Thank you very much for all the support. I have finally solved reinstalling MacOSX from a Combo Update. I think ity was a corrupted driver. Now this is my system configuration (as was time ago)

Quartz Extreme should always work on that mac. Try resetting the PRAM, and the PMU.

hank you very much for the suggest. I reset PRAM and PMU (unplug all cable, wait and re-plug cable while pressing ON button, release and start again).

Sadly nothing has changed.

I also reset NVRAM (Command+Option+O+F at startup, then reset-nvram, set-defaults, reset-all), but nothing.

I have heard of a phantomatic SMU or PMU button reset on the logic board... any suggest for it?

Thank you again for the help.

I'm not entirely sure where it is, if it exists, but i will check for you and see if I find anything.

Resetting the SMU button is in one of the last steps in this guide: http://support.apple.com/kb/TS2094

Both my mac-minis developed the "Quartz Extreme not longer supported" problem. I started my project on one then switched to the other. Reinstalling the system fixed this problem for me. It's a tedious fix but I was on a deadline and none of the other "fixes" were working for me (like changing the display settings or restarting) Plus I ran out of computers to switch to. I was surprised that this problem goes back to early 2008 and Apple has yet to address it in any serious way. I did an exhaustive search and finally came across the re-install fix here.
