• 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!

• 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.

• 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.

• 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?

• 23 "all-in-one: Black squares randomly on the screen

  All of a sudden screen has randomly black and square rectangles covering the screen. Cannot find the logout button because there is a black square, cannot click to go to the next page, impossible to use Google as the question box has a black screen. Windows 8.1. Help.

  Was not comfortable making the black squares of reset, so downloaded Chrome, went away (so far). Can assume it is Internet Explorer. Have other problems with IE.

• Satellite A60-122 - does boot and the screen has lines on it

  Hello!

  I have a Toshiba A60-122 PSA60E model. Pentium 4 HT. 1 GB of memory, 80 GB hard drive. BIOS 1.7.

  The problem is that it hangs on until the Windows XP logo appears, then the choice of Windows is displayed, I try safe mode, but does not work either.
  And then decided to have a specific format but still the same problem, and even the recovery CD does not either.
  I noticed that the screen has lines on the subject. Toshiba Logo appear when booting, you can see the columns of the row.

  Can someone help with my problem? Any idea?
  And by the way, I want to update my bios to 1.9, but the problem is that I can't find the traditional BIOS update on initialize to top.

  Thank you.

  Do you have these lines of the screen on an external monitor too or only on the screen LCD internal?
  It sounds like a hardware problem, but if you can determine if it s a LCD or motherboard problem. Check it!

  And by the way, what do you mean if you say that it doesn't work? You can see something on the screen and you get a BSOD?

  Maybe the problem is with the motherboard or HARD drive. You can test the HARD drive by using the Drive Fitness Test (Google is your friend).

• When I open Roxio it changes the screen resolution of 256 colors at a very low resolution b and the program will not work.

  My Roxio VHS TO DVD movie editing program has worked on my laptop Toshiba Windows 7 system before I reformatted.  Now when I open Roxio it changes the screen resolution of 256 colors at a very low resolution b and the program will not work.  When I close the program Roxio the resolution of the screen reverts back to 256 colors.  Control of program compatibility tells that it's incompatible, but the program worked on my system before I reformatted.
