The problem started like 6 months ago, and its my psu making weird/annoying sounds and i dont know if its the psu or the psu fan. Its broken or something I have been told to stop using it but since i take class right now i cant take it out of my pc so any quickly solution i can do about it? I do flightsimming and my pc its on for about 5-15 hours in high load so in the future im planning to buy a new one but for now what its the problem with the psu?
The problem happens when im playing P3D (flightsim), Warzone ,MSFS2020 in the menu and when my pc is on high load.
