I tested everything possible. Just not working. Very weird.
I removed everything and only connect the PSU ATX cables to the mobo and as well as CPU fan.
Even just alone, CPU fan not running. Tested to connect it to chassis fan connector and CPU fan is running.
Even as such, I try with a proper run with OS hdd etc this time. CPU fan was running in connection to chassis connector and CPU "looks" like running, but I'm not seeing anything on my screen.
I think really no choice den got to bring down SLS tomorrow
