How do I check what programs are using the most resources?

So your computer is running slow and your not sure why?  A good place to start is see which applications are using the resources in your computer (CPU or Central Processing Unit / RAM or Random Access Memory).  To do this follow the steps below:

1. Press all three buttons together (“ctrl” + “alt” + “del“) or right click on the start bar on the bottom of the screen and select ” Start Task Manager“.  For Windows 7 or Vista, after pressing “Ctrl” + “Alt” + “Del” you will have to select “Start Task Manager“.

2.  Now you will see the “Task Manager” screen.

3. Click on the tab that says “Processes“.  You will see many columns and the two that are most important for this purpose are “CPU” and “MEMORY“.  (see image below)

4. If you click on either of the tabs (RAM, CPU) it will sort lowest to highest and vice versa.  Order from highest to lowest and see which programs are requiring a lot of resources as their might be an issue with this program.

Note: “System Idle Process” is good, and under the CPU column, System Idle Process should be above 90%.  (That means that 90% is available for any tasks needed.  If it is much lower than that you have too many processes running.
