  • Installed new bios and now computer won't boot

    I just installed the new bios for my  HP Pavilion dv6704nr Entertainment Notebook PC laptop off the hp website and now my computer won't boot.  I tried removing all power (including the 3 volt battery) and it still won't turn on.  I Then tried the windows + B keys at boot and still nothing.  I have windows7 64 bit OS and installed the vista 64 bit bios (the only 64 bit bios they had).  Any help would be greatly appreciated.
    Thanks

  • I just updated to mountain lion and now pandora won't work, videos won't work, i can't access my iTunes.... the list goes on. HELP!

    I recently updated to mountain lion and many of my most used programs won't work....
    pandora
    itunes
    hulu
    any vidoes.... says pop up blocked
    somehow I can't change any of my security preferences
    SUPER FRUSTRATING

    So what happens if you go to System Preferences > Security & Privacy > General? Are you able to go there at all? If you are able to go there, can you unlock the preferences using the lock in the lower left and your login name and password?
    If you are able to do this, can you change the "Allow applications downloaded from:" to Anywhere?
    Best of luck.

  • Just installed Mountain Lion, and my Mac won't boot correctly. What should I do?

    So I stupidly decided to "upgrade" to Mountain Lion this evening. I downloaded ML, installed it, and now whenever I try to boot my Mac I can't get anywhere. The apple logo comes up and the spinning wheel below it starts up, but then it stops and restarts itself over and over again. I can boot in Safe Mode and I have verified the disk and the permissions (there were no issues.) Any suggestions on how to get it to boot normally? If it helps, I have a 2011 Macbook with 8GBs of RAM. I did have Snow Leopard before I tried upgrading to Mountain Lion.
    Also, on a side note, I have my original install DVDs that came with my Macbook... if nothing else works, can I use these to revert back to Snow Leopard? I don't care if I have to clear my entire computer, I have everything I need backed up (and not through Time Machine. I just have the files I want.)

    Have you checked that all your apps are compatible with Mountain Lion? Check that the apps are supported > http://www.roaringapps.com If you have apps that aren't supported, start in safe mode and uninstall them. Then, restart and see if Mountain Lion starts properly.
    Another thing you can do is to reinstall OS X again. To do it, hold Command and R keys while your computer is starting and reinstall OS X.

    Of course. You have to erase the hard drive and install Snow Leopard on your hard disk, but first try to solve the problem with Mountain Lion

  • Just uploaded mountain lion and now it won't let me buy Logic Pro X in the App store. Error 100 over and over again.

    I was trying to get logic pro X. It's not letting me purchase it after updating.

    Try deleting the cache associated with the App Store.
    Quit the App Store if it's open.
    Open a Finder window. From the Finder menu bar click Go > Go to Folder
    Type or copy paste the following:
    ~/Library/Caches/com.apple.appstore/Cache.db
    Click Go then move the Cache.db file to the Trash.
    Relaunch the App Store and try purchasing Logic Pro X.

    Dear  MAC-Friends.
    PLEASE HELP ME.
    I am extremely afraid to do something wrong - what will be a failure so I loose all the photos I had in my iphoto library before installing the Mountain Lion.
    I have just installed the MOUNTAIN-LION and now I can´t use my Iphoto-programme without answering the following question:
    Choose another Library ?  ( But I only want the choose the photos which one was in the old iPhoto-Library and not the other photos on the MAC-computer ? ).
    and the other possibility is:
    Create a new Libray ! Which iPhoto-library  ?
    And why create a new and to risq to loose the old photos.
    PLEASE HELP ME.
    Kind regards  FINN GRABOWSKI

    Ok. Let me first ask you, do you have any backups of your files - for example, do you use Time Machine or any other backup system?
    Next, quit iPhoto. In the Finder, go to your Pictures folder. Is there a file there called iPhoto.Library? How large is it? (If it doesn't show the size, click once on it, click cmd-I to see the information). If it's a healthy size (ie, several GB), then that should be your library, and you can double-click it to launch iPhoto. (The application will remember where your library is next time, you can just launch iPhoto normally).
    If that's not the right file, check your Trash. Is there anything in there?

  • I was installing mountain lion and now my macbook pro won't start up

    I was installing Mountain Lion and i restarted my computer and now it won't boot up.

    Reinstalling Lion/Mountain 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/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.

  • I upgraded to Mountain Lion and now my computer keeps freezing.  How to fix?

    I upgraded to Mountain Lion and nowmy computer keeps freezing.  How do I fix this?

    I know you have 10.8.4. I'm asking you to download and install a Combo updater. This is not the same updater used through the App Store when you simply upgraded from 10.8.3. And, before you do that I suggest you do this:
    Repair the Hard Drive and Permissions - Lion/Mountain Lion
    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
    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. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
