Greetings. This machine's fan spins fast when put on.
I've tried to flash it with some Bios files from here and elsewhere but didn't work.
This is the original saved Bios. Please can you clean it?
Thank you.

Thank you for the quick reply of the file.
I've flashed it but it didn't solve the problem. Fan spins fast when power plugged in and no display. Please any suggestions?

Greetings Salimeh. Thank you again for the file. The problem was not solved after reprogramming. Here's an image of the Bios chip on schematic.
When the machine is ON with fan spinning high, the CS# pin is high with 3.3v and the pins 5 & 6 which are clk & Si_Rom are instead 0v with partial short to ground with about 4.5ohms resistance. When off, Pins 5 & 6 have no partial short to ground.

I'm kind of blocked here. That's not normal, right? Where should I look? I've tested the resistors on that SPI line and their values are normal.
