Every time I start up my computer, the last thing I get during bootup is a Windows error message: "RivaTuner 2.0 Final Release has encountered a problem and needs to close. We are sorry for this inconvience", with the old "Send Report" or "Dont Send" bit to MS.I have the 8800GTX about 15% overclocked, although I get this message either with factory defaults or overclocked settings.I simply close the window, my settings are retained both in RivaTuner and in the NVIDIA settings and I see nothing wrong anywhere. Everything seems to work and display fine with no effect on anything I can determine.Has anyone else seen this message and/or have any comment concerning its cause?Thanks:RTHASUS P4-E-SLI MotherboardE6600 Core 2 Duo CPU8800GTX Primary Video CardS3 Savage4 S3 Graphics Inc.
