Problem with Hp dv7 1270US/Nvidia 9600m gt.

Hi guys,

I recently updated my OS to windows 7 64 bit ultimate edition on my HP, with nvidia 9600m gt . I installed the driver from the nvidia website, the 186.81. It seemed to be working okay, but suddenly after a couple of hours the screen just started to go black then come back and i would get this message.
.

Does any one know what this means ? and how i can fix it ?

I would try to roll back to a later driver from Nvidia and see if this keeps happening also check the event viewer and see what else it says maybe its just one file for the driver that is corrupt and needs reinstalled

where would i be able to roll back ? or download older drivers ?

Just download an older set of drivers thats the easiest way to go back one version.

O ok, i searched for old drivers on google, but i cant seem to find them. would you know where i would be able to ?
