Increase your RAM and so system speed
        1). Start any application, say Word. Open some large documents.
       
      2). Press CTRL+SHIFT+ESC to open Windows Task Manager and click Processes
      tab and sort the list in descending order on Mem Usage. You will notice
      that WINWORD.EXE will be somewhere at the top, using multiple MBs of
      memory.
         3). Now switch to Word and simply minimize it. (Don't use the Minimize
      All Windows option of the task bar).
       
      4). Now go back to the Windows Task Manager and see where WINWORD.EXE is
      listed. Most probably you will not find it at the top. You will typically
      have to scroll to the bottom of the list to find Word. Now check out the
      amount of RAM it is using. Surprised? The memory utilization has reduced
      by a huge amount.
         5). Minimize each application that you are currently not working on by
      clicking on the Minimize button & you can increase the amount of available
      RAM by a substantial margin. Depending upon the number and type of
      applications you use together, the difference can be as much as 50 percent
      of extra RAM.
       
      In any multitasking system, minimizing an application means that it won't
      be utilized by the user right now. Therefore, the OS automatically makes
      the application use virtual memory & keeps bare minimum amounts of the
      code in physical RAM.
