So i bought a geforce 2080 TI Matrix card.

When i play Overwatch, 2xWow and archeage on the same time (They are open) and use many chrome Tabs, my PC is running fine.

But when i start FFXIV and just idle in town, then after some minuts my PC just restarts. (playing onn everything maxed out)

I even tried Benchmark software, stress test nothing crashes the pc besides FFXIV

anyone tried this before?
