I have read all of the posts and my problem is similar and dissimilar at the same time. My computer is running slowly all of a sudden. My flight Sim's graphics are slow and jerky. When I went to Task Manager it shows that WAOL is over 311,000, the largest mem usage. In performance PF usage remain stable but, CPU usage is bizarre. As it scrolls, it jumps to 100 moves 4 bars and drops to 0 for one bar then jumps back to 100 for an additional 4 bars then drops to 0 again. It just repeats this with no veriation. I have never seen this before. Any and all advise or info will be greatly appreciated.
