Hello everyone hope ill get some solution ,
Asrock taichi x399 was not showing any sign or display and all chassis fan was not working first so i tried to remove CMOS battery and fan started working but gpu fan was running like jet engine at full speed
and no display at all no beep , so i decided to flash bios via flash bios USB from back side of flash bios switch i followed the exact process which mentioned in manual , but the green light on motherboard and switch is keeps blinking it supposed to be stop after flashing i waited for long from 2 hrs to whole day still nothing happened ,
i asked to ( DUBAI ) they are saying " we dont provide warranty for USA shipped product ask to (usa ) " and amazon us saying " we work independently please ask to " then i mailed to "Asrock " many time but no response no support nothing so
i hope ill get some response from here and solutions as well
