Understand why expert service protects your Custom laptop or computer and extends its lifespan
Upgrading from HDD to NVMe SSD delivers 5–10× faster boot times, app launches and file transfers.
SSDs consume significantly less power than HDDs, giving your Custom Computer longer battery life.
Unlike HDDs, SSDs have no moving parts — they're shock-resistant and far less likely to fail.
An SSD upgrade can give an old Custom Computer 3–5 more years of productive use.

Product lines
At our bench we handle Computer OS Upgrade on the Custom Office range; the models are listed below.
A Custom Office PC is a desktop built from individually selected components for everyday office/productivity use rather than gaming or heavy workloads.
A Custom Gaming PC is a desktop built from individually selected components rather than a pre-built model line — the specific parts, cooling, and capabilities vary entirely by build, so diagnosis always starts with identifying exactly what's installed.

How it's done
What our technicians do, what it requires, and how to tell you need it.
When you want more capacity or speed rather than just a fix, for an installation or reinstall, we back up your existing files first, install a genuine, correctly licensed copy of the operating system, and install the specific driver set your exact hardware model needs — not a generic driver pack that happens to install without errors.
Typical time: 30–90 minutes
Don't waste time on booking portals. Reach the engineers directly with Xigox. Capacitor failures on desktop PC motherboards in Sion are one of the most frequent desktop issues on boards 5–10 years old — particularly in coastal and humid environments. Xigox's board-level engineers identify and replace individual capacitors rather than condemning the entire board: significant cost saving through component-level work. For Custom Computer OS Upgrade in Sion specifically, Xigox follows this exact process from start to finish — free pickup, transparent written quote, genuine-grade parts, and a 90-day warranty on the completed Custom Computer OS Upgrade.
