I noted your system has hybrid graphics on your laptop. It is necessary to install the latest BIOS, chipset driver and the latest graphics driver for Intel® HD 4600 and NVIDIA GeForce GTX 965M.
Pre-build systems such as your Alienware 15 comes with customized drivers by your pc manufacturer. Our generic drivers available in our website might not work in your system.
I suggest you to install the latest driver provided with Dell support website.
From this Intel® link, you can find our latest generic driver.
