It's now over a week since I placed the post above and over 100 views have been registered. In spite of this there has been no reply. I'm not sure what to conclude by this. Is the Strix Z390 considered to be too old to be of any general interest? Or is the problem I'm having considered to be just too trivial to warrant a reply?
With my limited knowledge of this class of computer I am concluding that the problem is likely to be a failed MOB or CPU. A simple substitution with a new MOB or CPU may well resolve the problem, however I am reluctant to go to the relatively high gamble and expense involved without some reassurance that there are no other obvious less costly checks to make first.

Many thanks ahfoo and apologies for not being clearer. The only Ram that I have is two sticks of 32 GB making a kit total of 64 GB.
Stick A = 19515803593
Stick B = 19515803594
This kit is not on the Asus QVL list, but the MOB is on the G.Skill QVL list for my kit.
If I put Stick B in Slot 2 (DIMM-B2) the computer boots normally to Windows.
If I put Stick A in Slot 2 (DIMM-B2) the computer boots normally to Windows.
If I then leave Stick A in Slot 2 and put Stick B in Slot 4 (DIMM-A2) the computer fails to boot.
If I then remove Stick A and let Stick B remain in Slot 4 the computer fails to boot.
If I then move Stick B to Slot 3 (DIMM-A1) the computer fails to boot.
The system will not go past the orange LED for DRAM POST in the Q-LED array when it fails to boot. I have reset the BIOS to default state between each test, so no OC or XMP.

For Asus motherboard running different ram topology. Hence In pair you need to insert only Slot 2 and 4. No other option.

I did mention in my first post that this ram kit did work fine in dual channel mode for 2.5 years in the MOB.
