Jun 21, 2012 1:46 PM in response to amandreamartinoby BGreg,You should run the Apple hardware test to see if it picks up any hardware issues. You'll need your original OS X disks to run it. Run the extended test, and if it comes back with no issues, run it again. Sometimes it takes more than one run to find a problem. Each test may take 30 minutes to 2 hours, so don't panic if it takes awhile.
One other option ... if the hardware test finds no problems, you might reload the OS X 10.6.8 combo update. That has all 10.6 updates in it, and sometimes can fix funky system problems. Download from the Apple support site. Use Disk Utility to repair permissions first, apply the update, repair permissions afterwards, then run Software Update in the event anything else needs updating.

Jun 22, 2012 8:38 AM in response to BGregby amandreamartino,Already done 2 tests... No problem found! But my gpu temp sometimes reach 65/70 celsius degrees! I need to use iStat Pro to set minimum fan speed to cold a little bit my gpu... For example now it is 50/55 celsius...
If it is an hardware issue, why would have to reinstall combo update? I will try it later...
My Mac sometimes crashes with Linux Ubuntu and Windows 7! Not only on Snow Leopard and Lion!
I've read similar situations on this forum... But most have a Macbook Pro, not a single graphic card iMac!

Jun 22, 2012 8:53 AM in response to amandreamartinoby RRFS,As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

- Shut down the computer.
- Unplug the computer's power cord and ALL peripherals.
- Wait 15 seconds.
- Attach the computers power cable.
- Wait another 5 seconds and press the power button to turn on the computer.
- It is the 5 second timing that initiates the reset.

Jul 1, 2012 7:14 AM in response to RRFSby amandreamartino,Thank you for replying me! Ok, I've followed all of your suggestions... Cleaned the dust using vacuum cleaner, even in the ram bay... Done SMC Reset...

My gpu temp was 54 degrees... **** it, I was simply surfing the web... Not advanced graphics renders, no video editing... No gaming... Just surfing the web...
Can Apple change this faulty Mac?

Aug 30, 2012 9:32 AM in response to RRFSby amandreamartino,It doesn't work... Do you have other suggestions? This problem is making me hate Apple... I think that is seriously an hardware issue, but I don't know how to fix... Sometimes when I use Windows gpu driver crashes and recovers itself, sometimes this doesn't happen!

Aug 31, 2012 4:42 AM in response to amandreamartinoby amandreamartino,I can't believe that talk to an Apple techician costs 49 euros... I've paid 2000 euros for this "powerful" computer that can't even play some opengl stuff... I'm very disappointed, Apple... I have 1 iPhone, 1 iMac and two iPod Touch... But I don't think I will buy Apple products again...
Please, help me fixing this problem...

Aug 31, 2012 5:27 AM in response to amandreamartinoby RRFS,I'm sure we all feel your pain here because we are all just Users of Apple products trying to help other Users. It does sound like you have had a hardware failure.

Sep 1, 2012 5:22 AM in response to amandreamartinoby Radiation Mac,I think at this point you have pretty much eliminated the other possibilities, so it looks like you have a failing hardware component in your iMac. Having said that, you can basically either pay to have it repaired or possibly save some money on a different unit by considering a "refurbished" iMac from the Apple Store online. We're sorry your going thru this difficulty, but in the real world electronic devices have finite lives, and computers, INCLUDING PC's, tend to last anywhere from two to five or six years on average, in my experience. So this is not just an Apple problem. We wish you the best in your decision.
Hope this helps

Sep 2, 2012 6:39 AM in response to Radiation Macby amandreamartino,I don't think so... If you have a PC you can simply change your GPU... Is very simple to do...
Please, my 9 years old pc (agp 9200se) didn't ever had similar problems...
If you have a moment, take a look at this thread...
https://discussions.apple.com/thread/3938355?start=0&tstart=0
This problem could be releated to Lion update... Could it be possible?
Thank you for your help!
