Why do my mobos burn a fuse?

Hello

Two cards have recently failed me. And I don't understand why it didn't happen to me before.
The only difference is that I moved home two months ago but I think it has nothing to do with it.
Before touching them I touch metal with my hands to get rid of the static. Here now I touch an aluminum staircase.
I have rubber soled shoes but I don't think it matters.
I leave the cards anywhere, but I've always done this.
What can it be?
Thank you very much and best regards

What cards? You mean your motherboard? What fuse? You got any photos of said issue? Could be a case short somewhere.

Sorry, I meant to say two motherboards. One is Asus and the other Acer. A photo will be no use: they look like new but they just do not function an ymore. I was just thinking it could be the power supply: at the moment I am using a Hama charger with a gadget that allows you to choose the right voltage. I bought it used not long ago and maybe that is the reason: maybe it is bad quality and I get shocks into the mobo.

What's the exact make and model of your power supply?

Hama 00012120. It's German made in China. But then, could it be the charger, when all it happens is that I do not get any video on display. The fan and the little light (leds) do work

That is a notebook charger?

Yes indeed

Nutella33 · 6 Apr 2020 at 14:23

I'm sorry, you are using a notebook charger to somehow power a normal PC?

No, buddy.
I have 4 defective moboes now. I have a rework station. The moboes are from notebooks and usually work but they do not show anything on screen. I am hoping I can get one good one out of the 4. The rework station I bought a few days ago and I have to get the hang of it. From now on, I shall be using latex gloves to be on the safe side and I exchanged the charger for a LITEON one.

Is the rework station to repair stuff, its hard to follow what and why?

Maybe the voltage selector is not reliable anymore.

This is pretty difficult to understand. Some pictures maybe?

Yes, but it might make more sense to help get the point across about what he is actually talking about...

I know that's why I'm laughing.

I dont know what kind of pictures you want. A picture of the board will be no use. I am sending this one:
