HDMI and WIFI not working

[Silas666]

Hi I got a question...I tried everything till now and I have read the Thead a thousand times but I still don´t know what to do...
MacOS Sierra on external HDD
Acer Aspire E5-771
Intel Core i7-4510
Ram 16 Gb
Graphics: Intel HD graphics family and NVIDIA GeForce 840m
Network: atheros Ar956 wireless and Realtek PCIe GBE Family Controller

Problem: My Monitor which is connected over HDMI flickers when I boot the PC up and the other thing is that my WIFI doesen´t work....I would be incredibly happy if you could tell me exactly what to do....

Thank you
