My Late 2009 27 "iMac has problems and vertical stripes

Hello friends,

I'm looking for help with my iMac. A week ago the display began showing scattered pixels and it froze when switching between desktops. At this point, I restarted and the screen came with vertical lines, made of strips of color slightly different at intervals across the screen. There are five of these lines. Sometimes the lines persist through start upward and stay on the screen. Sometimes, they disappear and reappear later. Sometimes my computer freezes with lines and the apple logo and a progress bar. They stay when I boot in safe mode and my bootable backup as well.

Abdesslem Support recommended a Genius Bar apt. To diagnose the prblem. I took it, by explaining that I thought it was a video card or the issuance of the logic board. Genius Bar says it's probably bad Ram. I went home and started to test the ram. I tried each piece individually and as a couple. I always had problems. I ran Memtest 86 and Rember each for hours at a time and got no errors. I tried to boot into Apple Hardware Test, but it never loaded. The internet says I should boot from my installation discs, which of course, I have more.

I fear that the cost will be too prohibitive to repair and so far, each local repair company I called said that they repair the vintage iMacs.

Any advice?

This is again an iMac 2009 end 27 "with 16 GB of RAM DDR3 1066 Kingston into 4 sticks of 4.

Try to replace your RAM with all the new RAM. You can check that the CrucialAdvisory tool, or OWC. Both are reliable suppliers. If the new RAM works fine. If not, return it.

    Lotus should work in 8.0, but victory 8.1 is forced out to all users, so you should get it shortly.  It is downloaded via the window updates so if you want to get earlier just check for updates

  • Reference Dell 5130 has 3 light vertical stripes in the print area.

    The printer has three light vertical stripes which seem to affect all the colors too.  Place the solid blocks for each of the colors (red, yellow, blue and black) k each color block exihbits light strips on the left of the printed area, one near the Center and the other near the right side when printing with a margin of 1 ".  Changing the margins does not affect the position of the light areas, only if they fall within the print area or not.  When the background is white no line or band appears in this area.   Any thought as to the cause and the cure.  All consumables are reporting that they have at least 15% life left or more.

  • Skype has problems and closes after opening.

    When I click on Skype, I get connected. However, after a few seconds, the program will immediately say: "Skype has stopped working." and will have to close. I installed and re-installed Skype several times, without success. I tried to go to the Roaming folder to change the settings there. Did not work.

    Now, I had this problem for about three days, and I'd like to get it fixed so I can start talking with friends again.

    When I went to check my version of Internet Explorer, the program didn't open either. I got the idea to go down and uninstall IE 11, using IE 10 instead. Once I did, after I restarted my computer, Skype has started working again. I have not had problems, but if I do, I'll be sure to report it. Thanks for the suggestion to check my version.

  • I have an iPad 2 Air, version 9.2. Whenever I have delete an app that has problems and then try to reinstall it, it simply returns to the iCloud as I sent it, with the remaining problems. How can I reinstall the app without problems?

How can I get the application in a "clean" State, under its previous problems?

    Deleting an application does not send it to iCloud, and it deletes your system actually.  The problem is that the defect in the application has not yet been set by the developer, and your relocation simply recovering the defective version of the app on your iPad.  Expect that the developer of the app has a new version until you try to reinstall.

  • My laptop has problems and I can't use most Windows programs on my computer

    Original title: nothing works

    I turned on my laptop Vista today after using it only not for about a week and he is haunted by the things go wrong. The network in the status bar icon indicates that the network is disconnected, even if it is connected properly. I can't use most Windows programs including:

    OneCare, Windows Update Services, the event viewer, Defender, also Outlook will only open in safe mode. These are only the ones I've tried, so there may be more.

    I received a 0x8007043c error message when you check the update of Windows, but most of the time that it does not open.

    As I said, I haven't used the PC for a week or two and I have Windows Update set to automatic, so it can update itself, but I do not remember.

    If anyone has any ideas, I would be very grateful for your advice!

     

    Thank you.

    Hi Anna_Alice,
     
    Follow these steps and check if persists it to the question.
     
    Step 1:
     
    Problem could be related to infection of virus/malware or spyware. I wish that you run a full scan using your security software in order to remove the malicious software.
     
    Step 2:
     
    I would have you done SFC scan on your machine to determine if the problem related to the corruption of the system files.
     
    Step 3:
     
    If the steps above do not work, I suspect involvement of conflict of software of third party causing the problem to occur. I would like you to put your computer in a clean boot State. Clean boot helps eliminate conflicts of third party software.
     
    Note: Follow step 7 to your computer as usual.
     
    Step 4:
     
    If none of these suggestions/steps help, do a System Restore to the point (Week) where the computer was working normally.

  • Your pc has problems and needs to be restarted.

    Pls advise me what to do.

    I have hp pavilion g6

    and there the windows operating system 8

    processor i3

    4 GB of ram

    hard drive 500 GB

    AMD graphics card.

    This error is often shown with the same files listed below.

    How can I fix this.

    The minidump files showed several different stop error, most of whom (7A) KERNEL_DATA_INPAGE_ERROR stop error which may indicate a problem with the hard drive or hard drive controller.

    One of the mistakes stop was a DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) referring to the hpdskflt.sys which is a pilot DriveGuard.

    What I would suggest is to first update the Intel storage driver by installing the next update:

    http://h10025.www1.HP.com/ewfrf/WC/softwareDownloadIndex?softwareitem=ob-114125-1&CC=in&DLC=en&LC=en&os=4132&Product=5340271&sw_lang=

    Then, install the following update for DriveGuard:

    http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?cc=us&LC=en&softwareitem=ob-124661-1

    If the problem persists consider running a chkdsk/r on the C drive.

    Run a chkdsk/r has the potential to take a long stem, and as precautionary measure General, back up all critical files beforehand.

    If the computer is still under warranty, I highly recommend to contact HP on the question to get help.

  • JavaScript has problems and opens windows of manysmall that I have to close before I can do anything. How can I fix it?

    This problem occurred for several months. I've updated Firefox several times, but the problem persists. Very frustrating!

    Well, unfortunately, it didn't is not simply how to do it. Generally, you must disable all non essential and see if that helps. Or disable them individually if you are very patient.

    On Mac, you can disable extensions individually on the page modules. Either:

    • Command + shift + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. (In Safe Mode, they could all shows them as disabled already, so I'm not sure, that you can test without closing Firefox and restart in normal mode.)

  • T400: Problem and FIX for UK Conexant Audio Driver for Windows Vista and XP (4.92.2.0 2009/04/23)

    Hello

    I installed the new drivers Conexant for my T400 (the driver is also for R400, R500, T400, T500, W500, W700, W700ds, X 200, X200s, X 200 Tablet, X 301) yesterday.

    This morning I had to adjust the smart-audio feature works correctly with my helmet of docking station for VoIP calls. The control panel SmartAudio applet would work well. It crashes.

    Today a .net developer and that it is a .net application I got it debugged in Visual Studio. The problem, apparently, is that the folder "C:\Program Files\CONEXANT\SAII\en-GB" does not exist on my machine. Of course, it is true. The solution is to go to "C:\Program Files\CONEXANT\SAII" and copy the contents of the "en-US" folder to a new folder "en-GB".

    Just thought I'd share this incase anyone else has problems and so Lenovo can fix if all goes well the installation. I suspect it will be wishful thinking, to provide them with real ENGLISH values for resources in en - GB instead of corrupt English which is probably in the American version resources

In the P & F pref panel, I tried to install the printer using all 3 protocols (Line Printer Daemon - LPD, Internet Printing Protocol - IPP and HP Jetdirect Socket), I plug the verified address of PPI, I selected the generic Postscript printer and the HP 6300 series drivers and nothing works.

    What is happening here? Thanks in advance.

    "I decided to update the BIOS on my Toshiba laptop Satellite A100 - 712 PSAA9E to the latest version available (6.00).

    The installation is completed normally (went through all the steps, wrote to all 21 blocks) without any error, but after the reboot, I noticed that it is now displayed at the Toshiba logo screen.

    The blue progress bar moves twice but got caught then about 1/3 of the way through.
    To see how bad the damage was, I Press esc at the beginning of the POST and saw that it gives me the right Version of the BIOS (6.00).

    He also told me that "no TPM or TPM has problem" and "2039 M RAM Passed system."
    It then displays the message "Press to enter SETUP" (which makes the message disappears, but otherwise doesn't do anything.

    If I press F2 during the Toshiba logo screen, it replaces the bottom with "Please wait" message and nothing happens"

    Hello

    I posted this already in another view about a similar BIOS problem.

    To me, it seems that something was wrong during the process of updating the BIOS, and if you're lucky, the flashing of the ROM BIOS might help you.

    As far as I know that you would need a BIOS version of special rescue and the drive to reflash the module ROM that you do not and therefore, you will need to contact the ASP in your country for assistance.

    This isn't a real solution that you expect, but it s an advice how to get a solution
    This is why I would recommend contacting the ASP in your country for the control of the laptop

  • The superdrive in my iMac (21.5, late 2009) refuses to mount new audio CD. It is very good with cds that have already been imported into iTunes and Ditto DVD. But the new CD is ejected, which means that I can't add anything to my music library on a cd.

    The superdrive in my iMac (21.5, late 2009, running OSX 10.10.3) refuses to mount new audio CD. He sees the cds, which have already been imported into iTunes (12.3.2.35) and same DVD. But new (IE back to the computer) cds are ejected, which means that I can't add anything to my music library on a cd. Any help would be appreciated!

    First try to reset the SMC & LANDAU 2 - 3 times back to back by LANDAU and Intel iMac SMC resets with all devices disconnected.

    If that does not resolve the problem, go to your local office supply store and get a CD/DVD cleaning kit and use it. If this does not work, then the SuperDrive is end of life and should be replaced. Many users with iMacs older everything just get external DVD readers, if you need to do this, I recommend you contact OWC (www.macsales.com) and they can direct you to one that fits your needs.
