A couple of days ago I turned my old Athlon 64 machine on and soon after power-on I heard a loud clicking noise.
It sounded very much like something knocking against fan blades, so I disconnected the case fan, put my finger on the CPU fan and a pencil in the PSU fan.
No, the noise still happened.
It seemed to be coming from the PSU itself. The PC was running 'perfectly' but as the PSU seemed to be the problem I immediately turned it off.
I disconnected the PSU and powered it up with a jumper. It still made the clicking just not as much and maybe quieter.
I found the higher the load, the faster and louder the clicking.
Seems very odd that the PSU still runs while making such an 'bad' noise!
I searched the forum and found a similar problem posted here: https://www.badcaps.net/forum/showthread.php?p=250827
I also got this response:
But I want to start a separate thread here to avoid confusion.
So, where is the PFC circuit and what kind of diode am I looking for?
