The new PS arrived. It's not that. ;-)

Stripped the thing down and cleaned everything. The Asus board I have is
known to have a problem with the chipset cooling, so removed that and
cleaned and applied new paste. Battery was at about 2v so replaced that
too.

It fired up and selected the BOIS page. But on configuring, saving and
exit, back to not firing up at all.

So looks like an MB failure?

Particularly if any of the caps look bad. Still very unusual that the
PS fan only runs while the reset switch is held in tho. Does the new
PS still do that ? If it doesn’t, likely just an usual original PS and
a separate fault with that.

I'd just buy a new motherboard, but this machine is configured for my
needs including a Serial port and not sure many new ones have this?

Plenty still do. It's laptops that mostly don’t anymore and you can still
get serial cards.
