Trusted Custom & Gaming PC Repair Services
The most important step in any repair is a correct diagnosis, and on a gaming rig that means knowing whether a no-display is the GPU, the RAM, the board, or the PSU. Consistently nailing it takes years of building and fixing these machines, which is why a specialist beats guesswork.
Whether it needs a repair, a GPU and cooling upgrade, or a fresh custom build, we tell you honestly what makes sense and quote before any work begins.
Meet the Team Behind DC Computers
DC Computers is owned and run by Daniel & Chris, yes, the "D" and the "C." We are builders ourselves, so when you bring in a gaming rig you are handed to the same crew that assembles and repairs custom PCs every day.
No call centers and no mail-in black holes, just local techs who diagnose honestly, explain your options in plain English, and treat your build (and your data) like it's their own.

🖥️ No Display / Black Screen
Powers on but no signal. We isolate the GPU, RAM, cable, or board before you replace parts.

Sudden frame drops, hitching, or stutters. Often thermals, drivers, storage, or RAM.
💙 Blue Screen / Random Crashes
Crash loops and reboots under load. We test drivers, RAM, and unstable overclocks.

Pump failure, air in the loop, or a leak. We service AIO and custom water cooling.
