Given that I've already observed different behavior from the system when the GPU isn't plugged in to power at all, would it still be worth pursuing this as an angle? > Most PSes only require 4 screws removed to get the cover off far > enough to inspect the usual cluster of candidate caps adjacent to > where most wires feeding out connect to the board. I'd probably have to disconnect and unmount the PSU to get it far enough out to remove any such thing, which would be doable but still a pain. It's also a modular unit, so rather than "wires feeding out" of the PSU itself there are connector ports, but I imagine that wouldn't make much difference once it was open. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
