Gaming PC Repair & Upgrades in London
Diagnostics and upgrades for gaming computers with crashes, overheating, boot problems, unstable performance or hardware failures.
We look beyond the obvious symptom.
Gaming PCs can fail under load even when they appear normal at the desktop. We look at temperatures, power delivery, memory, storage, drivers and individual components to isolate crashes, instability and performance problems.
Forest City Computers serves customers from across London, Ontario. In-shop diagnostics are available for many common computer problems, and no appointment is required for regular walk-in service.
