Hello, i've had my imac G5 for sometime now and it has recently started crashing on start up, the display goes almost as if it is in 2, which is probably a weird description and then i have to restart, this will happen 2 or 3 times and then it will be okay, it sometimes happens after the machine comes out of sleep also, the machine specs are as follows:

20" 1.8 Ghz PowerPC G5
Memory 1.25 GB DDR SDRAM
Running OSX 10.3.9

I have looked in the panic logs after searching on this site, which is very informative, and they are posted below:

it is the same message everytime the MAC crashes, i'm no expert with MAC's but it looks to me as if there is a problem with the graphics card.

Can anyone help with this?

Many thanks

Stewart

Check out

http://www.apple.com/support/imac/repairextensionprogram/

and see if your iMac's serial number falls into the range covered by this program.

When my logic board was failing it manifested in video aberrations.

That would be the smart thing to do. Logic board problems was what popped into my head first.

It's Mac not MAC :)

Aw, you're mean!:rolleyes:

I was going to say that but I figured I'd leave him off this time as his stress level is probably high enough already.

Have you installed any memory, hardware or new programs recently. Is there any pattern to what you are doing when you get the panics?

thank you very much for your replies, i shall make sure i call them Mac and not MAC from now on :)

the kernel panic described always happens on start up, i've probably installed lots of things recently to be honest as i use logic pro for music on the machine and am always installing plug-ins every other day, i havent turned the machine upside down to check the serial number as yet.

but thanks very much for all your helps and replies, cheers

To get the Serial Number, just go To "About This Mac" in the Finder Menu Bar and click on More Info.
