My gpu changed :( help i am serious

[BrickMation]

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.

Just downgrade your GPU drivers back to the stable version.

Not always the latest GPU drivers will work for all people. I've also downgraded my GPU drivers and after some time, when even newer version comes out, i upgrade to that instead, completely skipping the bugged version.

1. Look up your current Nvidia driver version.
2. Download the older version from here: http://www.geforce.com/drivers
3. Uninstall your current Nvidia drivers with alongside of Nvidia Experience.
4. Install the older version of Nvidia drivers you downloaded in step 2.
