An overheated CPU is the most likely cause of a computer that has been randomly shutting down without warning. A CPU generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the CPU or cause it to malfunction. A computer that shuts down randomly is a common symptom of an overheated CPU, as the system tries to protect itself from further damage by shutting down or restarting.

The other options are not as likely to cause this issue. A corrupted OS may cause the computer to crash, display errors, or fail to boot, but it does not affect the CPU temperature or the system fan. Incompatible memory modules may cause the computer to beep, display a blue screen, or fail to recognize the installed RAM, but they do not cause the CPU to overheat or the system to shut down randomly. Low system resources may cause the computer to slow down, freeze, or display a low memory warning, but they do not affect the CPU temperature or the system fan.

To troubleshoot and resolve an overheated CPU issue, the user should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the CPU if necessary. The user should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.

SAS stands for Serial Attached SCSI, which is a type of interface that connects storage devices to servers or workstations. SAS supports both mechanical hard disk drives (HDDs) and solid state drives (SSDs), but not other types of storage devices, such as NVMe M.2, mSATA, or optical drives12.

RAID stands for Redundant Array of Independent Disks, which is a method of combining multiple storage devices into a logical unit that provides improved performance, reliability, or both. RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping), which means that data is written across two or more striped sets of mirrored drives34.

Therefore, the only type of storage device that the technician can install in a server that only has SAS connectors and wants to use RAID 10 is mechanical HDDs. Mechanical HDDs use spinning platters and moving heads to store and access data, and they are usually cheaper and have larger capacities than SSDs, but they are also slower and more prone to failure .

The best way to protect the data of a virtual machine in the event of hardware failure is to use a cloud-based backup solution. A cloud-based backup solution is a service that copies and stores the data of a virtual machine to a remote server or storage device over the internet. A cloud-based backup solution can offer several benefits, such as:

High availability and reliability: A cloud-based backup solution can ensure that the data of a virtual machine is always accessible and recoverable, even if the hardware that hosts the virtual machine fails or is damaged. A cloud-based backup solution can also provide redundancy and fault tolerance, by replicating the data across multiple locations or regions.

Scalability and flexibility: A cloud-based backup solution can adapt to the changing needs and demands of the virtual machine, by allowing the user to adjust the backup frequency, retention period, and storage capacity. A cloud-based backup solution can also support different types of backup, such as full, incremental, or differential, depending on the user’s preferences and requirements.

Cost-effectiveness and simplicity: A cloud-based backup solution can reduce the cost and complexity of maintaining a backup infrastructure, by eliminating the need to purchase, install, or manage hardware, software, or licenses. A cloud-based backup solution can also automate and streamline the backup process, by providing easy-to-use tools and interfaces, such as web portals, APIs, or scripts.

Other options, such as redundant hardware, UPS, or RAID, may improve the performance or resilience of the hardware that hosts the virtual machine, but they do not provide a complete protection for the data of the virtual machine in the event of hardware failure. Redundant hardware is a technique that uses multiple components or devices to perform the same function, so that if one fails, another can take over. UPS (uninterruptible power supply) is a device that provides backup power to a system in case of a power outage or surge. RAID (redundant array of independent disks) is a technology that combines multiple disks into a logical unit, to improve the speed, capacity, or reliability of the storage. However, these options may not prevent data loss or corruption due to other causes, such as human error, malware, or natural disasters. Therefore, a cloud-based backup solution is the best way to protect the data of a virtual machine in the event of hardware failure.

Satellite internet is the most widely available internet connection type, as it does not depend on cables or wires. It can reach remote areas that lack infrastructure for other types of internet connections1. References: Satellite Internet
