Well I went ahead an bought a new psu as a last ditch effort before returning the graphics adapter and it appears to have worked.
Minimum requirement is 450w for the card and my old psu was 460w so I was really not expecting that to be the issue. Especially considering that my old card was min. req. 450w as well and it hadn’t ever given me any issues.
The reason(s) I bought a new card was because Conan Exiles, ARK, and ESO would all get my old card’s fan sounding like it was going fast enough for my tower to lift off and take flight (read: REALLY LOUD). Not from any sort of errors occurring.
I figure that my old psu was just getting, well, old.
So I replaced my old 460w with a 650w and for the last two days there hasn’t been a single sudden system reboot. (fingers crossed)
I guess the additional animations for human combat over creature combat was just pushing my old psu over the brink. (also the old card has one fan compared to the three on the new one).
We’ll see. Two days of no issues is great but I won’t be convinced until it survives at least five days of heavy usage with no hiccups.
