Hello Grant, it is happening from a few days ago a week or two, i was needing confirmation but that what it seems to me too, without knowing the language posted above about the crash report, sometimes when i´m in full screen mode looking at a video in You Tube, the System shut down and re-star again alone, strange it happens only in you tube. I had swapped this graphic card no long time ago, cause the other one was also dead. pretty frustrating. if you can recommend a good graphic card for this mac: it is as you can see : System model name: MacPro2,1 (Mac-F4208DA9),

Best Regards

Thank you

Thanks Grant

Cheers
