+ <p>Explain how the System Monitor can be used to find
+ misbehaving/resource-hogging processes. (A lot of process use 100% CPU or
+ similar if they hang, for example.)</p>
+ </comment>
+
+ <p>A program that is using more than its share of the CPU may slow down the
+ whole computer. To find which process could be doing this:</p>
+
+ <steps>
+ <item>
+ <p>Click the <gui>Processes</gui> tab.</p>
+ </item>
+ <item>
+ <p>Click the <gui>% CPU</gui> column header to sort the processes
+ according to CPU use.</p>
+ <note>
+ <p>The arrow in the column header shows the sort direction; click again
+ to reverse it. The arrow should point up.</p>
+ </note>
+ </item>
+ </steps>
+
+ <p>The processes at the top of the list are using the highest percentage CPU.
+ Once you identify which one might be using more resources than it should, you
+ can decide whether to close the program itself, or close other programs to
+ try to reduce the CPU load.</p>
