Explanations
The PC air intakes are probably clogged with cement dust. This will stop fresh, cool air from entering the PC and cause the CPU to overheat. That’s why the system won’t reboot immediately because the CPU needs some time to cool down. You should install a filter in front of the PC air intake and instruct the customer to clean the filter often. While you are working on the computer, you should clean out the inside of the system and vacuum out the exhaust of the power supply (without opening the power supply of course). If the PC had a virus, that might cause it to lock up or shut down, but you would be able to reboot the computer right away. Plus, there would probably be other indicators of a virus. The CPU heat sink could be an issue and could cause the same results, but it is less likely. Companies often buy computers from popular manufacturers such as Dell and HP; these computer manufacturers spend a lot of time designing their heat sink/fan combinations to work with the CPU. If the power supply was underrated, it would cause intermittent shutdowns, but not lockups. Nothing in the scenario would lead you to believe that the computer uses so many powerful components as to make the power supply underrated.

Explanations: What should have been port 143 was probably configured incorrectly if the person can send but not receive e-mail. The Internet Message Access Protocol (IMAP) receives e-mail and uses port 143. The Simple Mail Transfer Protocol (SMTP) uses port 25 by default to send mail but will use port 443 if SSL or TLS security is implemented. Port 110 is the POP3 e-mail port. POP3 also is used to receive e-mail, but not in this question’s scenario. By the way, another port that is used for SMTP is 587. This is done to avoid being blocked by ISPs and to reduce spam. Mobile devices such as Android phones can be a little more difficult to configure e-mail on, as compared to PCs. Be sure to work with mobile devices and go through the steps of setting up e-mail on both Android and iOS.

Explanations: Internet Explorer (or any other web browser) is normally used to configure a router. It’s sometimes referred to as romming into the router because the configuration program is stored in the ROM chip of the router. You can type the IP address of the router into the Windows Explorer address bar, but that will simply open an IE (or other browser) tab. The Device Manager is where you enable and disable devices and install, update, and roll back drivers for devices. Msconfig is used to modify how the computer boots and to enable/disable programs and services.
