Desktop PC repair, upgrades, and custom builds.

No power, no display, Windows trouble, random restarts, overheating, failed drive, slow performance, or an upgrade that needs to be planned correctly. Desktops are highly repairable and highly upgradeable. We isolate the failed part before recommending replacement.

Section 01 / Symptoms

What is the PC doing?

Desktop faults are usually isolatable to one component, because almost every part is separable and can be tested on its own.

SYM-01 Slow, high disk usage, or freezing Storage, memory, Windows, malware, heat, or hardware instability. SYM-02 No power Power supply, switch and front-panel wiring, motherboard, or shorted hardware. SYM-03 Fans spin, no display Memory, graphics, motherboard, CPU, or a startup and post issue. SYM-04 Random restart or shutdown Power supply, thermals, memory, graphics, or board-level instability. SYM-05 Runs hot or very loud Dust, cooler, fans, thermal compound, airflow, or load-related cooling limits. SYM-06 Will not boot or drive missing Drive health, Windows, boot configuration, storage controller, or hardware.

Section 02 / Diagnosis

Test parts separately before replacing the computer

Unlike a laptop, almost every part of a desktop is separable. That makes isolation straightforward: test in order and the machine tells you which part failed.

01

Power

Power supply output, board startup, and shorted hardware.

02

Post and hardware

Memory, graphics, CPU, motherboard, and minimum-configuration testing.

03

Storage and Windows

Drive health, startup, Windows, data, and performance.

04

Thermal and stability

Temperatures, fan and cooler function, load testing, and power stability.

Section 03 / Builds

Custom builds and upgrades

Built around what you actually do with it, and serviced afterward by the person who put it together.

Gaming builds Workstations Editing & rendering Home & office Small form factor Upgrades to existing PCs Storage & memory Cooling & airflow
Before you buy a new one

Before replacing an older PC, measure what is actually holding it back. A good SSD, more memory, or the right graphics card can make sense. Sometimes a new system is the better value. The recommendation should follow the workload and the numbers.

Section 05 / Pricing

What desktop work costs

The $40 diagnostic is credited toward an approved repair. Hardware replacement, upgrades, and custom builds are quoted by parts and labor. Motherboard-level repairs follow the published board-repair range when applicable.

$40

Diagnostic

Credited toward an approved repair. Covers the testing needed to identify the fault.

$150 to $350+

Motherboard repair

Component-level board work. Set by which stage failed and how far the damage spread.

Quoted per build

Custom builds and upgrades

Parts and labor quoted together, after compatibility and the intended improvement are confirmed.

Prices vary. For an accurate number, or a quote on a build, call or text.

Section 07 / Questions

Before you book

My PC is slow. Should I replace it?

Not automatically. We check storage, memory, CPU and GPU workload, Windows, and thermals first. Sometimes one inexpensive upgrade is the difference between a frustrating PC and a useful one.

Can you build or upgrade a gaming PC?

Yes. Builds and upgrades are planned around the games and workloads, the case, power supply, cooling, and compatibility, rather than just choosing the fastest individual part.

Can a desktop motherboard be repaired?

Some motherboard faults are very repairable. Failed power stages, damaged connectors and headers, capacitors, and physical board damage can sometimes be repaired instead of replacing the board.

The fans spin but I get no picture. What is that?

The machine has power but is not completing its startup checks. It is almost always memory, graphics, or the board, and minimum-configuration testing isolates which.

My PC got very loud over the last year. Is something failing?

Usually dust, dried thermal compound, or a fan on its way out. All three make the machine run hotter and louder, and all three are straightforward to service.

Book

Bring in the tower, and the power adapter or unusual accessories if the problem depends on them.

We will isolate the failed component, quote the repair or upgrade, and test the system under real load before pickup. $40 diagnostic credited toward approved repair.
