Rail disable the "Logitech G Suite (whatever it's called) for my G19KB LCD" and try to see if it occurs again.I think you already did but run "whocrashed" and see if it is always the nv driver.Just one final note for whatever it is worth just because a card came factory oced doesn't mean it is fully stable though, I will try adding a bit more voltage as the last resort.
Yeah, I'm 100% sure it was all related to a software hiccup some where.
Been using the GTX 680 since yesterday, not a single issue and her the GTX 780 with no complaints (only praise she can now max out some of her games).
I ended up not being able to swap the coolers today (possibly day off). Been watching my PSU with Corsair iLink. Odd that the fan never seems to come on. Guess I don't use as much power as I thought. Haha.
Thanks for the heads up the program. Event Viewer has been useless with no extra info to see if there was a possible conflict any where. Wonder if I can use whocrashed it retroactively and see if it can find info from Eventviewer I couldn't see.
