Update,

Keyboard is working on the Bios,
Mouse is not working,
and the CPU fan are slowly,
I have 9 / 10 volts on the output on the cpu fan header and the case fan header.

on the first time i have no screen at all,
The winbond chip was burned but it is replaced with a new one, it is the same W83977EF-AW
after change we have picture on the screen and the bios is working,
and starting Lynx, but after starting i have the error GMM 275 > NC in nood.
and the system are nog responding,

on that the keyboard is not working anymore, the mouse must by working immediately after starting.
but between the start window and the error its also not working.


So how trouble shootiing this problem ?

The mouse is working, with a other ps2 working fine, so the mouse was also broken,
After doing the steps on this youtube video, it is working again.

Thank you.

The cpu fan speed, we have it for now resolved, we have the fan now connected on the chassis fan header.
