Common Desktop PC Issues We Solve
At CAA Computers, we’ve seen it all when it comes to desktop PC problems. Whether it’s a slow computer, system crashes, or display issues, our expert technicians are here to help. Here are some of the most common desktop PC problems we repair:
Slow PC Performance
If your desktop has become sluggish, we’ll diagnose the bottleneck—whether it’s outdated hardware, lack of memory, or overloaded software—and optimise it or recommend strategic upgrades like SSD installations or RAM upgrades.
Boot-Up Problems
Is your PC stuck on the loading screen or refusing to boot? We fix BIOS errors, corrupted drives, and power supply issues to get your desktop PC back up and running quickly.
Random Crashes or Freezing
If your computer is randomly restarting or freezing mid-task, we’ll identify the root cause—be it faulty RAM, driver conflicts, or overheating components—and repair or replace what’s necessary.
Graphics & Display Issues
From black screens and no video output to flickering monitors or failing graphics cards (GPUs), we resolve both hardware and software issues for crisp, stable display performance.
Desktop Overheating Fix
Desktops with clogged fans or dried thermal paste can overheat and shut down. We offer full thermal cleaning, cooling upgrades, and airflow improvements to protect your system.
Why Regular Maintenance Is Key to PC Health
Waiting until your PC fails is costly and inconvenient. That’s why we provide affordable preventative maintenance services to keep your desktop performing at its best.
Internal Cleaning & Dust Removal
Built-up dust causes fans to clog, CPUs to overheat, and power supplies to fail. We clean your internal components thoroughly, improving thermal efficiency and performance.
Software Updates & Security Checks
We update your operating system, drivers, and essential software to improve performance and protect your data from vulnerabilities, viruses, and malware.
System Tune-Ups & Optimisation
From startup cleanup to drive defragmentation and system resource allocation, we keep your system running faster and smoother.
