Pc won't boot up.?

Hello ppl.im having problems bootng up pc.i had done everything for the followings.i checked ddr4 rams.power connectors.m.2 ssd.cpu.clear cmos.Still Nothing.i also noticed that my rgb keyboard and mouse not lit so i look on mobo and mobo rgb lights not on either.even on rear.including lan ethernet led light not on.i think what happen is after i replaced my 10th gen intel cpu the rack that holds the heatsink fell in so i used the magnetic piece to lift the rack so i can screw in the mounts to hold the heatsink.do you ppl think that the magnet is the cost for my pc to malfunction? I looked on my status led on mobo only cpu lit for a moment then dram stay solid light then my pc making beeping sound.my processor should be fine because i just got it today.i even use my other processor.power supply.same results.nothing.i think i just killed my mobo because of the magnetic part.hope this help.thx everyone.
