So a day ago, after an update, my computer basically just decided to change the gpu by itself, so i have a powerful gtx 860m, and a bad integrated intel home 4000 gpu, so it changed the gpu, to the integrated one, and i've tried everything from the nvidia control panel, but nothing is working, it says i have the gpu but it wont work, should i deactivate the integrated gpu. and if i do. Can i activate it again, please answer as fast as possible because i'm litterally scared frustrated and nervous, like i'm serious and scared for my pc.
