Software Installation
Report
Software installation refers to configuring and preparing applications required to operate on a computer. It includes placing program files in correct system directories, adjusting settings, and creating shortcuts for proper integration. Data migration involves transferring personal files and system preferences from an old PC to a new one. Together, they ensure a smooth transition.
Custom Builds
Report
Custom Builds refers to computers assembled from individually selected components, allowing us to design systems tailored to specific requirements. We choose parts such as CPU, GPU, motherboard, RAM, storage, PSU, and case. This approach provides precise performance, improved cost efficiency, and enhanced control over quality. The process includes planning, selecting compatible parts, and manual assembly.
We emphasize the importance of reliable data backups in protecting critical information. Backups safeguard against accidental deletion, corruption, system failures, and cyber threats such as ransomware. They support business continuity, compliance obligations, and help maintain customer trust while reducing recovery costs. We also use them to recover from human error, hardware damage, and other data loss scenarios.

My husband and I have zero computer skills. Patrick was extremely patient and calm while explaining what he needed to do. His fee was very reasonable.
