Custom builds, upgrades, overheating, GPU replacement, and full repairs for desktops and gaming PCs. All brands, all configurations.
From R345Desktop & Gaming PC Repair Services
Whether you have a home office desktop, a workstation, or a high-end gaming rig, Asetos Computers in Rosebank repairs and upgrades all desktop configurations. From budget office PCs to custom-built gaming machines with multiple GPUs and liquid cooling, we've worked on them all.
Desktop PCs are more modular than laptops, which means most components can be individually replaced or upgraded. This makes them excellent value to repair rather than replace. A power supply failure, for example, is a R500–R1,500 fix, not a reason to buy a new PC.
Common Desktop Problems We Fix
- Won't turn on: power supply, motherboard, or power button failure
- Overheating and thermal throttling: dust buildup, fan failure, thermal paste degradation
- Random shutdowns and blue screens: RAM issues, driver conflicts, overheating
- Slow performance: HDD to SSD upgrade, RAM upgrade, OS reinstall
- GPU failure: artefacts on screen, no display output, fan noise
- Virus and malware: deep clean, OS reinstall, security hardening
- Network connectivity issues: WiFi adapter, ethernet port, driver problems

Gaming PC Services
Gaming PCs require specific expertise: high-wattage power supplies, dedicated GPUs, aftermarket cooling, RGB lighting, and performance tuning. We handle GPU upgrades and replacements for NVIDIA and AMD cards, CPU upgrades including thermal paste and cooler installation, RAM upgrades for gaming performance (16GB minimum, 32GB recommended), SSD upgrades for faster game load times, custom cable management and case airflow optimisation, and performance diagnostics including benchmarking before and after.
Custom PC Builds
Need a new desktop built to your specifications? We source components from local suppliers, assemble the system, install your operating system, run stress tests, and deliver a machine configured exactly how you want it. Whether it's a budget office PC, a mid-range workstation, or a high-end gaming build, we handle the entire process so you get exactly what you need without compatibility headaches.
