I have a hp pavilion elite desktop model e9160f that has started going black and nothing works but a forced shutdown. I t said "Nvidia windows kernal mode driver version 320.49 has stopped working (and has recovered but when it does it just goes black again and freezes). I tried a set back to an earlier date and 3 different drivers but no luck. I am thinking the original driver might work as I think it updated for the first time before this problem. Please help if anyone knows how to fix this short of putting in a new driver board. thanks so much.
