MacBook Pro, randomly Windows 7 doesn't start and screen goes blank

Hi, I installed Windows 7 (Ultimate 64-bit) using the BootCamp on my MacBook Pro (MBP) i7, mid 2010. Installation was successful without any issues. This is my first Mac and, for now, I primarily use Windows on my MBP. The problem: After selecting Windows OS, randomly, Windows doesn't start and the screen goes blank. When this happens, most of the time I have to press the power button twice and press the Option key again to restart in Windows. Sometimes I have to hold down power button for several seconds to turn off MBP, then power it back on to start over. Windows 7 seems to restart on second try every time.
I can tell when the screen will go blank and Windows will not start, when the blinking cursor does not appear on upper left corner of the screen. Also, I enabled Windows OS Boot Log and nothing displays when this happens.
I took in my MBP, twice, to local Apple store Genius Bar and I was told that it was a Windows problem and I must purchase AppleCare Protection Plan to get help resolving the blank screen. It was explained to me that AppleCare had Windows experts who can help with resolving the issue. Therefore I purchased the AppleCare Protection Plan and spoke to AppleCare directly and still no resolution.
Any help you can provide would be greatly appreciated. Thanks in advance.

There is a forum specifically for Boot Camp, this is a general MBP forum and most of us don't use Boot Camp or Windows. The link to that forum is:
http://discussions.apple.com/category.jspa?categoryID=237
Apple does support Boot Camp however if your problem is with Windows Apple does not support a Microsoft product. You would need to contact Microsoft for help.

  • MacBook pro when windows 7 has startup problem and Mac os doesn't work

    I installed windows 7 on my MacBook pro and it did work well. But now windows has a startup problem and "startup repair" couldn't solve it, so I can't use both Mac os and windows and my laptop has become completely useless. Any suggestion?

    Reboot and hold down command-R at the sound of the chime, that should take you to the Lion recovery partition, if it does go to disk utility and see if you have an OSX partition at all.

  • TS2570 My 2010 MacBook pro gets stuck at the apple start up screen

    I think I've tried almost everything possible and my computer gets stuck at the apple start up screen with the loading bar under every time I shut the computer down and restart it. I've tried all the resetting, trying to do the apple hardware test (which never worked), and so many other things that I can't even remember everything that I've tried. Could someone out there possibly help me?

    Yes. I turn it on like I normally would. I hear the chime and everything. It looks like it wants to start up and it acts like its loading. Then it just gets stuck when the loading bar gets to right about the middle.

  • My MacBook pro wont wake up from sleep. The screen is blank at all times, but I can hear the fan for 5 sec then everything stops. Please help! I don't kno what to do.

    My MacBook pro is about 3 yrs old. It is a 2008 model right before the new design came out. Recently I closed it up which puts it to sleep and a couple minutes later when I opened it up the screen stayed blank but could hear the fan running but then the power clicked like it was shutting down and I could hear nothing more. My power supply is working and I have already tried resetting it. Can anyone help me? I don't live exactly near a Mac store to get help.

    Before resorting to an LB change-out, try this, as it has fixed many of the "silver-key" Macbook Pros with wake-from-sleep issues:
    1) To get the computer running, do an SMC reset. Instructions here:
    http://support.apple.com/kb/HT3964
    Your MBP model uses the first option under the subhead, "Resetting the System Management Controller (SMC)"
    2) If you get it running, go to System Preferences > Network and select your Airport connection
    3) In the result main pane, click the "Advanced..." button.
    4) You should be looking at a window with multiple tabs at the top; the "Airport" tab (far left) should be active---if not, make it so.
    5) There is a panel showing "Prefered Networks." Use the "minus" button below that window to eliminate any networks that you don't need to access on more than a weekly basis. I'm down to two: the home Airport Extreme Base Station and the network for a museum at which I volunteer once a week.
    5) Click "OK" and close System Preferences.
    Now try letting it sleep and see it if wakes up.
    When this happened to my Late 2007 MBP, I used Console to read system.log and found that, on waking, the compuer was looking for the wireless network at a lodge where I'd stayed weeks earlier and miles away. Clear the morass of old networks and keeping the list short has completely cured my wake-from-sleep issues.
    The steps I listed take less time to do than to read, and are within the ability even of novice Mac users.
    If that doesn't work, you may need to seek professional help. If you take it to an Apple Store and they recommend a logic board replacement, ask about a "Depot Repair." Instead of replacing the logic board on-site (which will whack you to the tune of US$700-1100), they send the computer to a central Apple refurb facility that fixes whatever they find wrong for a flat fee of about US$315 (last time someone reported using the service here). Turnaround is about one working week, and people who have taken of this service have reported being very pleased with the outcome.

  • I have Windows 7 Pro, 64Bit. Itunes works fine except I can't go to the ITunes store from in the software. It starts and then goes blank page. I have tried all the fixes and had a IT group working all day on this. Not fixed. Any suggestions?

    Using I Pod NANO. Installed I Tunes on Windows 7 Pro, 64 Bit.
    Software works fine. Only problem is that I can't open up the
    Store page from in the software. It just shows a blank screen.
    Looks like it starts but then just freezes.
    IT department worked all day. Reloaded software, set up
    security, checked msconfig files. Tried all sorts or revissions.
    Nothing works? Yet it works fine on my Windows 7 Home edition?
    ANYONE have a clue. This Apple software is not the friendliest!!
    This is very frustrating for something so simple to use!
    This used to work. Upgraded to 10.3.3.. No good. Tried other revisions,
    No Good! Can't purchase music or have the website fully pull up at all
    from I Tunes.
    Appreciate any help if some has been through this. My service that
    I have for IT had to give up. 6 hours of things they tried. Nothing worked.

    You would get better response from the iTunes community forum.
    Have a nice day!

  • I have an Epson printer on a Wifi network. Windows 7 desktop and and HP Win 7 laptop (my wifes) print to it just fine. My MacBook Pro running Yosemite won't detect it, and I have the latest driver installed. No problem when I had a Canon...

    I have an Epson printer on a Wifi network. Windows 7 desktop is running the network, and my wife's HP Win 7 laptop prints to it just fine. My MacBook Pro running Yosemite won't detect it, and I do have the latest driver installed. I didn't have a problem when I had a Canon Pixma on the network, but when I replaced it with the Epson nothing seems to work. I go to add a printer to the queue and only the FAX function of the printer shows up - not the WS-4530 print function. Does anyone out there have any suggestions?  Please??? :-)

    Hi Kelly,
    As someone who has to print from my Mac to a networked printer at home all the time, I can certainly understand how frustrating it must be to have that fail to perform as expected. Let's see if we can get you up and running.
    I would suggest that you troubleshoot using the steps in this article -
    OS X Yosemite: Printing troubleshooting
    Start with the section titled Check the network.
    Thanks for using Apple Support Communities.
    Sincerely,
    Brett L 

  • Can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts.

    can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts (10.6.3 retail). Lion installer starts normally. What's a problem?

    I have the same trouble, I try installing rEFI but when I try start my Pro from DVD doesn't recognize.
    Can I start from USB Memory? with files from SL DVD? or have some thing else?
    I have original DVD of SL 10.6.3, if I buy the latest stable version, can I install? or the EFI firmware with Lion change again?
    I try to use Lion, more than one week but I can't, and some app that I use for my profession, doesn't work, I really need downgrade to SL.
    Really Thanks for any help.

  • My macbook pro (August 2010) keeps freezing when apple mail starts up. This happens every 2nd time I turn on my Macbook Pro. This forces me to hold down the power button to restart my Macbook Pro. Does anyone else experience this, and is there a fix? Thx

    since upgrading to OS lion, my mac book pro (2010 August) keeps freezing (non responsive, requires restart) when i turn on my mac and the system is trying to open apple mail. while apple mail is attempting to collect new mail, the macbook pro freezes. this happens every 2nd time i try to start up my computer. this only started happening after i upgraded to OS lion. please let me know what I need to do to fix this. being forced to restart every 2nd time i turn on my macbook pro has been very frustrating. not sure if apple mail is also the cause of my macbook pro for being very slow during start-up (on the occasion the computer doesn't freeze).

    I am having similar 'freezing' problems with many programs (Mail, Safari, iTunes, etc.). I have done a clean install of Lion instead of an upgrade when it came out. Perhaps something went wrong with my install? I'm thinking about wiping and reinstalling.

  • Upgraded from 10.6.8 to Mavericks last week on my MacBook Pro running the 2.4 GHz i5 and it's painfully slow on start-up- I mean, 5 minutes or more, to be fully functional... Is this normal?

    Upgraded from 10.6.8 to Mavericks last week on my MacBook Pro running the 2.4 GHz i5 and it's painfully slow on start-up- I mean, 5 minutes or more, to be fully functional... Is this normal?

    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.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks 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.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

  • Macbook Pro Randomly Crashes w/ Most Recent Crash Report

    Hey, everyone.  Hopefully someone can help me with this one.  Within the last two months, my 15" Macbook Pro has been randomly crashing on me, normally right after a boot up.  I currently have version 10.6.8.  What may happen is that I'll be 5 minutes after I've booted up the computer, the screen will go black and every time that I've had music playing during this time it skips.  I've checked just about every software update I could think of and I seem to be up to date with everything and/or any updates I do install don't seem to affect this problem either way.  I have past crash reports after this same incident happened as well, so I can provide those if needed.  I must add that I do take this laptop just about everywhere, so it is totally possible that I've just handled the machinary too rough.  Thank you very much to whoever can help.

    I have a very similar issue too. I have a MacBook Pro mid 2010 with ML on it and i take it everywhere, i mean it. i have between two and 5 random crashes a day where i get a black screen and immediately later i get a grey screen attached below before it starts booting.
    i've been saving the crash logs and started to notice a trend in which both
    com.apple.driver.AppleUSBUHCI and com.apple.filesystems.smbfs
    are the star players in the last loaded and unloaded kext. below is a snippet from one of the crash logs
    last loaded kext at 322317713273: com.apple.filesystems.smbfs          1.8 (addr 0xffffff7f977af000, size 229376)
    last unloaded kext at 335446223059: com.apple.driver.AppleUSBUHCI          5.1.5 (addr 0xffffff7f963dc000, size 65536)
    does any one have some clue as what may be the problem?
