Root Cause Analysis

Why Does Computer Slow Performance Happen on ASUS Devices?

Knowing the root cause ensures a precise repair — not just a temporary fix.

Failing Storage

A failing HDD or SSD causes read/write bottlenecks, freezes and system slowdowns.

Insufficient RAM

Running too many apps on limited RAM forces the system to use slow virtual memory.

Thermal Throttling

A clogged heatsink or dry thermal paste causes the CPU to throttle speed to prevent damage.

Malware / Bloatware

Background processes from malware or pre-installed software silently consume CPU/RAM.

If you are looking for ASUS Computer / Laptop repair in Kelve Naka that is not a brand service centre, this is it. Xigox has run an independent ASUS bench since 2011, and our technicians work on ASUS boards and firmware every day rather than treating them as an occasional job.

Every ASUS component we fit is OEM-grade and batch-tested before it goes into your Computer / Laptop — no aftermarket substitutes, no recycled pulls sold as new. You see the part cost and the labour cost separately on the estimate before we start, and the ₹350 inspection comes off the bill if you go ahead.

We actively serve the entire 401401 postal area within Palghar district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair).

How your ASUS Computer / Laptop gets serviced depends on the fault. Part swaps happen on-site anywhere in Kelve Naka; 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.
