  3. CPU constantly at 100% in task manager

    That is exactly what I did previously. I tried setting max to 80% to test and task managers cpu displays constant 80% instead of 100% on the performance tab and 80% above the cpu column in the users tab. Sadly it has no effect but thank you for the suggestion.
