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, our technicians check the GPU's solder joints and VRM components for the specific failure signatures common to its chip generation, re-flow or repair at the component level where the board design allows it, and verify stability under sustained load — not just a quick idle test.
Typical time: 1–4 hours
The model
The Dell Precision 3660 is Dell's workstation line — ISV-certified (for software like AutoCAD, SolidWorks) with ECC memory options and professional-grade GPUs, built for engineering, architecture, and data-science workloads.
Why waste time on aggregators? Get direct service without middleman markup with Xigox. Dell Precision 3660 PC Graphics Card Upgrade for desktops differs significantly from laptop repair: open chassis design, full-size components, and tower airflow. Our engineers use oscilloscope diagnostics and stress testing to identify PSU ripple, GPU thermal issues, and RAM timing errors — recommending targeted component replacement.
Numbers speak louder. Xigox maintains a 4.9-star rating from 9,605+ customer reviews from customers across Mumbai MMR. Common praise includes: no surprise charges, fast turnaround, and genuine parts. What Null Bazaar customers value most: "Fast, professional service with fair pricing." Become part of the growing community of satisfied Xigox customers in Null Bazaar.
The biggest frustration about repair shops in Null Bazaar is surprise bills after the job is done. We've built our entire model around transparency. Prior to touching your Dell, our technician provides a clear cost estimate that covers everything. You see the exact cost — approve it or decline, no pressure. Our ₹350 inspection fee is fully refunded when you proceed with this issue.
Businesses across Null Bazaar trust our repair to keep operations running. We offer bulk repair contracts, same-day priority service, and a single point of contact. From a small team or an entire floor, Xigox manages the repair for your Null Bazaar workspace with GST invoices and complete service reports.
Many Null Bazaar customers wonder whether their laptop insurance covers this issue. We help with insurance claims and can generate the detailed GST invoice required for claim submission — broken down by component and labour. When manufacturer warranty has expired, our repair is almost always often far cheaper compared to the brand's authorised centre.
Your Dell model doesn't limit what we can fix. Our technicians are brand-agnostic experts: HP, Dell, Lenovo, Asus, Acer, MSI, Toshiba, Samsung and Apple MacBook. Each brand has quirks in their assembly that our team knows well. Model-specific experience cuts diagnostic time and improves first-time fix rates.

If you notice anything unusual in the post-repair period, just reach out and we dispatch a technician immediately. This promise is why Null Bazaar customers choose Xigox again and again.
Completing the repair is just the first step at Xigox. Prior to delivery in Null Bazaar, it undergoes a rigorous full-system inspection. We verify that your repair was executed flawlessly, testing thermal performance. This attention to detail is why our return rate is so low across Null Bazaar.
