I can not control my ARGB lighting for my mobo and AIO.

This pattern matches a known Windows 11 issue involving some RGB-related drivers or software components with names similar to inpoutx64. Microsoft documented that these components can interfere with system behavior after certain updates, including RGB-related functionality and game/system stability.

Since reinstalling Windows only fixes it temporarily, the more likely cause is the RGB driver or controller software being reintroduced and then taking control again.

Recommended path:

1. Check whether a background lighting controller is overriding Windows lighting control.
   • Open Settings > Personalization > Dynamic Lighting.
   • Expand Background light control.
   • If another RGB controller app is listed above the Dynamic Lighting Background Controller, move it to the top only if that is the controller intended to manage the device, or adjust the priority so the expected controller wins.
   • Also check Compatible apps in the foreground always control lighting and turn it off if foreground apps should not override lighting.
2. Test with Windows Dynamic Lighting enabled or disabled.
   • In Settings > Personalization > Dynamic Lighting, toggle Use Dynamic Lighting on my devices.
   • If Dynamic Lighting is off, devices use their default non-Dynamic Lighting behavior.
   • If individual device cards appear, configure the motherboard/AIO-related device there and verify whether device-specific settings are overriding global settings.
3. If the problem started after a recent Windows update and the system has RGB-related instability, check for the inpoutx64 driver.
   • Microsoft identified an issue where RGB-related components with names similar to inpoutx64 can cause problems.
   • A documented workaround is to temporarily disable that driver in the registry.
   Warning: editing the registry is risky. Back up the registry first. Steps documented by Microsoft:
   • Open Start, type regedit, and open Registry Editor.
   • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\inpoutx64.
   • On the right, open the Start value.
   • Set Value data to 4.
   • Close Registry Editor and restart the PC.
   Microsoft notes this can cause unintended behavior such as loss of RGB features or issues with RGB control software, so this should be treated as a diagnostic step.
4. If lighting sliders in Windows do nothing, assume another RGB app is still higher priority.
   • Microsoft specifically notes that when brightness/effects do not change the device, a background RGB controller app is likely taking priority.
   • Recheck Background light control after each software change.
5. For the fan-control part of the issue, the available context does not provide a Windows-side fix beyond the RGB-driver conflict guidance. If fan settings and motherboard/AIO lighting both stop persisting after shutdown, that points to the same controller stack or motherboard utility path rather than a clean Windows installation issue.

A practical next step is to isolate whether inpoutx64 is present and whether changing Dynamic Lighting/background controller priority changes behavior before reinstalling Windows again.
