Cpu troubleshooting

[ozz.yyy]

So my new pc build is stuck in a bootloop and I've ruled out that the psu and ram are not faulty. The problem is in the motherboard or cpu. If the cpu was dead, would any fans spin up? I still get beep codes and the fans spin for 5 seconds before cutting out and restarting. If the cpu was dead would I get any sign of life? Many thanks for any replies

A few random Trouble shooting points i need to cover

 

Is the CPU power plugged in?

have you tried clearing CMOS/Bios settings?

have you tried with one stick of ram

have you tried with barebones hardware? (with just CPU and 1 stick of RAM)

 

and in general if the CPU was dead, then you would likely not get anything other than the post code (or beeps) stating there is no CPU connected

also in general, Motherboards do have much higher Dead on Arrival rates than CPU's

dont think so. certainly no beep or any sign of life except for power top fans amd stuff. 

on bootloop normally the mobo is the problem. if your lucky it just needs a new bios update but it could be more serous though. either way if you dont have a different cpu send it back.

I've tried all of those options

Ok, thank you  I think I will go to the local electronics store and see if the have a test bench I can try it on

How can I update the bios? It won't post so I have no internet connection

with a different cpu. sometimes older bios versions dont support newer cpu's. but if you dont have one send the mobo back. they will put a new one on it if there are no mechanical problems.
