About This Repair

Custom Gaming PC Repair in Rickmansworth

Custom-built gaming PCs are passion projects — hand-picked components, carefully cable-managed builds, and years of gaming memories. At Mr Gadget in Rickmansworth we diagnose and repair custom gaming PCs for GPU faults, overheating, PSU failures, motherboard issues, and performance problems.

Custom PC diagnostics require methodical component isolation — ruling out GPU, CPU, RAM, PSU, and storage one by one. We have the test bench and spare components to quickly identify the failing part. We'll give you a full diagnostic report and repair quote before any work begins.
