What can I do with the whole PC lagging a few times?

So my PC has the following symptoms that the whole system has lagged a few times. And so that the screen jerks for a few milliseconds, at the same time the sound from the sound card jerks for a few milliseconds. And the blatant thing is, it didn't even help a fresh Windows 10 reinstallation. The symptoms with a few laggs still occur, and that's annoying, especially when listening to music. And no, that has nothing to do with the sound card, with other external sound cards the same symptoms occur.

Because I hadn't even had this strange sound lag on my old laptop, which is much weaker than my PC.

Does anyone know what it is? Is it because of the mainboard that it sometimes stalls? Is it due to the power supply that it does not have enough wattage and is therefore spinning around?

I think it's the hard drive, but I don't know

Can't be either. Because even when I had 1TB HDD at that time, these same symptoms also occur.

And now that I have a 500GB SSD and have removed the old 1TB HDD. Windows 10 freshly reinstalled = The symptoms are still there.

So do you have the problem with both hard drives? Then maybe the mainboard. You can also take out a ram strip if you have two. Maybe one of the modules is causing the problem.
You could still test that

Mainboard is hard to try if you don't have another one lying around.
I don't think power supplies.
