Computer repairs Karrinyup with clear advice on the best option for your laptop, desktop, Wi-Fi or home-office problem.
Microsys helps Karrinyup customers with computers that will not start, run slowly, overheat, disconnect from Wi-Fi or display repeated errors. We remove malware, replace failed storage, upgrade ageing systems, configure new computers and reconnect printers, email and backup services.
Similar symptoms can have very different causes, so we diagnose before quoting major work. A slow laptop might need an SSD, but it might instead have unwanted software or a cooling problem. An unstable connection may be the computer, router or coverage. We test and explain the evidence before recommending the repair.
Onsite Karrinyup support is useful for Wi-Fi, printers, multiple devices and complete desk setups. Remote service is available for many software and account issues. Workshop assessment is best when a machine has physical damage, no power or a suspected failing drive.
Residential work is 0 + GST per hour and business work is 0 + GST per hour. Additional time is charged in 30-minute increments and no fix, no fee applies to eligible jobs.

If you're dealing with any of these, you're in the right place. Our Karrinyup technicians diagnose the true cause and give you a fixed price before any work begins.
A computer that won't power on, gets stuck on a black screen, or loops before reaching Windows usually comes down to a faulty power supply or charger, a loose or failed RAM module, a corrupted boot drive, or a deeper hardware fault on the motherboard. We test power delivery and each component in isolation, then check whether it's Windows failing to load or a genuine hardware fault, before quoting the fix.
Random reboots, Windows crashes and the blue screen of death (BSOD) are almost always a sign that something specific is wrong — outdated or conflicting drivers, failing RAM, an overheating CPU, or a corrupted system file. We read the crash logs and error codes Windows leaves behind and run hardware stress tests to track the fault to its actual cause, rather than reinstalling Windows and hoping it goes away.
A slow computer is rarely one single problem. Common causes include too many programs starting up with Windows, malware running in the background, a nearly full hard drive, insufficient RAM, or an ageing mechanical hard drive that's reached its limit. We check each systematically and recommend the fix that actually makes a difference — often an SSD upgrade or a proper clean-out rather than a full rebuild.
Clicking, grinding or loud fan noise inside a desktop or laptop is worth taking seriously. A clicking hard drive can mean it's failing and at risk of losing data. Loud fans and a hot case usually point to dust build-up, a failing fan, or dried-out thermal paste. We run hardware diagnostics on the drive and cooling system, and clean or repair what's needed before it causes further damage.
When a computer won't connect to Wi-Fi, or connects but keeps dropping out, the cause can sit anywhere from a faulty wireless adapter or outdated driver to a Windows networking glitch or a router problem. We test the adapter and drivers first, check Windows network settings, and rule out router or network issues so you know exactly what fixed it.
Constant pop-ups, fake virus warnings, a hijacked browser or a computer that's suddenly crawling are classic signs of infection. We remove viruses, spyware and ransomware safely through our Virus & Malware Removal service and lock your system down so it stays clean.
Tell us the symptoms and we'll give you a fast, honest assessment — no obligation.
From your first call to a fully working computer — clear, quick and completely stress-free.
We identify the problem and determine the likely cause, whether that means testing hardware, checking Windows logs, or running diagnostics in our workshop.
We explain the recommended repair and the expected cost before we proceed. You approve the price — there are no surprises added afterwards.
We complete the repair, with same-day service wherever practical, and test everything thoroughly before your computer comes back to you.
Every job is a little different, so Microsys offers two ways to get your computer fixed.
A Karrinyup onsite visit allows the technician to reproduce the fault with the router, printer and devices involved. That helps confirm the solution works across the complete setup.
You drop your computer off and we diagnose and repair it at our workshop. This is usually the better option for hardware jobs — hard drive and SSD replacements, motherboard faults, or anything needing specialist tools and a controlled environment.
Not sure which suits your situation? For some software issues, remote support may also be possible — call us and we'll recommend the right option based on what's gone wrong.

Computers rarely fail without warning. Catching problems early often means a cheaper, simpler fix — and a much lower chance of losing your data. If your computer is showing any of the following signs, it's worth getting it checked before a small issue becomes a major one.
Watch out for a machine that has become noticeably slower over a short period, frequent freezes or crashes, the dreaded blue screen, or a computer that randomly restarts on its own. Loud fan noise and a case that runs hot to the touch are classic signs of overheating. Unusual clicking or grinding noises from inside the case often point to a failing hard drive — a problem worth addressing urgently, before it takes your files with it.
A sudden flood of pop-ups, a browser homepage that keeps changing, or unfamiliar programs appearing are strong indicators of a virus or malware infection. Whatever the symptom, our technicians can quickly tell you what's going on and what it will cost to fix. For general online safety guidance while you wait for your appointment, the Australian Government's cyber.gov.au is a good independent resource.
Book a diagnosisIt's one of the most common questions we're asked — and our answer is always honest, never driven by a sale.
The good news is that many computers written off as "too old" can be brought back to life affordably. In a large number of cases, replacing a slow mechanical hard drive with a fast SSD and adding more memory transforms a sluggish machine into a fast, responsive one — often for under a few hundred dollars, a fraction of the price of a brand-new computer.
Repairing also keeps your familiar setup intact. No need to migrate everything, reinstall programs, or hunt down old passwords. Your files, your software and your settings stay exactly where you left them — just faster and more reliable.
That said, there are times when replacement genuinely is the smarter choice. If the cost of the repair approaches the value of the computer, or if critical components like the motherboard have failed on an older machine, we'll tell you straight. We would rather give you honest advice and earn your trust than sell you a repair that doesn't make sense.
When you bring your computer to Microsys, we assess it properly and lay out your options clearly, with the costs and trade-offs of each. You make the decision with all the facts in front of you, and never feel pressured.

A sample of verified reviews Perth customers have left us.
My laptop wouldn't start the morning of a big deadline. Microsys had it fixed and back to me the same afternoon. Lifesavers.
Honest, fast and friendly. They told me an upgrade would be cheaper than a new PC and they were right — it runs like new now.
Got rid of a nasty virus and set up backups so it won't happen again. Clear pricing and no jargon. Highly recommend.
