Splatty2k Level 1 Level 1

Hello,

 

my recently used bought iMac 27 won't boot up. After the greyish Apple Logo and spinning circle, the screen just goes grey.

 

Before these probles occured, the iMac froze randomly with a greyscreen while I was working. After a reboot everything was working again.

 

 

If I try to boot with the System DVD (10.6) the same symtoms occur.

 

I did reset the pram, start with cmd+s, safe mode (3 beeps!), unplug it for a while, eject the dvd, perform sbin/fsck -fy (3 times OK)

 

 

mid 2011, i5 3,1, 8gb, 1gb graphics card

 

randomly it shows a bluescren instead of login screen

 

 

 

Yes, I read this article. http://support.apple.com/kb/TS2570

 

Is my RAM damaged?

Like i said, probably a logic board failure.  Bring it in to better understand what is wrong, although you'll probably need a new computer, juding by the seriousness of the problem

    Probably not the ram.  Because the issues persist with the boot CD, you don't have software issue.  The logic board may be failing.  I would recommend bringing it into service to get a free assessment, and go from there.

    Don't the three Beeps in safe mode boot mean "faulty banks"?

     

    That's why I tried OEM Apple RAM today, still the same symptoms.

     

    cmd+alt+R runs for 10 Minutes, then the spinning circle is showing. when a graphical user interface should occur, there is only a blank grey screen left. (just like normal booting)

     

    I assume either the GPU or logicboard is fried.
