My housemate's desktop has a noisy power supply

[MIPS]

My mom's laptop AC adapter was horrible at murdering FM reception until a noise filtering power strip and two chokes were added the the AC cord.
I find a lot of the cheaper power supplies omit AC line filtering components to cut costs. I got a small pile of junk reference design 300-500W ATX power supplies from the 2000's that are all like that.

If it's any consolation, it's just as bad in UK and Europe. The CE mark is compulsory on all electronic equipment and much else. It is meant to mean that the equipment is compliant with all applicable standards for safety, EMC etc. Rather like the FCC and UL marks in the USA. In practice the CE mark is widely abused and perjoratively referred to as meaning "China Export".

Given the house wiring problems described in another thread, I must ask if the computer is properly grounded?

The original poster stated that there was a lot of bogus wiring practices. Chances are the power strip, if used, is plugged into a receptacle that was not effectively grounded.
