This dual bios mobo got bricked during a bios upgrade flash process. I managed to re-programmed the bios (v.F20) using that CH341a tool. And it worked. I re-booted into bios and into the OS several times with success even after putting everything back into the case. Next morning, powered on and all I get is fan stops, fan re-starts till I get one short beep. Fan spinning but no display.
I have replaced CMOS battery/RAM/PSU/monitor/power cables.
Only thing unchecked is the CPU chip (7th gen) which is new BUT obviously worked the day before.
I tried shorting the m_bios, no luck.
So it can only be the BIOS or somehow the b_bios has re-flashed the older bios version which does not take a 7th gen CPU.
I tried shorting the m_bios (1 and 6), no luck.
What am I missing?
