I found this shop on Google and saw it had great reviews from many customers. I recently brought in my ASUS laptop to have the storage upgraded to an SSD and for general servicing. The shop provided excellent service and proved to be trustworthy and reliable. The staff was professional, attentive, and made sure I understood the entire process. My laptop is now running faster and more efficiently. I highly recommend this place to anyone needing laptop upgrades or repairs.

What's going on

A desktop that's slowed down over time is rarely just old. More often it's a mechanical hard drive nearing the end of its life, too many background programs competing for RAM, or a cooling system so clogged with dust that the CPU is throttling itself to avoid overheating. We check Task Manager, drive health and thermal behaviour to find the actual bottleneck before recommending a fix — usually an SSD upgrade is the single biggest improvement for an older desktop still running on a mechanical drive.

Common signs to look out for

  • Boot-up takes several minutes
  • Programs freeze or become unresponsive
  • Disk usage sits at 100% in Task Manager during normal use
  • Fans ramp up loudly even during simple tasks
  • Storage is always nearly full

What usually causes it

  • An aging mechanical hard drive (HDD)
  • Insufficient RAM for current workloads
  • Malware, bloatware or excessive startup programs
  • Thermal throttling from a dust-clogged cooling system
  • An outdated operating system version

How we diagnose this

01

Task Manager diagnostic

We check CPU, RAM and disk usage to see exactly where performance is being lost.

02

Storage & RAM audit

We confirm whether the bottleneck is drive speed, drive capacity, or insufficient memory.

03

Thermal check

We rule out dust-related thermal throttling as a contributing cause.

04

Recommend & retest

Depending on the cause, that's an SSD upgrade, a RAM addition, or a clean-up — retested before handover.

Common questions

Desktop slow performance FAQs

Usually not. A desktop that's slowed down over time is rarely just old — it's more often a mechanical hard drive nearing end of life, insufficient RAM, or dust-related overheating, all of which are fixable at a fraction of the cost of a new machine.
Diagnosis starts from RM 150. If an SSD upgrade or RAM addition is needed, that's priced separately based on the capacity you choose.
Typically same-day, including an SSD upgrade if that's part of the fix — desktops are usually faster to work on than laptops since components are easier to access.
Same-day is common when the part is in stock and the fault is straightforward — the Same day window mainly accounts for part availability for less common desktop models. We confirm your actual timeline after diagnosis, not just the general range.
No — protecting your data is treated as seriously as the hardware fix itself. Where a repair could plausibly affect stored data, we back up what's accessible before starting work, and we never wipe or reformat a drive without your explicit go-ahead. If your desktop won't boot at all, ask us about data recovery before assuming anything is lost.
Every repair carries our Standard Component Warranty, terms and conditions applying to labour and the fix itself. If a replacement part carries its own separate manufacturer or supplier warranty — batteries and SSDs typically do — that can extend further depending on the specific part, and we tell you exactly what applies to your repair before any work begins.
No. Basic live-agent assessment is always free at Dotronix, whether you approve the repair afterward or not. You only pay if you say yes to the quote we send you.
Both work, shaped to each hub. Book ahead with Our Live Agent for a guided workshop visit in Kepong, or visit our Kuchai Lama branch — call/WhatsApp first to confirm availability. Either way you get the same diagnosis and pricing.
