Is the BIOS already aligned with the latest release? Have you attempted to update drivers manually using the installers on the mainboard manufacturer site? https://www.gigabyte.com/Motherboard/B55...er-chipset Did you review the Windows Device Manager for any unrecognized devices that may require drivers?

Hi Dreckssackblase, Yes, I flashed both motherboards with the latest bios revision (14e) and installed all the drivers. Windows device manager does not show anything unrecognized. Thanks, Stefano

I re-connected the GPU power cables, they seemed okay. I also verified the gap between the connectors and it was nonexistent. Then I turned on CSM support in the BIOS. After rebooting, the screen failed to turn on, so I had to shut down the PC via the PSU. The positive part is the UI no longer stutters and input keys repeat properly. Still, between reboots Windows repeatedly asked for the BitLocker key—it was odd. I discovered that W11 requires Secure Boot enabled when CSM support is active, which conflicts with my settings. So I turned off CSM support, which restored the stuttering BIOS issue but allowed me to enable Secure Boot again. Unfortunately, none of these adjustments resolved the GPU default fan curves, which remain unresponsive. I still depend on Afterburner. My hypothesis is that the GPU fans automatically shut down in BIOS due to Windows or the NVIDIA driver adjusting the fan curves. Changing the motherboard might have triggered a conflict with the GPU's VBIOS. I plan to wipe the drives and reinstall Windows 10 to test, though I might spend another 40 euros on an ASUS ROG if it helps. For now, I’ll try this again just out of curiosity, then reset everything and order that ASUS. Stefano

I switched the motherboard using an ASUS B550-F but problems persist. Now, to run games like Doom Eternal, I must set the GPU power target to 50%. Could this be related to the PSU? I own a 2019 Corsair RM850x and have even tried connecting two PCIe cables simultaneously without success. I’ll bring this up in another thread.
