Performance problems 

For best performance with Windows 2000 or XP, your computer should have at least 96 
to 128 MB of memory (RAM). 

If the computer pauses or runs sluggishly 

•  This may be normal Windows behavior. Background processing can affect response 

time. 

•  Certain background operations (such as a virus-scanning program) can affect 

performance. 

•  Press CTRL+ALT+DEL to see if an application is not responding. 
•  Restart the computer: click Start, Shut Down (or Turn Off Computer), Restart. 
•  Some file browsers respond slowly while processing graphics or waiting for broken 

network connections to time out.
