PSU fan started making a really horrible noise
> that I find difficult to describe. >

Good morning,

Many PC have auto shut down built into the CMOS if the system get too hot.
The noise you hear from the the PSU is most likely the bearings or sleve
going out in the PSU fan. If you are a builder you can replace the fan. You
may have to snip & solder the new fan wires in if the PSU fan is hardwired
to the the unit. You could also replace the PSU. I dont know what MHZ you
system is but you may want to look at a small CPU cooler for the processor.
