Ok. I checked the game forums for GW2 and Skyforge and nothing turned up. I Ran RealBench 2.4 and the Benchmark test ran fine for 1 run. I then switched to the Stress Test with all the tests checked, Duration: 1 hour, using full 32GB memory. Unfortunately, I then left the system and when I came back the pc had rebooted, and I found a BSOD minidump that apparently occured within a couple of minutes from when I started the stress test up.
The BSOD pointed to ntoskrnl.exe with an IRQL_NOT_LESS_OR_EQUAL debug code. I've gotten this same code associated with ntoskrnl.exe at least two other times when playing the games.
My next step is to start the Stress Test again, but stay and watch it and monitor CPU/GPU temperatures.
I haven't gotten a minidump analysis yet from the good people at tenforums.com yet, but I'm watching for it.
Chino, thanks for the suggestions. I'll try both of them: running other games and trying other synthetic benchmarks.
