c. Wait about 30 minutes for the system to cool down and try again

Explanation:

When troubleshooting it is important to eliminate all possible faults one at a time. In this scenario, the first problem could be an overheating CPU. To eliminate overheating the first step would be to let the system cool down for some time then restart the computer. If the computer turns on and then hangs again after 15 minutes, the next step would be to install an additional fan and then monitor its performance. If the problem is eliminated, it means there was a problem with the cooling system of the computer. However, if the problem persists, it could be a problem with the power supply which might need replacing.
