Initially replaced the 980Ti was using (it had a fan malfunction the previous year, repaired under warranty) thinking it was the Gcard failing again, but continued having the problem.
The PSU I was using was pretty old, but it was a 1250w, so I had more than enough wattage. The problem was simply that due to age and general breakdown, the PSU was fluctuating its supply to the PC.

So my recommendation is to try a new PSU.
Also, its possible to still do the free Windows10 upgrade if you can find the relevant links. Which I would recommend, since previous versions of Windows have had their support dumped by a lot of places.
This GPU of her drains power from the PCie slot and it could be motherboard that is not able to sustain her GPU power drain. PCie power section with FFXIV launched could get hot and mess up the currents and voltages that is going to the graphic card, it may eventually break the graphic card by doing so.
So i again recommend checking the game with a second graphic card, and consider changing Mobo + CPU all together because its pretty old.
