Desktops are easier to service than laptops but failures still range from a loose cable to a dead motherboard. This guide covers the issues we see most at our Edmonton bench.
No power at all
Check the outlet, power strip, and rear PSU switch. If the PC is completely dead, the PSU is a common culprit — but we verify before swapping parts. Liquid damage and surge events need inspection before powering on again.
Slow or freezing
Full drives, failing HDDs, and malware are top causes. An SSD upgrade often transforms an older tower. See our slow computer guide for detailed steps.
Blue screens and crashes
Repeated BSODs often trace to RAM, storage, drivers, or heat. Document stop codes and note whether crashes happen under load or at idle. Our BSOD guide explains common codes.
Custom gaming PCs
Custom builds need proper cooling, PSU headroom, and stable RAM profiles. Random game crashes may be thermal throttling or insufficient power — not always a bad GPU.
Upgrades vs replace
Many towers accept RAM, SSD, and GPU upgrades for years. We assess whether repair and upgrade makes sense vs replacement — honest advice is part of every diagnostic.
