Can a mobo kill cpu?

[Discreet]

My pc suddenly shutdown and when i tried to turn it on it wont have display and no keyboard. Familiar? This is the indication that you might have a faulty ram or dirty so me being know what to do i clean the ram, use only 1 ram and using different ports but nothing changed. I tried to reset the bios by removing the cmos battery, guess what it also didnt work. I also checked the psu and it is fine. The fan, led works. I lose hope that the problem might be the motherboard or sa cpu itself, until an idea came up to my mind i realized that me and my brother's pc have the same processor so i think that to know if my mobo works or the cpu, i exchanged our cpu and when i turned on my mobo with my brother's cpu it didn't work so i conclude that my mobo is bad or dead, until i turn on my brothers mobo with my cpu in it and unfortunately it still doesn't work so i went crazy thinking what is broken. I put our cpu back to where it belongs and very unfortunately we have noe the same problem. His pc wont show display. For anyone there that might have an idea can yiu please tell me if my motherboard killed our cpu.

Sure Sounds like it!

sounds like a defective cpu yeah. return the cpu if you can and try to buy another one, (maybe a 3400G or 3200G, but those are fluctuating in price unfortunately, you can try opting for pro 4000g on ebay or aliexpress if you are willing to game on an apu)

maybe buy another motheboard too if it's dead

Sounds like the motherboard did damage them, could be a VRM or power issue that fried the CPUs. That or you installed/removed the CPUs incorrectly and bent or broke pins.

It absolutely can. It happens relatively rarely but if something dies in power delivery in an unfortunate way you can have "fun" things like 12v going directly to CPU or something.

Do not plug any more cpu-s into this board...
