MSI Modern AM242 AIO — Webcam Fix

“Built-in webcam on my MSI Modern AM242 AIO showed only a black screen during meetings. Xigox Khar replaced the tiny camera module inside the bezel without damaging the screen. Clear video quality restored. Delicate, precise work.”
R Rupal Trivedi Fort · 26 Oct 2024 13

Intel NUC 13 Pro — PC Troubleshooting

“Our office Intel NUC 13 Pro was freezing constantly and making loud buzzing noises. Xigox Khar replaced the dead CPU cooler, applied fresh thermal paste, and cleaned all dust. Runs whisper-quiet now. Excellent work.”
G Girish Jog Fort · 19 Jul 2025 13

Dell XPS 8960 — BSOD Fix

“My Dell XPS 8960 showed constant blue screen of death errors. Xigox Khar ran extensive diagnostics and found a bad RAM module. Replaced it and updated all drivers. Rock-solid stability since the repair. Efficient diagnosis.”
J Jyoti Kulkarni Fort · 17 Jan 2026 18

Mac Pro M2 Ultra — Power Supply Fix

“My Mac Pro M2 Ultra started experiencing sudden shutdowns during gaming sessions and heavy rendering workloads, which initially made me suspect overheating but the temperatures were all perfectly normal. The Xigox Khar technician diagnosed the power supply by testing it under load and identified significant voltage drops on the twelve-volt rail under moderate power draw, which meant the PSU was failing to deliver sufficient power to the GPU and CPU simultaneously. They replaced it with a high-quality eighty-plus gold rated power supply with adequate wattage headroom for my components, routed all cables neatly for optimal airflow, and also added a UPS recommendation for power surge protection during Mumbai monsoons. The system now handles intensive gaming and rendering sessions for hours without a single shutdown. The improved cable management also reduced internal temperatures by approximately five degrees. Extraordinary power supply work — The follow-up call after the repair really showed they care about customers.”
V Vandana Kadam Fort · 18 Mar 2026 20

Custom Workstation — OS Installation

“Windows on my Custom Workstation was corrupted beyond repair. Xigox Khar performed a clean installation, migrated all my files, reinstalled essential software, and configured drivers. Boots fast and runs perfectly now.”

It depends on the age and value of the computer. As a rule, if the repair costs less than a third of a comparable replacement and the rest of the hardware is healthy, repairing is worth it.

We use OEM or OEM-grade components and tell you which one your quote covers before work starts.

Free pickup also available in Kabutar Khana, Mantralaya, Flora Fountain and surrounding areas.
That is what the ₹350 inspection is for. Symptoms overlap constantly — the same visible behaviour can come from three different components. We test rather than guess, then show you what we found before quoting. If the actual fault turns out to be something cheaper, the quote reflects that. Free pickup also available in Kabutar Khana, Mantralaya, Flora Fountain and surrounding areas.
