Ho Ho. Or possibly ho hum. So the new PSU went in like a charm. It's a nice quiet Gigabyte jobby, fully modular (although tbh I've never quite seen the point of having the mainboard supply cable as modular, unless you intend to have two PSUs for a load of devices, with only one mobo). 

Of course, because it was so straightforward, I had to have a poke about in things like device manager and event viewer and suchlike. 

Spotted that there'd been about half a dozen BIOS updates since mine, including some major security bits and bobs. So I stuck a new BIOS in. That worked like a dream too. 

Then I checked my email and found out that my copy of MS Office 2019 had been deactivated by the BIOS update. As the thread title expresses it, "POO!" That nice man in Slough who sold me my copy doesn't seem to be around anymore, so I'm seriously contemplating becoming legit and subscribing to Office 365. I suppose I could go Open Sauce with Libre Office.

I use both and prefer libre except sometimes it messes up the formatting of Word docs if there is some kind of elaborate layout with pictures. Other than that it transparently opens and writes valid .docx etc formats. The Excel clone is pretty usable for an amateur like me.

I've used Libre Office (and Open Office before that) for years, on and off. I briefly used it for my main office suite. Interesting differences, and mainly down to personal preference I suppose, but I always liked MS Office best. I can see why things might be the other way. It wouldn't break my heart if I was "stuck with" Libre Office.

Mind you, when I started work we had a typewriter for everyday letters, and most memos were written with a pen. 

I like LO because it's free, and also because I hate Microsoft and the horse the it rode in on.
