Thanks Geo.
I purchased that Crucial, It took forever to arrive.
Bios wouldn’t recognise it but windows did.
Cloned the HDD and thought I was home and dry but I couldn’t make it my C drive.
Tried Hirens and all available utilities, eventually found a utility to change the drive letters.
Then it would’t boot to my new C drive.
Long story short reinstalled Windows by creating a bootable USB drive with Win 10 image from here.

And updated the drivers as above.
All seems fine so far, if there are any hiccups I’ll post here.
