Xigox is Milan Subway's leading independent specialist for Custom Computer repair. Our engineers are not generalists — they undergo dedicated training on Custom hardware, firmware and diagnostics. Since 2011, we have completed over 1,00,000+ repairs across all Custom product lines, earning a 4.9-star average customer rating.
Parts for Custom Computer models are held in stock rather than ordered after you book, so most repairs are not waiting on a supplier. Screens, batteries, keyboards, charging boards and flex cables are all OEM-grade. You approve a written estimate first, and the ₹350 inspection is credited back against the repair.
We actively serve the entire 400054 postal area within Mumbai Suburban district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair). Located near Milan Subway Road, our service coverage extends across Milan Subway and all surrounding localities. In addition to Milan Subway, we also provide doorstep repairs and free pickup for lab work for customers in Santacruz West, Santacruz, Vakola and other nearby areas.
How your Custom Computer gets serviced depends on the fault. Part swaps happen on-site anywhere in Milan Subway; board-level work goes to the bench because it needs proper rework equipment. Either way collection and return are free, and you get progress updates rather than having to chase us.
We back Custom work with a 90-day parts-and-labour warranty in writing, not just a verbal promise. If your Computer does come back with the same fault, we cover it. You keep a direct WhatsApp line to the team that did the work.

Product lines
At our bench we handle Computer GPU Upgrade on the Custom Gaming PC range; the models are listed below.
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.
A Custom Office PC is a desktop built from individually selected components for everyday office/productivity use rather than gaming or heavy workloads.

How it's done
What our technicians do, what it requires, and how to tell you need it.
For an upgrade rather than a repair, we run a stress test alongside thermal imaging to confirm whether artifacts or crashes are a genuine GPU fault versus a cooling or driver issue, since those three causes look very similar on the surface but need completely different fixes.
Typical time: 1–4 hours
Tired of middlemen? Work with the actual repair team — Xigox. Desktop PC diagnostics in Milan Subway need a different approach than laptop repair — a POST card, PSU tester, and RAM slot isolation. Xigox technicians use a methodical component-isolation sequence: starting from the most common fault point outward. This prevents unnecessary parts purchases — you don't replace a ₹8,000 GPU if the PSU is the real fault.
Quality matters for the repair. Because of this, our team strictly use genuine parts for your Custom. Instead of unbranded components, we use trusted supply chains. This guarantees your repair will last, supported by our standard 90-day warranty.
Replacing an entire board is often unnecessary than fixing the fault on it. Xigox's in-house chip-level facility means engineers diagnose the exact failing IC and replace only that component — a fraction of full board replacement. Milan Subway residents seek us out for chip-level issue.
Each repair performed by Xigox in Milan Subway comes with a comprehensive 90-day warranty covering parts and labour. Simply put, if the same issue recurs within 90 days, we redo it completely free. Xigox issues a printed warranty receipt every single time, so you know exactly what is covered.
Xigox isn't just for individuals Milan Subway rely on our issue to keep operations running. Our corporate solutions include bulk repair contracts, guaranteed 4-hour response times, and dedicated account managers.

Many Milan Subway customers wonder whether an extended warranty applies to the repair. Xigox supports insurance claims and can provide the itemised bill your insurer needs — including parts cost, labour cost, and fault description.
