Currently my GPU, 8800 GTS 640 is not overclocked. I have started to notice white flashes in certain situations. For example, starting up at a country airport in Alaska and use the hat switch to look around it spot view - get some quick white flashes. This did not happen before. Happens with the 174.74 and the 180.4x driver also.
99% of the time all is well and this is more of a "what's happening" rather than an "OMIGOD".
Assuming the vid card is not going bad - would some anomaly in the system overclock affect the GPU?
Just as an aside, I know how to cause my system to reboot -
fly the SectionF8 F-86 FSX port over the Los Angeles Basin at 1500 feet 550kts doing a series of aileron rolls while using TrackIR to try and follow the horizon.
No blurries, no pauses - just a click - reboot. Of course, since I don't fly that way regularly it's not a problem - just an interesting aside.
Like the old story:
ME: Doctor, it hurts when I do this.
Doctor: Then don't do that.
