Computer fails to boot – CPU Fan starts and stops with flashing yellow/red lights

Video of cpu fan

Moved houses recently to an old house. Tried plugging in my PC and turning it on (video above) and it won’t boot. No boot screen at all. I tried removing the gpu, SSD, and tried using each ram stick individually to no avail. Tried reseating all wires and cmos battery. I have an aorus x570 elite wifi motherboard but can’t find any info on what the CPU lights mean (if anything)
