I have found out about memory leaks now. I and going to try running one program at a time and see which one is causing it. Thanks for all your help.

Could you please explain what this means. Is it a bad application?

Thanks for that. It's a bit heavy but I think I have got the gist of it. By the way, before I set the PF sizes and rebooted last night, a message balloon popped up saying that the page file size was being increased by the system because I was running low on memory. I only had one application (Firefox) running at the time and it had become very slow. I find it difficult to understand what would be using up the memory.

I forgot to add that at the time of the task manager snapshot, there were no applications running.

My home PC has 1024MB of RAM and the PF size was set to System Managed Size so I have set the min and max values to 1536MB as you suggest and rebooted. It's gone back down to 312MB now. A snapshot of the Task Manager before I rebooted can be seen at http://www.fuchsiamagic.com/misc/pf.jpg where the PF size has increased to 2.13GB and the CPU is busy doing something. It dropped back to normal util shortly after this.

I use MS Office 2003 at work, but not at home where I use Firefox and Thunderbird. At home I also use Norton IS 2008. No Findfast as far as I am aware.

One gig at home and 512megs at work. As I said in my original post, I don't see any services or processes running which should not be, or any excessive CPU utilization.

Can someone please answer the question as to why the page file on both my home and work computers gradually increases in size to the point where everything slows right down. It usually starts at about 300megs where everything is fine and slowly increases to about 900megs after about a week. Shutting down all applications only reduces it to about 600megs. Why doesn't it go back down to 300megs where it started? Only a reboot will do this. I don't see any processes running which should not be. I have tried altering the PF size, but it makes no difference.
