FAQ

FAQs — HP ProDesk 400 G9 Computer GPU Upgrade in Zai

Everything you need to know before booking your repair

10 questions answered

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 HP ProDesk 400 G9 Computer GPU Upgrade. We follow strict protocols to prevent data loss, and we'll always inform you before any procedure that could affect stored data. Your privacy is fully protected. Customers near Dahanu Station in Zai are covered by our free pickup.
Xigox handles HP ProDesk 400 G9 Computer GPU Upgrade for all major brands in Zai, 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 Ganjad, Betegaon, Chinchani, so you can recommend us to neighbours too.
Yes — ₹350 for the inspection in Zai. 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. Trusted by customers throughout Palghar — rated 4.9★ across 9,727+ reviews.
We accept all major payment methods for HP ProDesk 400 G9 Computer GPU Upgrade in Zai: 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. Our service covers the full 401602 postal area in Zai.
Yes — out-of-warranty computers are most of what we handle in Zai. 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 Ganjad, Betegaon, Chinchani, 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 401602 postal area in Zai.
For software faults, setup, upgrades and diagnostics we can work on-site anywhere in Zai. 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. Customers across Zai (401602) enjoy priority same-day scheduling.
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. We've been serving Palghar district for over 15 years.
Back up documents, photos and anything stored only on that computer before any repair — with us or anyone else. Most HP ProDesk 400 G9 Computer 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 Ganjad, Betegaon, Chinchani and surrounding areas.

How it's done

How We Perform Computer GPU Upgrade

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

When you want more capacity or speed rather than just a fix, 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

  • A proper stress test (not just a visual check) to separate a real GPU fault from a thermal-throttling or driver problem — these three causes are frequently confused.
  • Thermal imaging equipment to spot a reflow-able solder fault before assuming a full chip replacement is needed.

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.
