Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.

A sandbox environment is designed to isolate and contain software or programs, preventing them from interacting with other parts of the system or network. This isolation can be used to safely run untested or untrusted programs or code without risking the integrity of the host system or network. Setting up a virtual machine within a sandbox environment ensures that the VM has no communication with other devices over the network, providing a controlled and secure environment for testing or development purposes.

Secure Shell (SSH) is a protocol used to securely access and manage devices over a network. It provides a secure channel over an unsecured network in a client-server architecture, enabling technicians to perform troubleshooting and management tasks remotely with encryption to ensure the security of the data transmitted. FTP and TFTP are used for file transfers and do not inherently provide the same level of security or direct device management capabilities. RDP is used for remote desktop connections but is not as universally applicable for various devices as SSH.

When a computer frequently freezes and requires hard restarts, the first step a technician should take, especially when hardware components have not been recently changed, is to read the event logs. Event logs can provide critical insights into what is causing the system to freeze, including errors and warnings that precede the freeze. This information is essential for diagnosing software or operating system issues that might be causing instability. Checking the temperature or updating drivers might be subsequent steps based on findings from the event logs.
