Hi,

Machine is a Dell Inspiron 530 desktop, circa 2012, running VistaHP x86,
belonging to my 93 year-old mother-in-law. She called me to day and said
"It's broken".

The power button does nothing. When I hold in the power button, there's no
sound whatsoever. The fan in the back of the power supply does not spin,
but the little green light on the back of the power supply does glow green,
When unplugged, the light goes out. Other than that, nothing makes a
sound, and nothing else occurs.

Here's the power supply:

Sound like a PS issue?

I doubt if it's a PS failure, if there's a green light on the back. It
could be a single faulty component which is preventing a power up, or it
could be a faulty motherboard.

If you have the time, I would recommend you try removing one component
at a time from the PC and then try powering on. E.g. unplug the CD-ROM's
power and data cables, see if it powers up. If it doesn't, replace the
cables and remove the hard disk cables and see if it powers up then.
Just remove one thing at a time and if it still doesn't power up after
you tried removing each one in turn, then remove everything from the PC,
all components, PCI cards, until there's just the power connector and
the front panel switch plugged into the motherboard. If there's still
nothing then, you probably need a new motherboard. You could get one
from eBay.
