[strike]With 125C you CPU should melt 😀
Did you applied thermalpaste ? Are u using PC or laptop ? Whats your system specification ?[/strike]

Ok i guess we are talking about fahrenheit yes ? Reapply thermalpaste, check if your fan is working correctly. Give full system specification along with CPU fan

I just used the thermal paste which comes applied. This is a pc I just built. Specs are 500w psu, asrock mini itx AM4 AB350 mobo, ryzen 2400G with stock cooler

Stock AMD thermalpaste/fan are crap but it shouldnt give you such high temps. Is your case well ventilated ? You are giving us a socket temperature or a core temperature ? Upload HWMonitor screenshot.

 

[camrd33]

I don’t remember whether it was core or socket sorry. And I can’t check because I can’t get a post on the screen. I remember the the case temperature was 35 degrees so I think it is well ventilated.

Oh sorry, didnt noticed that xP
Do you have BIOS speaker ? Any lights on your motherboard are flashing ? (Some motherboards have CPU_fail leds etc.)

When powering on I get a short abrupt beep after running for a while and it turns off and tries to boot again

Try starting with one RAM stick. If you have a possibilty try to run your setup with a different motherboard.

 

[camrd33]

I only have one stick of ram and I do not have another mobo available. Do you think it’s the thermal paste or cOiler?

cooler*

If your PC is turning on and not going through POST then its either a faulty CPU or motherboard.

All fans spin including coy fan so I would guess cpu?

Easiest way to check it out would be to try setting your rig with different motherboard/CPU.
Spinning fan doesn't define working motherboard.
