So recently it seems my videocard will turn itself to normal clocks (core: 835Mhz Memory: 2052Mhz) and get to ~80C degrees even though all I am doing is some video playback. According to GPU Shark its usage is around 97-99%. After turning the video off, the card won't revert to 'idle'. After a restart the clocks are back at its 'idle' settings, throttled down from 'max' (core:50Mhz Memory: 135Mhz). I am unsure what this is... I have scanned to pc for possible malware or virusses, but there is nothing present. This just started happening this morning as well. It was fine before. It is just completely baffling to me. edit: So I restarted my computer, and just browsing the internet all the while monitoring gpu activity. At the start it was fine, but after 10-15 minutes it went full bore at normal clocks and doesn't want to let up. edit2: I downloaded Palit's Thunder Master and fiddled around with the setting, at one point clicking the 'save bios to file' icon. Now that seems to have reset something on the card because it is now acting like it is supposed to. Will see if it lasts.
