Dear All,
Sometimes my system hangs on POST with code b2. Press keyboard and mouse no reaction and also no display on screen. I need to restart several times and then it can work again.
Now my BIOS is 3.1 and my board is X470 Taichi, please help!

Dear Koikun,

Greetings, this is ASRock TSD.

Generally, debug code b2 means that system is in starting process.

Please try to press [F9] load BIOS default and then [F10] in BIOS page to observe if it will work.

Also please try to install only one memory module to different slot by turns to verify.

Thanks!

All the best,
ASRock TSD
