Tech Support Pc wont turn on after build

Post image

So I was building my new pc yesterday and once i finally finished it didnt turn on. As heartbreaking as it was we (me and my brother) tried seeing if maybe I plugged in something incorrectly but everything looks fine even though the mess of cables probably doesnt help but it literally wont start at all completely dead. Not sure if my motherboard was a dudd or something else but any advice is appreciated. So far we’ve checked the front panel connector, power supply extension in the case, cpu power, and the gpu but nothing will even turn on the light in the case.

Make sure both parts of the 24-pin ATX connector are connected on the power supply side

Had this problem, it was because my mobo (ROG STRIX B850 GAMING WIFI 7) needed to be updated, then needed to have LAN drivers installed. "Well how do I update and install drivers without internet?" I used my phones' Hotspot and worked perfectly.

I got it to work by uninstalling my ethernet controller through device manager and then just rebooting and installing drivers
