Question New build woes

Jun 4, 2020
Hey guys, Im new to the forums so I hope this is the right place for this post

So I just built a new rig, specs are:
Amd Ryzen 7 3700X
ROG Strix B450f Gaming
32gb (4×8gb) DDR4 2133MHz from Corsair Nvidia GTX 1080 8GB
Corsair VS650 PSU

Given that the mobo doesnt support gen 3 ryzen I had to flashback the bios to update it to the latest so that the CPU would run but this is where the problem begins.

All peripherals worked fine until the computer reset itself after the BIOS update. After restarting the computer lights up, all fans spin and no alarms from the computer but the peripherals dont work.

Just looking for some advice on what to do because I'm currently pulling my hair out and dont have the cash for costly replacements/bringing it to a pc store. Thanks in advance guys.
