Desktop computers present a unique mix of repair challenges: far more accessible for component swaps than laptops, but with a broader surface area for faults across power supplies, motherboards, GPUs, RAM sticks, and storage drives. At Cybrix Electronics, we repair desktop PCs of all configurations — from budget office towers and all-in-ones through to custom gaming builds and professional workstations. We diagnose the real cause rather than just replacing parts speculatively.
Many of the computers that come through our door aren't actually broken — they're just slow. Years of accumulated software, startup entries, malware, and a clogged mechanical hard drive can make a perfectly functional machine feel unusable. In many cases, a combination of virus removal, SSD upgrade, and a clean Windows reinstall transforms the experience entirely. We'll tell you honestly which category your computer falls into rather than overselling you on hardware repairs you don't need.
For hardware faults — power supplies that fail to POST, GPUs with artefacting, RAM errors causing blue screens, or capacitor issues on older boards — we carry out proper fault isolation and carry stock of the most common replacement components. We also build custom PCs to order and provide upgrade consultations for people who want to get more life out of an existing machine.
From everyday wear to complex hardware faults — here are the issues we deal with most often.
BSODs can stem from driver conflicts, failing RAM, a dying hard drive, overheating, or Windows corruption. We read the crash dumps and identify the real culprit.
A computer that shows nothing on screen, beeps on startup, or gets stuck at the motherboard logo has a hardware fault we'll systematically isolate.
Ransomware, browser hijackers, crypto miners and spyware — we remove all classes of malware thoroughly and close the vulnerabilities that allowed entry.
A mechanical hard drive, too little RAM, background junk, or a fragmented Windows install can cripple performance. We identify the bottleneck and address it properly.
PSUs fail gradually or suddenly — causing random shutdowns, no-power situations, or instability under load. We test and replace PSUs across all form factors.
Whether it's a dead GPU, a failed display port, loose video cable, or an iGPU fault, we trace display signal issues methodically.
Dust-clogged heatsinks, dried thermal compound, and failed case fans cause overheating and loud operation. A proper service clean makes a noticeable difference.
Clicking, grinding, or ticking from a hard drive is a precursor to failure. We back up your data urgently and replace the drive before full failure occurs.
We carry parts and have experience with the following models — and many more not listed here.
From booking to pickup — a straightforward, transparent process every time.
Book online and describe the symptoms. For tower PCs, you'll bring in the tower unit (monitor not usually needed). For all-in-ones, bring the whole unit.
We run POST diagnostics, boot tests, hardware stress tests, SMART drive checks, RAM tests and malware scans. This gives us a complete picture within 30–45 minutes.
You receive a clear breakdown of what's wrong and what fixing it will cost. We'll also flag any secondary issues (like a drive nearing failure) that are worth addressing while we're in there.
Hardware repairs, software fixes, virus removal, or upgrades are carried out by our experienced technicians. For complex motherboard faults, we'll agree a realistic timeframe with you.
Pick up your repaired PC knowing it's been fully tested — boot cycle, load testing, temperature monitoring, and all connected peripherals verified working.
Hundreds of satisfied customers trust Cybrix Electronics with their devices. Here\'s what makes us different.
We don't guess. We use POST codes, crash dump analysis, SMART data and hardware stress tests to identify the actual fault before recommending any repair.
We'll tell you whether your machine is worth upgrading or whether a fresh build makes more financial sense for your needs.
We stock PSUs, RAM, SSDs, thermal paste, and common motherboard components — enabling fast same-day or next-day turnaround for most common repairs.
All hardware repairs and component replacements carry our standard 90-day parts and labour warranty.
Book online in under 2 minutes. No fix, no fee — guaranteed.
Virus removal and software repairs start from $75, including a post-removal security audit and recommendations. SSD upgrades (with data migration) start from $99. RAM upgrades start from $49 (plus cost of RAM). Power supply replacements start from $89 including the replacement PSU for standard ATX form factors. Full system cleans (dust removal, thermal repaste, fan service) are $65.
Motherboard-level repairs are quoted individually after diagnosis. We always confirm pricing before starting any work, and the diagnostic itself is always free.
