If the capacitor fails completely then the computer will most likely not power up at all.

Power supply electrical buzzing sound is it a problem intelligent power capacitor. Easier then removing the Motherboard and PSU to further narrow it down. In addition to pass stricter new regulatory standards EMI generated by power supplies must be kept lower than ever before. The problem is that most of the energy stored in the capacitor is not being used.

The noise problem is due to the fact that linear power supplies have large transformers and other magnetic components that operate at the AC line frequency 50 Hz to 60 Hz. This can be caused by devices that introduce an electric potential to the ground connection. However the same noise can occur under a load with a poorly designed or defective power supply as the coils may vibrate under electrical stress at a sub-harmonic frequency.

I am trying to remove noise from a 33V supply. Here I wired it as an astable multi vibrator. After wiring up the circuit connect it to a power-supply.

I have tried putting various capacitors across the output but hasnt made any difference. If the noise problem lies in a snubber capacitor consider replacing it with a metal-film type or increasing the value of the resistor in series to reduce dVdt seen across the capacitor. Selecting capacitors with lower ESR and ESL will lower noise but be careful some power-supply circuits use the ESR to provide the error signal for feedback.

The 2nd part of the problem is that a guitar is an unbalanced signal so any common-mode pick-up hum from the SMPS will asymmetrically couple to the input and its local 0 volt signal return and the result is that this hum. DO NOT touch the capacitor terminals or you may get shocked. The glue helps reduce the vibration and noise the coils generate during normal operation.

We have an input capacitor 47uf an output capacitor 47uf and an inductor 1uH. So it may be worth changing the cap. The buzzing could also be a sign of damage or just a resonance by coincidence.
