IMac late 2009 - 5 yellow bars on the screen - sometimes...

Hi all..

I recently bought an iMac late 2009 really nice second hand.  It worked wonderfully for a few weeks and I was about to become a mac convert.

All of a sudden things have changed.  I pulled to the top of the machine first thing the morning only be greeted with lines to the bottom of the screen and a stall on a white screen.  The next day, it worked fine for a while.  Then the problem comes back for an hour or two.  Then back to yellow bars.

I pulled up to my PC and started researching and found suggestions that this could be a graphics card problem.  After some time of reading and discovery, I pulled the top of AHT, and he advised me that there is actually a problem with the machine, and it's a sensor on the HARD drive.  Then, I would expect an additional error that could somehow link to the screen and absolutely nothing.

Now, I know that historically the 27-inch late 2009 iMac screen / GPU has been examined by several different sites and forums but it is now an old machine and I don't know what to do.  What is a HARD drive failure?  Seems very unlikely but the only error listed... The flaw is GPU displayed on AHT down?  If this graphics card has received a "reformatting of oven" at a given time in its life and Ive been sold a dunce?

Any advice would be great.  I don't have an Apple store near me and I don't know if they would even look at a machine this old.

Help, please... My brief relationship was positive that ended quickly in tears!

  • Upgrade of Windows 8 has changed my graphics card driver, & now I get vertical bars on the screen.

    Upgrade of Windows 8 has changed my graphics card driver, & now I get vertical bars on the screen, sometimes flashing. It is sometimes difficult to use the screen, especially when it has a dark background. It is a HP Desktop quad core with card Nvidia GEForce 9600.  I tried to roll back the driver, but that didn't help. I assume that the driver I need is no longer available. I also went to Nvidia to try to find a better driver that would eliminate this problem, but no luck.  Before, this came with an update on Vista, & I could correct in the way to roll back the driver. Any help would be appreciated.

    Go to www.nvidia.com and download the WHQL 306,97 drivers updated successfully.

    With the installation of Windows 8, Microsoft provides only the "bare" minimum drivers in order to complete the installation of Windows.

  • Mid-2009 MBP memory is compatible with the iMac late 2009?

    Hello

    I just upgraded the memory for my MacBook Pro (from 2 X 2 GB 2 X 4 GB)... I was going to sell the used memory space but realized that I might be able to add to my iMac late 2009.  How will I know if it's compatible?  Currently the iMac only has 4 GB as 2 units but is expandable to 16 GB and has 4 slots available.

    Forward a response and thanks in advance.

  • iMac (late 2009) 27-inch vertical streak on the right side

    iMac (late 2009) 27-inch vertical streak on the right side. Oddly enough it is still there even on the gray splash screen. How much is it? I tried restarts it, Vpram etc, but still there. Always in the same place. Is a graphics card out or the display itself. Should I make an appointment with an Apple Retail Store?

    Strange, strange! This mysterious line disappeared miraculously se today!

    I am delighted, but at a loss for why it appeared and why he disappeared.

    The only idea I have is THAT HEAT could have something to do with it.

    I look forward to any comments on this mystery.

  • Can I put a Seagate FireCuda drive in my iMac late 2009?

    Apple Hardware Test (AHT) says that my SATA drive, 1 TB in size, has a problem.  Nothing specific indicated. The code given is: 4HDD/11 / 40000000:SATA (0,0)

    I was testing because of the prob trying to get a good download of macOS Sierra.  Looks like I need to replace a hard drive first.  I have an iMac late 2009 with a Core i7 quad core, 16 GB DDR3 1067 Mhz ram and ATI Radeon HD 4850 graphics card.  I can put a SSD in this unit or am I stuck with the Barracuda drives.  I'm looking for FireCuda readers and like what I see and read about them.

    If you want an SSD, then I highly recommend:

    • Samsung 840.
    • OCZ ARC100 and other models.
    • OWC 3 G SSD.

    The foregoing is all compatible and should work well. Your model only supports SATA 3 Gb/s speeds due to the controller, so don't waste your money on more expensive discs of 6 G or 6 Gbps because they work faster than a car of 3 G. If you decide on a 6 GB drive, however, they must be compatible as they work on the slower bus of 3G.

  • my 27 Imac late 2009 became very slow

    My 27 Imac late 2009 became very slow - I think especially after I've upgraded to El Capitan. Otherwise, everything in the computer works perfectly and I m using only 200 I have the 1 TB. Onyx and other tests can't find anything wrong. I mainly use my computer for word documents and to manage his photos about 30 000. The internal memory is 2 x 2 GB. Does anyone have any suggestions of what I could do to speed it up? Thank you.

    I wish I had an answer, but all I can do is rather echo to your problem. I have a 19 mid-2007 "iMac, contributed to the maximum with the RAM, 1 t disc hard less that half full, who did the same thing - he has worked with El Capitan until I updated to the latest version. Once that has happened the machine became so slow as to be unusable. It would take ten or twelve minutes to record a mouse click. When I restarted the machine, it took 32 HOURS to start (Fortunately it isn't my main Mac production).

    Last week, I tried all the remedies of common sense - by removing unused software, keeping an eye on the activity monitor (there is nothing fancy here), etc. Finally, I did all the stuff start, PRAM, run utilities disk (no noted problem) and even tried to reinstall El Capitan to a bootable USB I did with my first Mac, the reinstall, but seemed not 'take' somehow - he wanted to repeat the installation procedure again and again.

    I use the little Mac for Internet, e-mail and (as Karlis2) deal with some of the oldest pictures in my files - I'm sure that I have pictures on Time Machine, so I'm not too worried about it, but this was the first Mac way back in the day, I bought with my money and I'm a little sentimental on and would like to resurrect if possible... I wonder if there is a way to restore the operating system to an earlier version and it would make a difference?

    On this virtual path, it is not possible to say with certainty what the problem is, but I assume that the display may be defective.

    For testing purposes, you can connect external monitor to your laptop to see if everything is OK there.
    Anyway, what you need to do is contact the closest service Toshiba and let check your laptop.
    Warranty is still valid?

    Hi Emma,

    Have you checked under Applications > Adobe Creative Cloud.

    There should be a shortcut if the installation went well.
