I'm a computer tech and did my IT degree here in Oxford, UK. I've worked as a computer tech since finishing Uni.

I recently swapped a load of hardware and was having the same kinda issue. In the end, I realised that the CPU temps were way too high and that the PSU I had in the "new: case was far too weak for my system.

From what I am getting from your setup is that you fixed one issue, but it does sound like you've not go good enough airflow around your system and FF14 is causing it to overheat and shutdown. Most people have already pointed out the key issues and their advice is pretty sound. Could parts be on their way out? It's possible, as FF14 stresses out systems like very few games I know (It killed my original PS4!)

I will be honest and say I don't like AMD stuff that much, as they just seem to fail to get the job done as easily as an Intel/Nvidia setup. Most games tend to work better with this combo, as it's been an industry standard until the last few years and now the high end AMD CPU's are beastly. I got myself some quality secondhand parts and built myself a rig that allowed me to use the better parts of my previous system.


Personally, I would ditch Windows 8 ASAP, as it's bloody horrid. Windows 10 makes life much easier and the difference between 8 to 10 is just like Vista to 7. The more modern OS and drivers would help, as they may allow your system to run more effectively.
