So, I have a 2008 iMac 3.06 ghz with the infamous nvidia geforce 8800 gs graphics card. I game- ALOT. Now, my iMac has failed. The GFX card I think. UPDATE: I'm sad to say that this is happening. As of May 7, 2011, the iMac has been freezing up within 20 minutes of use, the whole computer locks up, the screen flickers once, and it is completely unresponsive except the mouse cursor is movable. Going to the Apple Store today to see what they will do about it. Update: May 8 As of today, they are going to replace the logic board for a whopping $696.50. Good thing I have insurance. I really don't think it will solve the problem as it's the graphics card that I Think is failing, but whatever. I will update again when I get it back from the Apple store. Update: May 12 So I called Apple to see what was going on, they said it turned out to be the hard drive in the process of failing. To me, this was odd due to the fact that I had just had the hard drive replaced 6 months prior.....weird... Anyway, they said they have a logic board on order as a "what if" back up solution. They will transfer my data, so all in all, it's okay (as long as i dont lose my data ). UPDATE: May 13 So I got my iMac today, and it turns out they replaced the hard drive. However, within 5 minutes of getting it home, it went absolutely crazy. The screen started flickering like crazy, lock ups, everything. They're sending me an external hard drive to back up the data, then theyre going to wipe the computer clean,(to make sure it's not a software problem....(?) replace the gfx card and see if the problem persists. If it does continue, then they will issue me a replacement computer. I'm kinda done with the BS though, I just want a working computer at this point. UPDATE: May 22 So I brought the computer into Apple yesterday, and it turns out they replaced the video card. I'm going to pick it up today, they said it's working, and hopefully this is the case. If not, then I will demand a new computer as this has been my 6th trip to the Apple store, and it's not exactly close to my house... Anyway, I'll keep you updated with what's happening.. Just got it back from the store, they apologized, replaced the graphics card, and so far everything is working good. VIDEO AFTER 5 MINUTES OF BRINGING IT HOME FROM THE APPLE STORE: (MAY 13) http://www.youtube.com/watch?v=5x5bbTb2h5U Overall, the Customer Service is FANTASTIC at the North Shore Apple Store in Peabody. Very helpful, honest, and got my iMac repaired within 14 hours... However, the Applecare Senior Advisor(phone calls) "Mike" was a total jerk. He didn't call me back for 3 days...and caused confusion in the whole process.
