still black.
    I do not use my laptop for anything complicated. I really only use it to browse the web. I hope someone can help me. I have tried to make an appointment with the Genius Bar but there are no available appointments at my local one. I'm not a mac expert and don't understand technical words so please speak in layman terms otherwise I won't understand. Any help would be greatly appreciated. Many thanks

    If you've a 15" version, maybe...
    Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
    If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
    Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
    Kernel Extensions in backtrace (with dependencies):
             com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
                dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
                dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000

                dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
    Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
    So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
    Good luck,
    Clinton

  • Black screen on startup MacBook Pro

    I am using a MacBook Pro IntelCD with OS10.5.4 all has been working satisfactorily till today. Today when I boot up it displays the grey screen with Apple logo, then spinning wheel and eventually goes to a black screen. Starting with safe boot does exactly the same although it spends a long time, 6-10 mins, in the spinning wheel zone. Booting into Windows is fine and the computer works perfectly.
    Obviously something is wrong with Mac OS. Is there something to try before having to re-install the OS. Thanks for your help.
    Mike

    Is this black screen with white type that eventually ends with a command line prompt or just a black screen? If the former then the computer is booting into Darwin or single-user mode. If the former then see these two discussion threads for a possible solution:
    Computer booting into Darwin Fix
    Apple - Support - Discussions - Booting to Darwin-BSD Screen
    If the solutions proposed in the above do not help, then you will have to reinstall OS X:
    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    Repairing the Hard Drive and Permissions
    Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

    And I have contacted support as a reseller there and they took care of me with no problems
    And very quickly
    Please advise

    The fix is to replace the logic board.
    Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
    If it's too late for your unit to be repaired free of charge, and you don't want to pay for the service, you may (or may not) be able to stop the panics by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
    Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.

  • How do I fix a black screen on a MacBook Pro (less than a year old)?

    My daughter was working on her MacBook Pro and the screen went blank.  She has rebooted and tried holding Shift key when rebooting and also Command V.  Neither did anything.  The keyboard is responsive and the computer is sounding/acting like normal except she can't see anything.  She does not have a way to hook up to TV to see if it is the screen.
    Any suggestions?  She is as college without a car and not sure when she can get to Apple store and laptop is required for school.

    If the screen is black throughout the boot process, meaning no gray screen, no Apple logo, etc., it's likely a hardware problem. If she can't get to an Apple store, she can call and Apple will send a box for her to send it in to them. Of course, that lengthens the time it's out of her hands.

  • Black screen with Distortion - Macbook Pro (Retina 15 inch Late 2013)

    Hello.
    I don't know much about computer problems like this, hence why i'm here but yesterday my Macbook Pro started to get pixel size flickering snow with some flashing horizontal lines. It kept functioning fine although this was happening.  Then later when I opened it up I discovered it had become much worse only showing the below screens when the power is turned on and nothing more.
    It's as though everything has been compressed to the left hand side and then fragmented across the rest of the screen.
    Any ideas?  It hasn't had any drops or bumps etc.
    Can't get an appointment with a genius...
    Thanks.

    I would take it in, It could be graphix card, display, cable, lose connection.  No easy resolve on your part.

  • Started as a Blank Screen, now my MacBook Pro is useless.

    I have a serious issue that has cost me well over $2,000 now and I am getting ******. I am a programmer and I have multiple projects on my Mac that I have now lost. I do have a Time Machine backup but its weeks old. Didn’t realize Snow Leopard was the new Vista.
    Snow Leopard does not work and I cannot restore my computer back to Leopard. The issue I am having is the blank screen bug that is caused by Snow Leopard. When using 10.6.0 I was able to resolve the blank screen by simply reinstalling Snow Leopard.
    I updated to 10.6.1 and I now have the blank screen and this time my MacBook Pro is unresponsive. For me to get the blank screen all I need to do is put my computer to sleep. When it goes to sleep there is 50/50 chance it will recover. This is the first time it happened with 10.6.1, the issue is now more sever, my assumption is 10.6.1 caused this. This is not a hardware issue; I have already eliminated that possibility. Taking the MacBook Pro to the Apple store is out of the question. They had a Mac Pro of mine for 2 weeks and said it was fixed, when I got it back it was still broken. I fixed it in 3 hours…. They almost broke my raid card in the process. The so-called Apple Geniuses are idiots.
    I’m turning here as a last resort, I’m not expecting to get this resolved but it’s worth a try. In a nutshell, my problems as of right now are:
    1. Mac will not boot – I have a blank screen, like my computer is in sleep mode and won’t wake.
    2. I have a CD in the drive that I cannot remove. I tried all methods to remove it, still no luck. I am about to take it apart to manually remove the CD.
    3. I have already tried resetting my PRAM and NVRAM, no change.
    4. I have tried to use Target mode but it seems useless. I have tried to use every mode to boot that Apple has and still it’s a no go.
    5. This is not the possible nVidia graphics card issue because it’s not just a video problem. I am out of warranty so it may seem a useful escape goat.
    6. I have upgraded my HardDrive and my memory. I have no issues with this hardware, I know the issues are not related to the new hardware installed, I already tested this hardware and this issue only happens on Snow Leopard.
    All that’s let for me to do as of this moment is to get my refund for Snow Leopard and move back to Windows…. I really hate Windows but it’s more stable than Snow Leopard.
    To any that can help, thanks; if not, hope this doesn’t happen to you.

    Using process of elimination, Snow Leopard has ruined my MacBoook Pro. I have tested my HD and Memory in other MBP’s and they work fine. I had no issues till I used SL and it is obvious that it was the cause of the issue. I’m sure Apple will deny this claim….. Be warned.
    I now have a $2,500 paper weight. I’m done with Apple…. Hackintosh was more stable anyways.

  • Black screen when waking macbook pro retina from sleep. Mavericks

    Hi, ever since I updated to Mavericks i've been having this problem when my early 2012 rmbp wakes up from sleep and the screen is black except the time and battery info. When i start moving my mouse around the screen it's still black UNTIL I click and drag on the desktop wallpaper and whatever selection I clicked, my wallpaper will show. In order to actually use the laptop I either have to restart my computer or click and drag all around the computer screen so everything (wallpaper, app icons on dock, apple logo) will show up. Really strange. Not a big problem, but it is really annoying sometimes. Anyone have any suggestions?
    Thanks, Ryan

    well, the sad news is that although there are thousands of people with this issue, Apple is NOT going to recall the computers and fix them. This is particularly bad news for me as I am part of a team that is working with the poor in a devastated area of the Philippines and I cannot afford to get a replacment.
    I don't know what I am going to do when my Macbook will not wake up anymore....
    If anyone has news or suggestions on how to get help from Apple, please forward it to me

  • Early 2011 2GHz Macbook pro distorted blue screen then wont boot, 3 times in last 2 weeks

    I have an early 2011, 2GHz macbook pro (15' model with ati radeon graphics). It was running fine for the last two years. Over the last couple of weeks, following things happen:
    1. I was running on bootcamp windows, browsing and some flash content was open, suddenly distorted blue stripes appear and it froze. Force shut down using power button, turn on again and it wont boot on windows or mac, or recovery partition or from the dvd. Tried for about 4 hours, after nvram, pram reset, it was able to safe boot, then run disk utility to verify and repair the disk, it said that there were problems with hard drive and fixed,then booted normally.
    2. I thought that the problem might be because I was on windows, so took a back up of the windows drive, erased it and installed windows 8 using bootcamp. It ran well for an week. After that, once I connected it with the tv using HDMI to watch a video, after I disconnected it, the screen was garbled over the windows start screen, but I was able to command restart normally. After restart, it wont boot to windows or mac.
    3. After several hours of trying, i was able to boot using the dvd this time, it said it 'can not install mac on the hard drive', erased the hard drive and it was able to install the os (snow leopard). After completing install, logged in to app store to download previously purchased mountain lion. Then ran it to upgrade the os, after the upgrade was completed, at the point when it prompts for apple id and password to set up icloud, it again froze with distorted blue screen. Shut down forcefully. Then turn on again and it wont boot. After the white screen and the sound, it shows the apple logo and spinning wheel for a while, then a bright white screen and nothing happens.
    Can anybody help reading the symptoms?

    I have the Early 2011 2GHz Macbook Pro and I have the same problem too.
    I switched out the logicboard a month ago and today the graphics just went distorted.
    Any solutions? Now I'm thinking it is the Graphics Card.

  • My 2011 13'' MacBook Pro has started to run really slow.

    I have a 2011 13" MacBook pro and this week it has started to run really slow. Specifically it takes about 3 to 4X longer to do just about every task. The only thing ive done recently was update from Lion 10.7.3 to 10.7.4 and a Safari update. Are there any suggestions on what I should do to fix it or on what could be the potential cause?

    Things That Can Keep Your Computer From Slowing Down
    If your computer seems to be running slower here are some things you can do:
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X 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.
    Repair the Hard Drive - Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. 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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    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.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
    If nothing here seems to help, then reinstall Lion:
    Reinstalling Lion 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.
    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. 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 main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

  • I have a very tiny, fuzzy black speck on the screen of my Macbook Pro 15".

    I have a very tiny, fuzzy black speck on the screen of my Macbook Pro 15". It doesn't resemble dead pixels I've encountered in the past (it is only visible behind a white or brightly colored background), and I'm positive it isn't sitting on the surface. The computer is only a year and a half old and my software is up to date.

    Hi austinbread,
    It is hard to tell exactly what your issue with the MacBook Pro’s display is, but it is possible that there is a pixel anomaly. See this article for further information -

  • 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. I also tried to hold the both buttons Start and Home button for 30 seconds etc....nothing happend...so I need your useful and helpful tips to start my Ipod...I don't no what should I do that it starts again..
    with very best regards
    WAQAR   

    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!

  • 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.

  • My screen on my MacBook Pro blacks out constantly. If I press on the bottom left side of the MacBook, I can keep the screen on. I have been placing a small note pad to keep pressure on the bottom in order to keep the screen lit up.

    You should try taking the battery out and putting it back in, but then if that doesn't work, you should take it into your Apple Retail Store and have a genius at the Genius Bar take a look. That seems like a hardware problem to me.

  • 2011 17" MacBook Pro freezes for over 5 mins on user password

    Hey everyone,
    I installed Yosemite on my 2011 17" MacBook Pro. Since then, after a period of my computer being on or after sleep, it appears that the process that handles login using my user password hangs for a bit and then proceeds to work.
    On the login screen, after I enter my password, the focus is drawn off of the password field, and then the computer just sits for what seems to be about 5-7 minutes. This also happens when OS X asks me to enter my password to install / uninstall something; the login window just sits there and does nothing.
    It doesn't happen right after a restart, and it seems like it happens more often after the computer goes to sleep and wakes back up, or has just been running for a while.
    A couple other possibly related problems is that my system will sometimes just start to slow down and every app will slowly become unresponsive, sometimes to the point where I have to use the power button to do a hard reset. Also I've noticed that my system won't remember that I set my screensaver to "never" but will reset itself to "15 minutes" (which is annoying, because after I come back from the screensaver, my system takes a long time to log back in).
    I can't do a system reinstall right now, and I've tried to do PRAM resets and disk repairs. Maybe I'm googling the wrong words, but I've searched and I can't find threads with my exact issue.
    Can anyone help? Thanks!

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities 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.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. 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 main menu. Select Restart from the Apple menu.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, 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.
    5. Reinstall Yosemite from Scratch:
    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.
