Thank you for responding. I tried using DirectX 9. Seams to work for a bit (around 2 hrs), Then I get the same error. Tried CC cleaner, that did nothing, all my drivers are up to date. I also tried disabling my SLI with DirectX 11. Works for a bit then same error. Its strange because I been using the same rig for about a year and never got this error before. There was a new driver update with NVIDIA a bit back. Do you think that might be the cause?
