x570 Aorus Master stuck on blinking clear cmos

[Semiconductor15]

Hi, up until yesterday I was perfectly fine with my system (listed below) doing stuff as always. While I was playing a game system just shut down completely no sign of life even on/off button led on mobo (which stays lit while the system is turned off) was gone. I tried to restart nothing happened. I did some googling and tried stuff like unplugging psu and all the cables from the mobo, clearing cmos, taking off the cmos battery, waiting for a while and such but no result.

 

After all these, I am stuck in a state that just clear cmos button blinking nothing else. As a last resort, I tried q flash plus thing. I took off everything from the mobo all the cables, cpu, gpu, ram, ssd, etc. 
Just plugged the 24pin and 8pin power cable and plugged a USB on the white USB port on rear IO (as instructed in manual with the right file name and USB format etc. btw I downloaded the latest bios version which is currently F30). When I turned the power on, the same thing just blinking clear cmos button and q flash plus button also does not do anything. 

 

It would be perfect if someone can helped in desperation right now.
