A S.M.A.R.T. error is an indication of a potential failure of a hard drive. S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology and it is a feature that monitors the health and performance of hard drives. A hard drive test can help diagnose the issue and determine if the drive needs to be replaced.

A MD5 checksum is a value that is calculated from a file using a cryptographic hash function. A MD5 checksum is used to verify the integrity of a file by comparing it with the original value provided by the manufacturer or the source. If the MD5 checksums match, it means that the file is authentic and has not been corrupted or tampered with. If the MD5 checksums do not match, it means that the file is potentially corrupt or malicious and should not be installed12. A DLF configuration (A) is a setting that determines how a dynamic link library (DLL) is loaded into memory and executed by an application. A DLF configuration does not check the integrity of a file. A MBR failure (B) is a problem that occurs when the master boot record (MBR) of a disk is damaged or corrupted, preventing the system from booting. A MBR failure does not check the integrity of a file. ECC support is a feature that enables error-correcting code (ECC) memory to detect and correct data errors in RAM. ECC support does not check the integrity of a file. References: 1

The most likely solution to resolve the issue of the server crashing after running normally for approximately five minutes is to reinstall the heat sink with new thermal paste. A heat sink is a device that dissipates heat from a component, such as a processor or a graphics card, by transferring it to a cooling medium, such as air or liquid. A heat sink is usually attached to the component using thermal paste, which is a substance that fills the gaps between the heat sink and the component and improves thermal conductivity. Thermal paste can degrade over time and lose its effectiveness, resulting in overheating and performance issues. If a server crashes after running for a short period of time, it may indicate that the processor is overheating due to insufficient cooling.
To resolve this issue, the technician should remove the heat sink, clean the old thermal paste, apply new thermal paste, and reinstall the heat sink.

Components of a Data Loss Solution
Reference:
The best way to protect the data from leaking is to install a DLP solution. A DLP (Data Loss Prevention) solution is a software that helps businesses prevent confidential data from being leaked or stolen by unauthorized parties. A DLP solution can identify, monitor, and protect data as it moves across networks and devices, such as endpoints, email, web, cloud applications, or removable media. A DLP solution can also enforce security policies based on content and context for data in use, in motion, and at rest. A DLP solution can detect and prevent data breaches by using various techniques, such as content inspection, contextual analysis, encryption, blocking, alerting, warning, quarantining, or other remediation actions.
