If anyone is having issues with black screen after installing the shaders try this.
My pleasure bud. You are going to need to right click on your desktop and select
1. NVIDIA Control Panel
2. Select Manage 3D settings
3. Make sure High-preformance NVIDIA processor is selected as you may have integrated graphic available with that laptop. Here is a picture for you bud.
