Single component 30-60 minutes. Full system upgrades with OS migration take 3-5 hours.
Absolutely. Data security is our top priority. Our technicians never access personal files during Dell Precision 3660 Computer Workstation GPU Upgrade.

Xigox handles Dell Precision 3660 Computer Workstation GPU Upgrade for all major brands in Charkop, including Apple, HP, Dell, Lenovo, Asus, Acer, MSI, Intel and custom-built systems — and many more. No brand or model is too complex — we repair them all. We also serve Poisar, IC Colony, Borivali West, so you can recommend us to neighbours too.
Yes — ₹350 for the inspection in Charkop. Our technician diagnoses your computer and gives you a clear written estimate; if you go ahead with the repair, that ₹350 is adjusted against the total cost, so the inspection itself doesn't add to the bill. If you decide not to proceed, the ₹350 still applies for the technician's time. Customers near Link Road in Charkop are covered by our free pickup.
We accept all major payment methods for Dell Precision 3660 Computer Workstation GPU Upgrade in Charkop: UPI (Google Pay, PhonePe, Paytm), debit/credit cards, net banking, and cash. Payment is collected after the repair is completed to your satisfaction — we never charge upfront without consent. Customers near Link Road in Charkop are covered by our free pickup.
Yes — out-of-warranty computers are most of what we handle in Charkop. Once the manufacturer warranty lapses, authorised centres often quote near-replacement prices for a single component. We repair at component level where it is safe to do so, which is usually a fraction of that cost, and back it with our own 90-day warranty. We also serve Poisar, IC Colony, Borivali West, so you can recommend us to neighbours too.
You pay nothing beyond the ₹350 inspection. If we cannot resolve the fault, we explain exactly what we found, return your computer in the condition we received it, and — where the economics do not justify a repair — tell you so plainly rather than selling you work that is not worth doing. Our service covers the full 400067 postal area in Charkop.
For software faults, setup, upgrades and diagnostics we can work on-site anywhere in Charkop. Component-level work — board repair, screen bonding, liquid-damage recovery — needs workshop equipment, so we collect the computer, repair it, and return it. Both options are free of travel charges. Trusted by customers throughout Mumbai Suburban — rated 4.9★ across 9,727+ reviews.
We send live updates over WhatsApp at each stage: collection, diagnosis, quote approval, repair completion, and dispatch. You can reply to that thread at any point to reach the technician handling your computer rather than a general helpline. Customers across Charkop (400067) enjoy priority same-day scheduling.
Back up documents, photos and anything stored only on that computer before any repair — with us or anyone else. Most Dell Precision 3660 Computer Workstation GPU Upgrade work does not touch your data, but board-level faults and storage failures can be unpredictable. Tell us in advance if the drive holds irreplaceable data and we will treat recovery as the first priority. Free pickup also available in Poisar, IC Colony, Borivali West and surrounding areas.

We stock genuine Dell parts and OEM-compatible components for every common Dell Precision 3660 fault — from screen replacements and battery swaps to logic board repairs and data recovery. Before any work begins, you receive a written cost estimate. Our ₹350 inspection fee is refunded if you proceed with the repair.

How it's done
How We Perform Computer Workstation GPU Upgrade
What our technicians do, what it requires, and how to tell you need it.
1 How It's Performed
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
2 What This Requires
- On desktops: confirmation of power-supply headroom before any card upgrade, since an underpowered PSU can mimic GPU instability symptoms.
- A clean driver reinstall as part of the verification step, ruling out software before any hardware conclusion is reached.
3 When You Need This
- Visible screen artifacts — colored specks, stripes, or garbled graphics — especially under graphics-heavy load.
- Crashes or black screens specifically during gaming or video editing but not during light browsing.
- The fans spin up loudly under load far more than they used to, alongside any of the above.
