It is important to say that OEM drivers include special features that will work specifically for your computer. This is why installing the driver from the Computer Manufacture is very important.
You can try installing our generic driver but it does not include the special features from the OEM design. The conflict between the two graphics controller is because the system was preconfigured by the Computer Manufacture to use the hybrid graphics system with special configuration on the drivers.
If our driver is not working fine for your system, my recommendation is to access the Computer Manufacture website and get the special driver for your computer.
