Hey Jezra you nailed it. I turned off the HW Acc. and everything is working fine. I started a 480p video with system monitor running and it showed 95 to 100 percent usage on all four CPUs. With the acceleration off inside Firefox it showed 60 to 70 percent CPU usage on numbers one and three and twenty to thirty percent on two and four. RAM usage was the same so it was using up the CPUs it is a Hyper-threaded Dual Core that runs as a Quad.
