    Hello.
    I'm new to the forums here and the reason I have signed up was to ask for help. The answer to the problem is quite logical: a logic board replacement.

    Here's my situation:
    I own a 24 inch iMac 8,1 late 2008. Around last month, it got hit with the black screen problem. Seems to be a graphics card failure (NVIDIA GeForce 8600M GT).

    Well, as always (and what I've read on the Internet) the repair will skyrocket to approx $1000. This is freaking me out. It's quite the sum of money. However, after thorough research I stumbled upon an apple article addressing this same issue. Turns out that the failures were due to the NVIDIA card and that Apple had a 4 year warranty for it (ended December 17, 2012). This problem with the NVIDIA GeForce 8600M GT had come under a class action suit so will I be still warranted the damages? The document specifically quotes 'unlikely' but hasn't said impossible. I shall link you all to the article. So will I be under warranty?

    Thank you all in advance. I look forward to you people responding.

    I recommend upgrading your MXM GPU.
    No LB replacement nesseccary.

    Thank you. Since you have suggested this instead of a logic board replacement, I will assume that this repair is a whole lot cheaper. May I know how much it is for? Also, whatever the repair may be, I want to know if I can be warranted as I have a faulty graphics card.

    Hmmmn. That's very relieving to hear. I would guess that the repair would be around $200. However, would the GS be warranted too?

    I really appreciate you all replying. You guys have been very professional and accurate.

    Also. Could somebody help me determine whether it is my graphics card causing a problem or would it be the mobo?

    Thanks in advance to the people who have read my description:

    I remember the day it blacked out. I was on Skype talking to a relative. Suddenly, the screen goes black. I can see the pixels lighten up but they are all black. I tried hard rebooting. When booting, the computer would boot up as normal. Then, the computer would respond for a minute or two and then it goes all haywire with the pixels. The pixels just flash all over the place. The computer goes blue or black after a while. I tried reseting the PRAM and tried safe rebooting.

    I also have one more idea of what may have caused the problem. It is pretty unlikely to me that this is the problem. A month before the mac went crazy, I had purchased 8GB of RAM (4 each slot). It was from crucial, a pretty reputed and trusted company with pretty premium prices. The computer would show and register the RAM when I clicked 'About This Mac'. However, online I read the computer has a max capacity of 6GB. I overlooked it because the computer registered the RAM (or so it seems).

    To end, my question is: is it the GFX, the mobo or the RAM?

    Thanks in advance and I look forward to you guys' passionate and professional - like help

    Are you planning on doing the repair your self or getting a worker to do it.
