Desktop Computer Repair Service

AlightTech provides desktop computer repair for home users, offices, shops and commercial establishments. We troubleshoot both hardware and software-related problems and help customers maintain their computers for better performance.

Our desktop repair services include hardware diagnostics, component replacement, Windows-related problems, storage upgrades, RAM upgrades, power issues, overheating and performance troubleshooting.

Motherboard Repair Service

The motherboard is one of the most important components of a computer. Problems with the motherboard can cause no power, no display, USB failure, LAN problems, continuous restarting and other system issues.

Our technicians can diagnose common motherboard-related problems and determine whether repair or component replacement is the most suitable option.

Common Motherboard Problems
  • No Power
  • No Display
  • System Restarting
  • USB Port Not Working
  • LAN Port Not Working
  • BIOS/Boot Problems
  • Hardware Detection Problems
  • Short Circuit Related Issues

We support motherboards used with Intel and AMD-based desktop systems and work with popular brands such as Intel, ASUS, Gigabyte, Dell, HP and other major manufacturers.

CPU & Processor Troubleshooting

If your desktop computer is hanging, restarting, overheating or running extremely slowly, the problem may be related to the processor, cooling system, motherboard, RAM or power supply.

Our technicians inspect the complete system rather than replacing components unnecessarily. We check the processor, CPU fan, thermal condition, RAM, motherboard and power supply to identify the actual cause.

CPU-Related Problems We Handle
  • Computer Hanging
  • Very Slow Performance
  • Frequent Restart
  • Overheating
  • No Display
  • Windows Not Starting
  • CPU Fan Problems
  • Operating System Issues

Hard Disk, SSD & Data Recovery Assistance

Storage failure can be a serious problem, especially when important personal or business data is involved. AlightTech provides hard disk and SSD troubleshooting and can assist with data recovery requirements depending on the condition of the storage device.

Common Hard Disk Problems
  • Hard Disk Not Detected
  • Incorrect Storage Capacity
  • Slow Hard Disk
  • Bad Sector Related Problems
  • Operating System Failure
  • Hard Disk Logic/PCB Issues
  • Data Access Problems

Important: If a hard disk is making unusual noises or suddenly stops working, avoid repeatedly switching it on, as this can potentially make data recovery more difficult.

LED & LCD Monitor Repair Service

A faulty monitor can make a perfectly working computer appear to be defective. AlightTech provides LED and LCD monitor repair services for various display-related problems.

Our technicians can troubleshoot issues such as:
  • No Display
  • Blank Screen
  • Flickering Display
  • Lines on Screen
  • Dim Display
  • Power Problems
  • Display Connector Problems
  • Adapter/Power Board Problems

We diagnose the monitor before recommending repair or replacement.

Virus & Malware Removal Service

Viruses and malware can affect computer performance, damage files and create security risks. If your computer has become unusually slow, shows unwanted pop-ups or behaves abnormally, professional troubleshooting may be required.

Our virus and malware removal service includes system inspection, malware cleanup, security checks and basic system optimisation.

We also provide professional assistance with Windows and software-related issues, including:

  • Startup Error Fixing
  • Software Compatibility Issues

We recommend using genuine and properly licensed software wherever applicable.

We can assist with:
  • RAM Upgrade
  • SSD Upgrade
  • Hard Disk Replacement
  • Processor Upgrade
  • Power Supply Replacement
  • CPU Cooling Upgrade
  • Cabinet and Cooling Solutions

An SSD and additional RAM can often make a significant difference to the performance of compatible desktop computers.
