Lenovo T430 clean Bios needed

Hello. I have Lenovo T430 which does not boot correctly. I tried to replace CPU with integrated GPU, but problem isnt solved. So i have BIOS files, which MAYBE can be faulty. Can somebody give me clean, and working bios files( 4mb and 8mb). Motherboard is NZM4I-7. I will post mine original files. Bios is unlocked.
Thanks.
