hello, hello, i recently bought msi gt60 one 403, online from xoticpc.com . i am facing this following disorder after a recent update of Nvidia GTX680m driver from nvidia's official site: the laptop has stopped detecting nvdia graphics card after I installed an update from windows update and started using the intel hd 4000 graphics card. I tried uninstalling and re-installing the drivers but none worked. While reinstalling the error popped up stating " No supported hardware found". Later I restored the notebook from windows restore disc but still the problem remained same. Same error message popped up while re-installing the driver. Now the card isn't listed in the device manager under Display Adapters which wasn't the case earlier. under system devices in the device manager, i see Xeon® processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port - 0151 what is this?? even dxdiag is showing intel hd 4000 as my default card. attached are some screenshots showing the above issue. what is the issue and how to resolve this problem??PLEASE HELP.
