I have processor: i5-6300U
Trying to update graphics driver.
Current driver: Intel(R) Graphics HD 520
I did the auto-scan thing that Intel have, and it showed me the windows 10 64 bit DCH graphics driver. However, when I try to install, I get the error "not compatible with your processor".
What driver do I need please?
You need to remove ALL previous versions of the graphics driver, unless you are a laptop. If you are a laptop, you can use only the drivers provided by the laptop manufacturer.
If not a laptop, use this procedure. https://forums.intel.com/s/question/0D50P00004Fm2ngSAB/how-to-install-the-dch-driver?language=en_US
I also suggest you download and install DCH driver version 126.96.36.19918 or newer. These versions (finally) have support for over-installing older non-DCH driver versions.
