Hi, I have an Aspire E5-573G with Intel i3-5005U @ 2.0GHz
RAM : 4GB
Graphics: Intel hd graphics 5500 and nVidia GeForce 920M
I was getting green dots all over the screen with Intel graphics driver so I tried switching to nVidia but for some reason could never do it as it kept saying "you are currently not using a display attached to nVidia GPU". So I reinstalled windows but still had the same problem.
I contacted the customer support and they told me to update my BIOS from V1.17 to V1.37. Now I am not able to boot into UEFI mode or to my factory settings as it says '"no bootable device" and in legacy, still my PC is using Microsoft Basic display Adapter instead of NVidia and as a result I cannot adjust screen brightness or play any games. As soon as I install intel graphics driver, screen goes blank and I can't do anything.
Note: In UEFI mode, my BIOS tells me GOP version: Intel something and in Legacy mode its: Nvidia GPU
Please help. Thanks in advance
