Zoey has brought her computer in for servicing. When she dropped off her computer, she mentioned that her computer will sometimes spontaneously reboot and freezes occasionally. Which of the following is the MOST likely cause? (A) Bad network card (B) Overheated CPU (C) Failed UPS (D) Failing Drive

Option (B) Overheated CPU

Explanation:

The above problems mentioned are due to the problem with the CPU. Overheated CPU can result into freezing the computer and unexpected rebooting. CPU stands for Central Processing Unit and is responsible for all the instabilities in the hardware parts of the computer. So, option (b) is true. A Network Card is responsible for connecting the computer to the internet. It also has other names like Ethernet Card. A bad Network Card results in problems with the internet and network connections but not the above problems. So, option (A) is false. UPS is Uninterrupted Power Supply. It is an external power device to provide the power supply to the computers in case of emergencies to not shut down the computer instantaneously. The above problems are not likely to be the caused by the failed UPS. So, option (C) is false. Drive is a hardware device to store information. It can be removable drive (optical drives like CDs, DVDs) or non removable like (Hard Disk Drive). A failed drive results in problems with the storing information. The above problems are not associated with it. So, option (D) is also false.

Option B

Explanation:

There is a built in functionality in every OS (including windows and IOS) that reboots the system whenever the temperature of Processor reaches to a certain limit. This functionality is to save the hardware of computer so that nothing of it will burn by rebooting the PC which in this specific case will start the fans of computer to run with rather high speed to take out as much heat as possible.

Option A is rejected because Bad network card will result problem in using the network and will not reboot the system.

Option C will make the PC UPS to not to start the computer rather than rebooting it.

Option D will result in no windows start functionality rather than rebooting it.
