Alright, I'm back. I don't think it's flash at all, that seems silly as I always have background applications such as youtube running in the background, even before the problem.
The problem is that my Graphics card isn't using all of it's resources. I tried to get a better picture with MSI but it just appears with these values almost constant: (even while in games)
Temp: 33 degrees C
GPU usage: 0%
Fan Speed: 20%
Fan tachometer: 965 RPM / 10,000 RPM
Memory Clock: 150 MHz (the card comes with 1050 MHz)
Memory Usage: 0 MB (the card comes with 1064 MB)
Framerate: 0 FPS
So, from this data it would appear as though my card isn't even being used. I think my brother might've caused a sublight system to override the graphics, such as Intel HD Graphics.
QUESTIONS: Does Catalyst conflict with Intel HD Graphics? Could motherboard graphics be taking over?
