I don't believe this is a hardware issue, as it started with the 384's like for many others. As for the PSU, I've tested and measured with a multimeter (and HWMonitor) before, and there were no signs of instability/fluctuations. FF crashes are rare, I've only had about 3 or so over the course of a few months, and since Mozilla improved recovery logic they really just manifest as a momentary black flash before the webpage is restored. Phase Shift is by far the most prone to crashing (again, not before 384), and GTA is a completely new development that - so far - has only happened once. Thank you for trying to help though, I appreciate it. Is anyone else having similar issues? Edit: I just now used Wagnard's tool to adjust the TdrDelay from 2 to 4 seconds, will see if that changes anything (though I know it's really just a bandaid rather than a real fix). Edit 2: TdrDelay made no difference.
