I have a XP Prof machine on a Windows 2003 network and it has become unstable.
I notice that it starts off with a huge PF Usage (1.5 - 2 Ghz) although the CPU usage is around 2-3%. I have no applications except task manager running on the machine.
The machine has 512 MB memory and about 20 GB memory free.
I have attached snapshots from task manager. Can you please take a look at it and give me some ideas on how to optimize the memory and resolve this problem.
