so annoyed rn i installed the NVIDIA Aopen AK79D-400V nVIDIA nForce Driver R3.13 update last night and this morning my living-room PC looked like this on the desktop:

little colored blocks, filckering lines, sometimes a whole strip of teh screen goes green for a moment. it doesnt crash, it just looks horrible. my stomach dropped because artifacts usually mean dying hardware, right? but its suspicious that it started exactly after the update. how do i tell which one it is wihtout spending money? pls help 🙏
