applied the patch and still the same issue. 
You definitely have too many background tasks running on your CPU. For instance, quicktime, apple support, iphone handler, etc.
You can find out what background tasks are running by hitting ctrl-alt-delete on your computer, going to task manager and then looking at how many background tasks are running. I disabled some because initially, I was running 65 background tasks, which all run and reside in virtual memory.
