So I've got RiveTuner set to start automatically with Windows Vista x64. Normally I get 2 blocked instances of RivaTuner by UAC and I just start them both (1 is RivaTuner itself, 1 is the monitoring portion). After startup I'm usually left with the RivaTuner icon and the Core Temp icon in my system tray. After my last two startups, however, I no longer have 2 instances starting up, merely 1. And the temperature reading no longer appears in my system tray. If I go into monitoring setup to look at my Core Temp monitoring setup the "Core Temperature" option with the checkmark no longer appears in the list. I use RivaTuner for custom fan speeds based on GPU core temp but now I seemingly can't. Anyone know what could be going on here? I really don't want to have to manually set my fan speeds before and after gaming. Why would the Core Temp monitoring option just vanish?
