I'm building a new computer and it has been a minute since the last time I made one. I've installed the motherboard (Asus STRIX Z270-E GAMING ATX LGA1151), memory, SSD and HDD, CPU Cooler, and CPU. I go for a test boot to see if all is well so far. I've checked the connections, unplugged and re-plugged, but when I start it up the motherboard turns on (LED activates) but the case fans (2)/ CPU cooler fans don't spin and the bios doesn't pop up on the monitor (nothing pops up, it's not connecting at all). Need some help on this. Thanks in advance and all parts that are with this build are below.
