PC cracking after waking up from sleep

The problem is actually in the topic, the PC works silently, but if it falls asleep and exits this mode, it starts to make a slight crackle, like the crackling of chokes. The sound is amplified with some actions, such as scrolling pages in the browser - for each turn of the wheel, the sound is stronger. After a reboot everything is back to normal. In principle, everything is solved by turning off the sleep mode, but the problem is strange and I would like to find a solution. Help if you have any ideas)
PS I found a couple of tips on the Internet, nothing helps - 1) turn on the power saving mode in the power supply,
2) turn off a couple of moments in the BIOS in the CPU configuration. 3) Turn on turn off hibernation
At the time of exit from sleep, consumption increases. So, it is cracking in nutrition, the question is where exactly. I would assemble the computer without a case, just on the table and localize the place where it cracks. If this is a capacitor, then it will soon hit the headstock, a popular sign. If the throttle is on the ring, then you can drop one drop of any quick-drying varnish on it, it should shut up. Just in case, it would be good to get an oscilloscope and poke on the power lines, if there is not a straight line, then you have already hit the grandmas, but you don’t know about it yet ... the right of surprise, yeah. And it happens that speakers crackle - from the power wires of the PC there is a tip on the ULF, the Chinese save on shielded wires, in this case the sound from the "motorcycle" to something similar to an old modem and it disappears if you move the speaker or its power wire.
Also fan resonance is possible. I wouldn’t have believed it myself if I hadn’t observed it with my own eyes and ears, bless you.
