Random Freeze - mouse icon is spinning aroun #iATKOS #ML2

Hi all,



actually I'm happy with my hackintosh, except one issue.



First my configuration:

Mountain Lion 10.8.2

Gigabyte Z77X-UD5H - Bios v14

ASUS DirectCU - Nvidia 660ti

16GB Ram

System SSD - OCZ Vertex II 120GB

3xHDD 2x1TB 1x3TB



Sometimes the system freezes, especially when I start Applications like Capture One or Premiere.

What do you think?

GraphicsCard? SSD?



I thought GTX660ti is supported OOB in 10.8.2



Any hints or tipps?



Many thanks to the community
