A desktop or iMac is built to last longer than the parts inside it. Drives fail, fans wear out, graphics cards die, and operating systems slow down — but the machine itself can usually keep going. MiraFixit inspects the hardware, identifies what needs replacement or repair, and recommends whether the work is worth doing on the system you already own.
A desktop usually fails one part at a time. Identifying which one is the first step.
Common issues we work on:
– Powering issues
– No video signal, blank screen, or artifacts on display
– Random shutdowns, blue screen, kernel panics
– Slow performance, long boot times, freezing under load
– Loud fans, overheating, or sudden throttling
– Failed or failing hard drive or SSD
– Virus, malware, or unwanted software slowing the system
– iMac display issues, hinge, or stand failures
– Older iMacs running unsupported macOS and no longer receiving updates
Upgrades: Most desktops and iMacs respond well to a targeted upgrade rather than a full replacement. Common work includes SSD upgrades for faster boot and load times, RAM expansion for heavier workloads, and graphics card replacement for newer software or higher-resolution displays. For older iMacs, drive and memory upgrades often extend usable life by several years.
Repairs: When a part fails, we identify it, and replace it. Power supplies, fans, drives, GPUs, RAM, optical drives, and case-level components. iMac repairs include display assembly, LCD panel, internal fan, and drive replacement on the models that support it.
Custom Builds: If you’re building a desktop and need someone to assemble it correctly — or you want a system specified, sourced, and built around how you actually use it — we handle both. Bring your own parts, or have the build planned around a target use case and budget. The quote is explained before any parts are ordered.
A desktop that ran clean two years ago and crawls now usually has a clear cause. Dust packed into the fans. A drive nearing failure. Thermal paste that’s dried out. Background software piling up after every install. Sometimes the cause is one of those. Sometimes it’s all of them at once.
MiraFixit cleans the chassis, replaces thermal paste, tests storage health removes unwanted software, and checks temperatures under load. The goal is a system that behaves correctly — not just for a week, but consistently after the service is done.

Some failures live deeper than a part swap. A no-power desktop with a failed motherboard, an iMac with a damaged logic board, or a system with severe power-supply damage may need board-level diagnostics before any repair is possible.
If the issue is a failing or dead drive and the priority is the data on it, Data Recovery & Password Reset handles that work directly. The order matters: recovery first, then repair or replacement.
Drop off, schedule a pickup in Orange, Riverside, or Los Angeles County, or mail it in from anywhere else. We inspect, explain, and quote before any works begins.

Most major desktop brands — Dell, HP, Lenovo, ASUS, Acer, Microsoft — along with prebuilt gaming desktops and custom-built tower PCs.
On the Apple side, we work on iMac, iMac Pro, and Mac mini, including older Intel-era models still in service.
Often, yes. A drive swap to SSD and a RAM expansion can extend a five-to-eight-year-old iMac by several years. Whether it's worth the cost depends on the model, your workload, and what else is showing wear. We'll inspect and tell you honestly — including when a replacement is the better choice.
Usually, yes. Most power issues come down to the power supply, a loose connection, a failed component, or a board-level issue. We inspect, identify the cause, and explain what the repair would involve before any work begins.
Yes! We assemble desktops from parts you supply, or plan and source a build around a target use case and budget. The quote is explained before any parts are ordered.
The common causes are storage failure, thermal throttling from dust or dried paste, low memory under modern workloads, or background software accumulated over time. Often, it's more than one. We test for each and explain what's contributing.
Yes. We remove malware, clean up unwanted software, restore browser and system settings, and check for residual damage. If the system has been compromised heavily, a clean OS install with a data backup may be the better path — we'll explain the options.
Board-level diagnostics applies when the motherboard or power circuitry is damaged and a part swap won't solve it. Data recovery applies when the priority is the files on a failing drive. Both have dedicated pages explaining the process in greater detail, and we route the work there when the situation calls for it.
