I believe that my RAM isn't being utilized efficiently. I'm on XP SP2,
with a P4, have 512MB of ram, and a 20GB hard drive. Looking at the
task manager, my system is using the Paging File as soon as I start
up, before I open any applications. My guess is that Norton System
Works is consuming a lot of Ram, but 512MB?
I looked at my processes and they're consuming only 248MB. My
available memory is 222MB, cache is 236MB, but the paging file is
325MB! This explains why my hardrive is constantly rattling. Can
someone give me insight as to why my system is using virtual memory
when I have plenty of RAM available? I never had this problem with
Windows 2000 and Norton Installed.
You are mixing up *allocating* space in the page file with *using* space
there.
Windows preallocates virtual memory in anticipation of a possible need for
it, even though that allocated virtual memory may never be used. That
preallocation saves you time if it turns out that it needs to use it, but
costs you nothing if it doesn't use it.
For more information, read this article by the late MVP, Alex Nichol,
"Virtual Memory in Windows XP " at

Over and above that, you might want to consider getting rid of Norton System
Works. It's a pile of junk that does nothing useful for you, but can impact
performance negatively.
