Does your PSU or motherboard make a crackling sound?
It's been about four months since this problem began. I'm not sure if it's the PSU or the motherboard, but the sound comes from the top of the tower. The PSU is two years old, Silverstone St50F, and I haven't used even half of it. The motherboard seems to be failing—maybe it won't open after shutting it down, and you have to wait about 30 minutes before trying again. I've checked RAM, CPU, and PSU in another PC, everything works fine, so I think the issue is with the motherboard. Is the crackling noise typical for a PSU or motherboard? And after the noise, my monitor would black out and then come back on.
It’s a bit of plastic that bends quickly—only for a short time. I don’t have case fans, so it isn’t affected by them. Once the noise stops, my screen turns black for a moment before returning to normal.
It's not necessary for a case fan; your CPU cooler also relies on its own fan.
