I acquired the PC second-hand and had to install some components; it functions well in and out of games, though strange noises are coming from it. It almost sounds like a spinning hard drive with scratches. Once it began making that noise, I disassembled the PSU and discovered a lot of white paste on it, which feels like rubber. I’m hesitant to make a video but am worried about reassembling it later. Will upload a picture?
You might be hearing coilwhine but it's completely normal and safe. This power supply appears very dirty though! Yikes. Avoid touching anything inside unless you're certain, as mishandling could cause serious harm or even death—even if the device is unplugged. It can retain significant voltage for some time after being removed from power. The white material is likely adhesive, epoxy, or silicone used to insulate or separate parts during transport.
Thanks for your message. I noticed a lot of white glue residue. It seems to be from the PSU's and likely not the previous owner's work.
