Subject: 5 Short beep on start up

Good morning,

For the last couple of months I have been getting occassionally 5 short beeps when starting the PC, after that the system seems to restart and then it all works correctly. Other times it boots normally with no beeps nor problems.

My specs are: B450M Steel Legend
              Ryzen 5 3600
              GeForce GTX 1660 Super
              Ram 2x8gb 3000mHz Corsair Vengeance

I was worried at the beginning but since it all worked perfectly even after the beeps I didn't give it much attention until now. I don't know the reason for these occassional beeps, I would be very grateful should anyone help me out.

Thank you in advanced.

5 beeps is either CPU or GPU. Maybe reseat the GPU, and CPU as well.

Ok, but I don't understand why it only beeps sometimes and why it still works after it beeps

There might be loose connection, thus me suggesting to reseat both CPU and GPU :)

What is your PSU? If the beeps only happen on a cold boot (after the system has
been switched off for a prolonged period) then it could be dying. I have seen it
before where the PSU produces lower than normal voltage when not warmed up, this
can cause POST failures, GPUs not initializing and all manner of other gremlins.

Once warmed up (which takes longer the more the unit degrades) the system functions
as normal.

It is a corsair cv550.

If I'm not mistaken it happens at random times, sometimes on a cold boot and others maybe 30 minutes after I have shut it down.

It boots normally more times than it does by beeping.

I have reseated the GPU and during the first boot it has not beeped. I will let you know if it beeps again.

This morning it beeped again although yesterday it did not beep neither of the three boots I did.

If you have multiple PCIe power cables on your PSU try switching the one/s connected
to your GPU, just one if your GPU has 2. This should spread the load differently
and could help. If that does not help swap the PSU for another one if you have one
or see if you can borrow one to test with.

I have now done that, I will let you know

Good luck

During the first day it did not beep, but now it has beeped already two times in all.

What else could I do?

Swapping for another PSU.
In BIOS there should be a section telling you all the main voltage outputs. Would be interesting to see the values

This is all I could find about the voltages in the BIOS, not sure if the GPU is one of them:

Using MSI Afterburner I have seen that on idle the voltage for the GPU is 625mV and while playing a game 1050mV

That is normal.

Hm, your 12V rail has ripple of 196mV, which is too high,
and 3.3V has 76mV ripple which again is a bit too high.

However I am not Electrical Engineer, and PSU specs are a bit muddy, since some say that PSUs tend to "ripple" out of specs when not loaded.
You could download HWInfo app, start it, scroll to all the voltages, then load your system with a benchmark or something, and observe how voltages are behaving.
Basically 12V rail's maximum ripple can be 120mV plus or minus, so if you see 12.120V, that is still within specs, same with 11.880V. Yours is 12.196V
3.3V rail I believe has 50mV spec allowance. So if you see 3.350V, that is still acceptable. Yours is 3.376V
