In a fast-paced city like London, a computer breakdown is more than just a technical issue—it can stop work, delay deadlines, and directly affect income. Many customers try temporary fixes or online solutions, but when problems keep returning, professional help becomes essential.
This detailed case study explains how Hire IT Expert, a trusted computer repair service in London, handled a real customer situation—from the first call to the final resolution—using a structured, expert-led approach. This is not a promotional story, but a realistic example of how professional computer repair should be done.
Background: Why the Customer Contacted Hire IT Expert
The customer was a self-employed consultant based in East London, relying heavily on a desktop PC for:
- Client emails
- Online meetings
- Accounting and invoicing software
- Printer and scanner usage
For almost three weeks, the system had become unreliable. The customer initially ignored the warning signs, assuming it was a temporary slowdown. However, the situation gradually worsened.
After searching online for “computer repair London” and “PC repair near me”, the customer contacted Hire IT Expert due to clear service details and local expertise.
Device & System Details
- Device Type: Desktop PC
- Operating System: Windows 11
- System Age: Approx. 3.5 years
- Usage Type: Business & office work
- Previous Repairs: None
The customer requested on-site computer repair in London as the system could not be transported easily.
Issues Reported During the First Call
During the initial discussion, the customer described multiple problems:
- Extremely slow startup and shutdown
- Random freezing while working
- Occasional blue screen errors
- Printer disconnecting repeatedly
- Software crashing without warning
- Antivirus pop-ups appearing frequently
These symptoms clearly indicated that the issue was not a single fault, but a combination of software, system, and performance problems.
Step 1: Professional On-Site Diagnosis
Once our computer expert in London arrived, the first step was a complete system diagnosis instead of immediate repairs.
System Performance Analysis
- Checked CPU, RAM, and disk usage
- Identified abnormal background processes
- Noted unusually high disk activity
Startup & Software Review
- Found multiple unnecessary startup programs
- Detected partially uninstalled software
- Observed system conflicts after recent Windows updates
Hardware Health Check
- Hard drive showing slow response times
- No physical hardware damage
- RAM functioning correctly
Step 2: Security & Malware Inspection
A deeper scan revealed a major hidden issue.
Although the customer had antivirus installed, it was outdated and conflicting with Windows Security. This caused:
- Hidden malware processes running in the background
- High CPU and disk usage
- System instability and crashes
Our expert safely isolated and removed these threats without risking data loss.
Step 3: Identifying the Root Causes
After thorough testing, the real causes of the problem were identified:
- Corrupted Windows system files
- Malware consuming system resources
- Driver conflicts after Windows updates
- Poor disk optimisation
This confirmed that simply reinstalling software would not have solved the issue permanently.
