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?

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?

Serial ports can be replaced with USB converters.

Yes and no. Although they work easily for most things, for some pieces
of equipment that you might want to connect to, it can take trying 2 or
3 different converters before you find one that works.

That is why I now go for a brand rather than cheapie no-name USB converters.

Megasquirt engine management systems are one example, while some PLCs
are another.

I don't know. There aren't many chipsets and so few drivers exist. I've
also made my own using an ARM processor and used the Windows native
"Usbser.sys" with success.
