Powering on for the first time with this MB and a Pentium CPU the PSU fans come on only for an brief instant (less than one second) along with the CPU cooler fan and then stop with no further activity. It will do this each time I turn the PSU off and back on. I tried two other PSUs with the same results. It's a 750W Corsair PSU and a Pentium G3258.
Have you ever experienced this during a build?
There was only an 8GB DDR3 RAM stick and a 120 GB Sata SSD connected at the time. I tried to remove the RAM and SSD but no change. I am assuming at this point it is a bad MB or CPU but not sure what to try next. I'm planning to return the MB to Newegg and will get a replacement but wondered if anyone else has any ideas whether it could be something else I'm missing. I initially connected the 24 pin CPU and 4+4 CPU cable along with the molex 12V for the extra PCIe power. I'm not sure if possibly plugging in the molex PCIe cable was a mistake since I didn't have any GPU's connected yet at the time. I unplugged it right away after the initial power on.
