I got this noise https://www.youtube.com/watch?v=y-4RllphqLo coming from my psu (http://www.ldlc.com/fiche/PB00105015.html ldlc bg500). The noise come irreguraly, sometime it stop for few hours and then it come back. Could it be harmful for my computer and can I fix it myself ?

How old is your PSU, have you cleaned it recently?

I bought it 2 years ago and the fan is clean..

It's probably just sparks going off inside the thing. It should be all right. It's pretty normal for bronze rated PSUs.
Ok ty, just, sometime the sound is really loud so I wanted to be sure
>>55552691
It probably has a switch style voltage regulator, its a way for them to increase efficiency by constantly turning on and off the power. It's literally the sound of a switch flipping on and off. It probably only happens when the psu gets warm or is under load, and otherwise functions without the switch regulator. I forgot the actual term for the component. It's perfectly normal.

Can also be this, is it more of a loud tick / click or kind of an erratic crackling sound?
>>55552691
Throw it away. I heard clicking on my old psu often too. I thought it wasn't a big deal since it wasn't rebooting on it's own or shutting down. Eventually it just shut down on it's own. I managed to do a backup of my drive before it killed it too.

Your fan maybe running out of oil. Open your psu carefully and apply sewing machine oil in the fan.
