oh... who knows what a problem it could be:
my system is:
Gigabyte GA-Z77X-UD5H
Gigabyte GTX 660 Ti 2GB
RAM 16 Gb
The system works great very long in all the applications before I start Aperture or Photoshop. After that the system start to work very slowly or even freeze. But not immediately: at first everything works fine. But in a short time performance falls, interface changes not smoothly and system can freeze or show me low performance till I reboot it. If the system freeze at the time when the music is playing it continues to play without problems, but no keys on a keyboard are working and I need to press reset button to restart. It is only happens if I work with Aperture or Photoshop.
- I tried to install system like Slugnet recommended.
- I tried to install 10.8, update to 10.8.2, install only cuda + nvidia drivers.
In both cases, the result is the same.
I'm going crazy...
