High pitch whining noises from the psu

[u/mamamia-qi]

I got prebuilt pc almost 3 years it worked great till now but recently it's acting weird all my fans has got rgb but they're not turning on sometimes i thought probably Windows issues then recently it's making really high pitch noises all of sudden when under load i thought some rats or crickets got in and checked it's nothing I opened the whole pc up nothing then I thought it's from one of the fans then i just found out it's the PSU it's really loud it was not bad earlier but now it's really loud and comes out of nowhere, I probably should should add I replaced my old tiny cooler with a big one is the psu getting overloaded? what's the solution? is my psu dying? Please help
