So I log in to my computer today to see the '3D Viewer' thing that's part of the GPU driver that I haven't taken off my desktop missing. I also saw that the GeForce experience thing was missing as well. I log into the game and I can immediately tell I'm using CPU graphics. I went to go to my GPU control panel to change it back, missing too. I installed the GeForce Experience thing and download the driver, restart, get back on, driver wasn't installed, I did this 2 more times. Then I proceeded to download it off the website, same output. I go to the device manager to see if I can update there and I see a hazzard sign over my GPU. Gives me this in the description 'Windows has stopped this device because it reported problems (Code 43)'. So windows shut off my GPU and won't let me use it. If anyone knows what this means or how I can fix it please tell me because I kind of need my GPU.

Note: I have a NVIDIA GeForce 880M
