Custom PC Troubleshooting Sheffield
Fix custom PC build issues in Sheffield - POST failures, no display, instability, compatibility problems and BIOS configuration.
Custom PC Won't POST or Boot? Here's What We Do
Building a custom PC is rewarding - but when it won't POST, won't display, or crashes within minutes of loading Windows, troubleshooting can be frustrating and time-consuming. Custom build issues are often caused by subtle problems: a RAM kit that needs XMP enabling, a GPU requiring a BIOS update before it's supported, a power header connected to the wrong pins, or a component that arrived dead out of the box (DOA).
We work through the build systematically - testing each component, checking compatibility, verifying BIOS settings and seating - until we isolate the fault. We can also advise on component choices, compatibility issues and optimal BIOS configuration for your specific hardware.
See our full desktop PC repair page for all faults we cover.
