I just checked that and it's enabled so is the SMART thing.
What version is your BIOS? I had a similar situation with an Asrock board. When legacy USB was enabled in BIOS, it took a long time to check for legacy devices. Disabling the legacy USB resulted in quick boots but not recognizing my keyboard or mouse at bootup... so I could never enter the BIOS. The solution was to update the BIOS to the latest version where they had remedied the USB code. After that, I could leave legacy USB enabled and boot up time was normal.
The temp problem is probably not related. But one thing at a time.
