Hi
If you have a desktop graphics card you can go to the gpu card manufacturer or chipset manufacturer such as amd or nvidia or intel
For laptops you usually have to go to the laptop manufacturer as the driver is designed for the graphics chip and lcd display system
If you need windows 10 driver and cant find it then maybe windows 8 version will work
Obviously the device driver must match the operating system version and 32 or 64 bit
Usually the device driver will not install if it does not find the correct hardware and operating system
