A user complains to you that her system hangs for no known reason. After asking her a few questions, you do identify these symptoms:
The system hangs after about 15-20 minutes of operation.
When the system hangs, it doesn't matter what application is open or how many applications are open.
When the system hangs, it appears as though power is turned off: there are no lights, spinning drives or other evidence of power.
You suspect overheating might be the issue. To test your theory, you decide do to the following:
1. You want to verify that the user has not over clocked the system. How do you do that?
2. You decide to check for overheating by examining the temperature of the system immediately after the system hangs. Describe the steps you take to do this.
3. You decide that overheating is the issue. What can you do to fix the problem?
4. You fix the overheating issue and the system continues to hang. What are some possible problems that could still exist?
