|What do you mean by "caching physical memory" in quote?|
Is that a service or process in your task manager? I'm sorry, I do not have that listed in my task manager.
If you are trying to understand Vista's memory management system, you need to realize that it is very different from XP's memory management system ... assuming you know what XP memory management system is in the first place. Simply looking at the task manager or wherever it is you are getting your "caching physical memory" pop quiz from & drawing an incidence situation isn't going to cut it here.
We need to know the problem you are having with your PC.
