A gaming PC is more than just a computer. For many users, it’s a significant investment used for gaming, streaming, content creation, video editing and everyday performance-intensive tasks.
When a gaming PC develops a fault, performance can quickly suffer. Frame rate drops, overheating, crashes and boot failures can make even high-end systems frustrating to use.
At Archway Tech Repairs, we provide professional gaming PC repair services for customers across London. Whether you own a custom-built system or a pre-built gaming PC, our technicians can diagnose hardware and software issues and recommend practical repair solutions.
From GPU faults and overheating problems to power issues and upgrade services, we help keep gaming systems running reliably.
Common Signs Your Gaming PC Needs Repair
Gaming PCs often show warning signs before a major failure occurs.
Common symptoms include:
- FPS drops during gaming
- Random crashes
- Blue screen errors
- Overheating
- Loud fan noise
- System freezing
- PC not turning on
- Display issues
- Unexpected restarts
- Slow performance
Identifying these issues early can help prevent further hardware damage and improve system reliability.
Gaming PC Not Turning On
One of the most common issues we diagnose is a gaming PC that refuses to power on.
Potential causes include:
- Power supply failure
- Motherboard faults
- Faulty RAM
- CPU issues
- Power connection problems
Many customers assume their system is beyond repair when the issue may be limited to a single component.
Professional diagnostics help identify the exact cause before unnecessary replacements are considered.
Gaming PC Overheating
Modern gaming hardware generates significant heat.
If cooling systems are not functioning properly, temperatures can rise quickly and affect performance.
Common overheating symptoms include:
- FPS drops
- Loud fans
- Thermal throttling
- Unexpected shutdowns
- High CPU temperatures
- High GPU temperatures
Causes may include:
- Dust build-up
- Faulty cooling systems
- Worn thermal paste
- Poor airflow
- Failing fans
Addressing overheating early helps protect expensive components and improve long-term reliability.
Graphics Card Problems
The graphics card is one of the most important components in a gaming PC.
GPU-related issues may cause:
- No display output
- Screen artefacts
- Game crashes
- Driver errors
- Performance drops
- Random black screens
Because graphics cards represent a significant investment, professional diagnosis can help determine whether repair, replacement or optimisation is the most practical solution.
Blue Screen Errors & System Crashes
Blue screen errors are often frustrating because the cause is not always obvious.
Potential causes include:
- RAM faults
- Driver conflicts
- Storage failures
- GPU problems
- Motherboard issues
A diagnostic assessment helps identify the root cause rather than guessing which component is responsible.
Slow Gaming Performance
Many gamers contact us because their system no longer performs as it once did.
Performance issues can be caused by:
- Hardware degradation
- Thermal throttling
- Insufficient memory
- Storage bottlenecks
- Driver issues
- Background software conflicts
Optimisation and hardware upgrades can often restore performance without replacing the entire system.
