Windows updates microcode to version 07.
Check it with new CPU.

Nothing happen. The screen doesn't turn on. CPU fan doesn't run. Only hear small sound of HDD spinning

I do with CMOS Battery remove for 5m to reset all setting + Only 1 RAM on Dimm 1 + Without Battery only apdater
It isn't microcode issue. BIOS mod can't help you, because it isn't loaded by a motherboard at all.
