Hello!
Regarding your GeForce Now issues, servers are generally operational, so your problem is likely client-side. The blurry image and games minimizing on startup, especially with driver reinstallation errors, point to a corrupt or conflicting graphics driver installation. First, resolve that driver error (using DDU for a clean uninstall). Then, in GFN settings, manually set a high custom bitrate and ensure display and in-game resolutions match to combat poor image quality. Also, check for background applications or Windows settings that might be causing games to minimize.
