I think i need a modded driver for my gtx980m, i have an Alienware M18x R2 and i installed the new graphics card along with the A11 unlocked bios but when windows installs the NVIDIA driver it says in device manager that the device has stopped.  My laptop is running off of the default graphics and not the new card. Any help would be greatly appreciated.   My Hardware ids are: PCI\VEN_10DE&DEV_13D7&SUBSYS_05501028&REV_A1 PCI\VEN_10DE&DEV_13D7&SU
