History
Established in 2014.
Grand Fusion Computers was built from years of hands-on experience with custom PCs, upgrades, troubleshooting, and everyday computer support. Ivan Sigaev has been working with computers for about 16 years, starting with personal builds and repairs, then helping friends, family, and local clients with reliable PC setup, maintenance, and problem solving.
The business focuses on practical, clean, and honest computer service: custom PC builds, upgrades, diagnostics, Windows setup, driver installation, cleaning, cable management, airflow checks, and remote support. Every job starts with understanding what the customer actually needs, then finding the best solution without unnecessary upsells.
Meet the Business Owner: IVAN S.
Hi, I’m Ivan, the owner of Grand Fusion Computers. I’m passionate about building clean, reliable computers and helping people get the most out of their systems.
I work directly with each customer, whether it’s a custom gaming PC, an upgrade, a slow computer, Windows setup, driver issues, or general troubleshooting. My goal is to make the process simple, clear, and practical, with honest recommendations and careful attention to detail.
I do not perform soldering, motherboard-level repair, GPU board repair, or liquid-damage repair, but I’m happy to help with diagnostics, upgrades, setup, cleaning, and everyday computer support.
