Issues with CPU Upgrade

[wildtomatodwarf]

I have upgraded my cpu to the Ryzen 5800x and upgraded my bios, reseated my cpu, ram, put in a last gen Ryzen (which works). Is my new cpu defective or am I overlooking something. 
 

motherboard is the Asrock X570 Extreme 4

 

thank you for any help given.

Forgot to mention it turns off and on after a few seconds with new cpu

Check for bent CPU pins.

How long have you let it reboot cycle? 5, 10, 20 minutes?

I typically do not let it cycle on and off more than 2x as it doesn’t post or have a video output.

No bent cpu pins checked those when the cpu arrived and rechecked after I put in a last gen cpu.

You probably already tried resetting the CMOS?  Doesn't seem promising.  I would let it try for a few minutes like AaronThomas said.

I haven’t reset that since I would then have to put in am the old cpu I’m borrowing and redownload the bios update. 
 

Other than letting it turn itself on and off again any other ideas? Because I’m starting to think this is a defective cpu.

That's a tell-tale sign of a dead CPU when the system powers up for just a few seconds, resets, and tries again in an endless loop.  That's why I suggested checking the pins.  Sorry, that sucks..

Clearing the CMOS will not remove your updated BIOS. Once a BIOS has been flashed to a particular version, only flashing it with another version will alter it.

They're referring to this as their reason why they can't clear CMOS I think.

I believe OP mentioned that the system was booted with the old CPU?

He said it worked with a previous gen CPU didn't specify which exactly.

The original cpu I had was a 3600x and used a 3200 to update the bios.

I did reset the CMOS but it still just a loop of on and off. So I jus requested a replacement unit from Amazon (not the easiest thing to do) and hopefully it’ll work this time. 
 

thanks for all the information and help. 

[wildtomatodwarf]

Okay. I have just placed the replacement cpu in and still cycling on and off....idk what it could be.

My motherboard was the issue even after the bios was updated. But changed the motherboard and it all works great now!

 

thank you everyone for the tips and ideas.
