Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and they're good too.
No data lines seem to be missing.
Checked resistors and data lines from SIO/KBC to the fan, these are good.
But the SIO/KBC is missing the PWM Signal to the fan.
If I inject 5v to the PWM, the fan kicks in, but the machine will still freezes when loading Windows.
What am I missing ?
Thanks.
