Computer Repair
in Davis, CA

Diagnostics start at $40. More complex issues may require additional testing, but we confirm the diagnostic fee with you before proceeding. The full diagnostic fee is credited toward an approved repair. You receive a clear explanation of the reported problem, the issue identified, and whether it was resolved.

The cost depends on the fault, testing required, replacement parts, and the repair you approve. A no-display problem, overheating PC, failed drive, and damaged Windows installation require different work, so NorthCore diagnoses the computer before giving you a repair recommendation. We explain the expected price and obtain approval before replacing parts or expanding the scope.

Yes. NorthCore repairs gaming PCs, custom-built computers, and major-brand prebuilt desktops in Davis, California. We diagnose no-display problems, failed startup, crashes, overheating, noisy cooling, poor performance, and upgrades that did not go as planned. Share the current specifications and any recent hardware changes when you contact us.

Yes. We first separate no power, failed POST, no display, and Windows boot failures because each points to a different test path. The cause may involve power delivery, memory, graphics, storage, motherboard or firmware behavior, damaged Windows files, encryption, drivers, or boot configuration. We test the likely hardware and software causes and explain the findings before recommending parts or repair work.

A PC that powers on without a display can have a monitor or cable problem, improperly seated memory, graphics-card failure, processor or motherboard trouble, insufficient power, or a firmware setting that prevents startup. We test the system methodically instead of assuming the GPU is responsible, then explain what the evidence supports before recommending replacement parts.

Random crashes and restarts can come from unstable RAM, overheating, a failing SSD or hard drive, power-supply trouble, graphics hardware, damaged Windows files, drivers, or incorrect system settings. Because these faults can produce similar symptoms, we reproduce the problem where possible, review Windows error history, and test the most likely causes before recommending a repair.

Yes. Slow performance may be caused by a failing drive, limited memory, overheating, unwanted startup software, malware, Windows problems, or hardware that no longer fits the workload. We identify the bottleneck before recommending an SSD, additional RAM, cleanup, Windows repair, or replacement so you do not pay for an upgrade that will not solve the real problem.

Yes. We inspect CPU and GPU temperatures, airflow, dust buildup, fan operation, cooler mounting, thermal material, and behavior under load. The appropriate overheating repair may involve cleaning, correcting a mounting problem, replacing a failed fan or cooler, improving case airflow, or addressing the workload or settings causing excessive heat.

Yes. Tell us which components changed, what the computer did before the work, and what happens now. Bring the original screws, brackets, modular power cables, adapters, and removed parts that may be relevant. We determine whether the job is installation, compatibility troubleshooting, or diagnosis of a separate hardware fault and quote the appropriate work.

No. We explain the diagnosis, recommended repair, and expected price before replacing components or expanding the work. If testing reveals a different fault, we pause and contact you so you can decide how to proceed. Customer approval applies to the repair scope, parts, and additional diagnostic work.

Computer-repair turnaround depends on whether the fault can be reproduced, the testing required, and replacement-part availability. Common repairs and upgrades may be completed quickly once the cause and parts are confirmed. Intermittent crashes, data-sensitive work, or special-order components can take longer. NorthCore provides a realistic timeframe after reviewing the computer.

That depends on the complete repair cost, the computer's age and condition, its performance for your needs, replacement cost, and the value of reusable parts. We will tell you when a repair is difficult to justify. If fixing the PC does not make sense, we can discuss a focused upgrade, replacement, custom build, or trade-in inquiry instead.

If you are bringing the desktop in, include any power adapter or accessory directly involved in the problem. Also share photos of error messages, blue-screen stop codes, notes about motherboard diagnostic lights, parts involved in a recent upgrade, and the original brackets or modular power cables from unfinished work. If transport is difficult, ask about repair pickup and return delivery when booking. You do not need to diagnose the fault yourself.

Yes, repair pickup and return delivery can be arranged when available. You can also bring your device in by appointment. Tell us your location and preferred timing when you contact us, and we will confirm coverage, availability, and any transport fee before scheduling. This can help students without transportation, families, or anyone who cannot easily make the trip.

NorthCore provides a 30-day workmanship warranty on eligible labor performed within the agreed scope. Parts, manufacturer warranties, customer-supplied components, unrelated failures, new damage, malware reinfection, and customer changes are handled separately. Applicable coverage is explained at handoff.
