I assume that you have installed new RAM in your MBP.
It would be helpful if you indicated the EXACT model/year MBP that you have.
What the the RAM specifications that you are trying to install?
Ciao.

  • Last week, I had no problems streaming my MacBook Pro to my sony Bravia with a logix hdmi cable. I came back from holidays and now it doesn't work anymore.  What settings should my computer be on and what settings should my tv be on?

    I did not use my computer yesterday, and now all of a sudden, Firework does not open at all after clicking on its icon or starting as a program. I did not download any upgrades or anything else, and I have Norton 360 version 3. I can open Internet Explorer, but that's not my default browser, so I have no problem with the Internet connection.
    What could be the problem, how can I restore my browser without losing my bookmarks, settings, etc?

    If you close Firefox, then start Firefox in Safe Mode, does the problem still occur? For instructions on starting in Safe Mode, see [[Safe Mode]]. Extensions can sometimes be the cause of problems. If the problem does not occur in Safe Mode, then you can disable your extensions one-by-one until you find out which one is causing the problem. See [[Troubleshooting extensions and themes]] Update Firefox, see [[Updating Firefox]]

  • I upgraded to OSX Mavericks and the CMS of my website, which is built with joomla, does not work any more.What could be the problem?

    It displays many lines of error messages, all starting with Deprecated... and the boxes, in which I am supposed to introduce the text, are not active.

    The reason files on the USB flash drive appear to vanish could be many, but it's not normal for spontaneous file deletions to actually occur. Verify that your Finder preferences are configured to show external disks on the Desktop:
    Uninstall Intego VirusBarrier. It is capable of doing nothing beneficial and could even be causing the problem. Be certain to follow the developer's uninstallation instructions and confirm all its remnants are permanently eradicated.
    When encountering unexpected behaviour on a Mac the very last thing you should suspect is a virus and the very last thing you should consider to solve it is using any "anti-virus" product. Doing so is nearly guaranteed to make things worse.
    A PC can't read Mac formatted volumes unless you purchase software for that purpose.
    There is neither a method nor reason for resetting USB ports.

  • After the upgrade it's impossibille to use search engines, everytime firefox stops working/reacting. What could be the problem?

    Als ik gebruik maak van een zoekmachine, krijg ik wel de resultaten, maar is het niet mogelijk om een pagina te openen. Firefox reageert dan niet meer. Het maakt niet uit welke zoekmachine, bij iedere gebeurt dit. Dit is direct na de upgrade begonnen. Via een andere webbrowser is het wel mogelijk om door te klikken. Wat kan hiervan de oorzaak zijn?

    You are on Windows 2000, you do not have a "Firefox" button, and should consider yourself to be fortunate in that you still have menus and don't have to do anything to get the menus back instead of the "Firefox" button. (The same applies to Windows XP users).
    Use the "File" menu to get to Import. You are not on Windows 7 or Vista, and don't have to put up with the nonsense added for Aero.
    If you want the "Firefox" button you can get it with View -> toolbars -> (uncheck) Menu Bar. The menu bar and the "Firefox" button were supposed to be mutually exclusive (which is impossible in some cases without being incompatible).
    Once you are using the "Firefox" button ...
    Use the "Alt" key to view the menu bar (temporarily) containing File, Edit, View, History, Bookmarks, Tools, and Help. On Windows 7 and Vista, the menu bar was hidden by default in Firefox 4 and above. These menu items are more or less available under the "Firefox" button which has the most used of the built-in Firefox menu items available in a different format.
    To get back to having menus again. "Firefox" button -> Options (second column) -> (check) Menu Bar
    You can make '''Firefox 7.0.1''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6)].

  • My selection & direct tools are not working properly. What could be the problem?

    I can't select my selection & direct selection tools from my tool bar. The shortcuts are working but even when an object is selected I can't edit the color of the object. When the mouse hoover the selection tool icon it does not highlight like the rest of the tools. The mouse is working fine in other Adobe applications and I never have a problem before. T his just happened suddenly. I read one post where the person had a problem similar to mine and I applied the suggestion that was given of changing the Theme for Windows 7 but I still have the same problem. I'm working in CS5 and my OS is Window 7. I will appreciate any help. Thanks

    My iPhone 4 turns off (crashes) after accesing any apps, It work fine when plugged to charger (power supply). I tried all troubleshooting steps suggested by Apple but it doesn't work. I backed up my phone. I restored it several times. Even I re-installed iphone software. Also I restored it as a new iphone but doesn't work. What could be the problem and what are the availble solutions?

    We can't know if there's a "fixture" because we can't examine your phone.  But Apple can.  Make a Genius Bar appointment and get your phone evaluated.

    I have a speaker with I phone 30 pin dock, it use to work fine but i am not getting error saying accessory not supported,how i can determine what could be the problem
    i am getting the same error with my rf transmitter that i use in my car

    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - Did this start happening after an iOS update? Sometimes an iOS update will break compatibility.
    Sometimes this works:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings      
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                 
    iOS: How to back up                             
    - Restore to factory settings/new iOS device.

  • HT4970 My reminders app will not want to create reminders for me. What could be the problem, how to fix it? Thanks in advance

    My reminders app will not want to create reminders for me. What could be the problem, how to fix it? Thanks in advance

    Lol idk I updated this iPhone right when I got it because it said there is a new update so I installed it as soon as possible and there is no plus sign over there. I don't know how that happened maybe its something in the setting do you think you know? And when I ask Siri to create me a new reminder and I tell her the time and everything she says are you sure you want to create this reminder I press confirm and then she says I'm sorry but the reminder you are trying to create can not be crated.

  • My website created with Iweb and hosted on mobileMe is not showing well on all computers. What could be the problem ?

    My website created with Iweb and hosted on mobileMe is not uploading well on all computers. What could be the problem ?

    I got a chance to look at it on a PC.  Totally hosed up. It loads incorrectly then parts of it go blank.
    I have a site that is based very much on one of the built-in templates and it works fine on the same PC.  It contains only text boxes, image placeholders, and images with "picture frame" borders.  Nothing fancy, no overlays, no extra code or anything. I haven't looked much at the other templates so I don't know if yours is mostly a template or how much you may have modified one or what tricks you may have done to get the look you wanted.  Whatever it is, IE does not like it.  Unfortunately, you can't really ignore them as was suggested; they make up a large part of your audience.

  • HT1199 my mac pro will not install updates or new software such as printers what could be the problem

    I have tried to complete updates and install software and for some reason it will not update or install new software such as a printer.  What could be the problem

    A reset may help. Tap and hold the Home button and the On/Off buttons for approximately 15-20 seconds, until the Apple logo reappears. When the logo appears, release both buttons.
    No content is affected by this procedure.

    I have no idea what the "freezer fix" is, nor why anyone would think temporary exposure to cold will somehow fix a hardware issue with a 100% solid state device.  Also, actually freezing your iPhone may very well itself cause damage.
    If you dropped it and wifi immediately failed to work, the odds are you inflicted physical damage to it - perhaps the antennae connection internally.  You could try a simple reset and see if that helps, but if not, you need to take it into Apple for an evaluation and diagnosis.
    If it has internal damage, since you dropped it, your warranty no longer applies.  Apple does not repair iOS devices, the merely swap them for factory refurbished units (and send your damaged one back to the manufacturer in China for refurbishment or recycling).  You would ahve to pay the out of warranty replacement fee (look on your country's Apple web site, under support for the iPhone for fees).

  • I have an Apple wireless keyboard that will not turn on, even with new batteries.  The contacts seem fine.  What could be the problem?

    My wireless keyboard will not turn on despite new batteries.  It is about 8 years old. The contacts seem to be good.  What could be the problem?

    Hi elljohnson,
    It is important when replacing discharged batteries in the Apple Wireless Keyboard to make sure the new batteries are oriented correctly. See this article for directions -
