Why is my Colorful BATTLE-AX B450M-T lagging at startup?
When trying to hit the main menu, the motherboard had this weird hesitation during the low-level driver stage. Boot times were swinging wildly between 30 and 55 seconds, which made me seriously doubt the compatibility of this board. I first tried disabling Fast Boot in Windows, but that actually pushed the boot time up to 60 seconds and the random black screens persisted—I was totally lost. Then I flashed the latest BIOS version from Colorful and forced the boot mode to pure Legacy. Checking the boot logs, I saw the hardware initialization sequence was finally optimized. Interestingly, after the update, my USB devices failed to initialize on the first try until I manually disabled the old CSM support in the BIOS. With the chipset temperature sitting steady between 42℃ and 47℃, the boot process became buttery smooth. Using firmware to kill these conflicts is a tedious grind, but it fixed the freezing issue and the system responsiveness feels like a whole different league now. Saved the final config in BIOS.
