If you’re having trouble with a program taking over your computer, slowing things down, or even locking things up, you can use the Reliability Data available in the Windows 7 Resource Monitor to see what’s happening inside the computer. The Resource Monitor knows all, sees all, and tells all (with graphs and statistics galore).
- Choose Start→All Programs→Accessories→System Tools→Resource Monitor.  - The Windows 7 Resource Monitor appears, in its Overview state. - To get there quickly, click Start, type resmon, and hit Enter. 
- To see which programs are hogging the CPU, click the Average CPU column heading. - That column presents a 60-second running average of CPU utilization. The hogs float to the top. - If a program has stopped responding, right-click it here and choose Analyze Process. You may be able to glean some worthwhile information that helps you whack the program upside the head. 
- Click the Memory tab to see how your computer’s memory is being used. - The bar graph at the bottom of the figure may surprise you. For example, if you have 4GB installed on a 32-bit Windows 7 system, a sizable chunk of memory isn’t accessible. - In general, if Windows reports many page faults (the graph marked Hard Faults/sec), you may be able to increase your computer’s performance significantly by increasing the amount of memory available. 
- When you’re done, click the X Close button to close the Resource Monitor.
