For bilingual PC and Mac repair in Chula Vista, Javier's Computer Repair has served residential and commercial clients from its G Street location since 2010. CompTIA, Cisco, Dell, HP, and Lenovo certifications back the shop's hardware troubleshooting on both consumer laptops and enterprise server racks, covering the computing side of the electronics-repair ecosystem where Chula Vista TV handles display and audiovisual components. Services span motherboard-level diagnosis, GPU and RAM upgrades, data recovery from failing drives, virus removal, and full network-infrastructure builds for small businesses. The security-camera division designs and installs IP-based surveillance systems with remote-access configuration and NVR setup, extending the shop's commercial-IT scope into physical-security integration alongside access-control specialists at Busy Bees Locks & Keys Locksmith. Enterprise-tier projects include multi-switch Cisco network deployments with VLAN segmentation, firewall configuration, and centralized backup solutions for offices running 20 or more workstations.
