I open these applications in my desktop computer:

  • Visual Studio 2010 Professional
  • IBM Lotus Notes
  • Google Chrome

And when it is idle for an hour and I restore the windows, the user interface responds very slowly. My computer auto-lock itself after being idle for 5 minutes. I also minimize the applications using a docklet (RocketDock).

Why is it slowing down and how can I prevent it from slowing?

My OS is Windows XP Professional SP3, Pentum(R) Dual Core @ 2.80 GHz, 1.99 GB of RAM.

Please help. Thanks in advance.

Please check your RAM usage, as windows is probably paging (Copying to disk) these memory intensive programs that are idle.

see this post: How to reduce disk thrashing (paging)?

As well, in WinXP, default behaviour is to always keep physical memory as empty as possible. Hence why disabling paging resolves this issue on XP, but doesn't really do much on Vista/7. – EKW Mar 8 '12 at 7:08
@EKW Should I disable my paging? How can I disable it? Please help. – John Isaiah Carmona Mar 8 '12 at 9:03
@JohnIsaiahCarmona With 2gb of RAM, I would definitely not recommend disabling paging. GKoe's answer is a good one - check your memory usage in Task Manager, and upgrade it if your maximum Commit size is greater than your physical memory. – EKW Mar 8 '12 at 15:29
@EKW Thanks. I'll try it. – John Isaiah Carmona Mar 9 '12 at 1:10
