Nvidia 310M problem

[ssdp_20072]

Hi guys,
I have a Lenovo G460 running 10.7.4. with following configuration:
Intel core i5 520M
500gb hdd
4 gig ram
nvidia 310m 512mb

Problem is that the system freezes after a couple of minutes after boot. I looked up the system log and found this:

NVDA(OpenGL): Channel exception! exception type = 0xd = GR: SW Notify Error

The graphic card show up in system profiler with all the info but the system hangs after a few minuted of boot. I can move the mouse but the screen is frozen. I have edited my DSDT in the following manner :

Any help would be really appreciated. Thanks.
