Signs Your Computer Needs a Speed Fix

Computers slow down gradually, so it is easy to accept the frustration as normal. It is not. These are the signs Perth locals bring their PCs in for, and every one of them is fixable.

Boot Takes 5+ Minutes
Waiting for Windows to load long after you press the power button. Often caused by a dying hard drive, too many startup programs, or both at once.
Freezes and Locks Up
The mouse stops moving, programs stop responding and you sit there waiting. Can be RAM issues, overheating, a failing drive, or malware consuming all available resources.
Fans Running at Full Speed
The PC sounds like it is about to take off even when you are doing nothing intensive. Usually a sign of dust-blocked cooling, causing the CPU to overheat and throttle its performance.
Browser Crawls and Lags
Web pages take forever to load, tabs freeze, and scrolling is jerky. Can be a RAM shortage, malware running in the background, or a hard drive that cannot keep up.
PC Gets Worse Over Time
A PC that was fast three years ago and is now unbearably slow. Years of software installs, background processes, and startup entries accumulate into a system choking on its own clutter.
Slow and Unresponsive After Virus
Had a virus recently, ran an antivirus tool, but the PC is still sluggish? Many infections leave behind damaged system files or hidden processes that continue to drag performance long after the initial removal.
Root Causes

Why Is Your Computer So Slow? The Real Reasons.

Most slow PC problems have a specific, diagnosable cause. We have repaired hundreds of slow computers across Perth's southern suburbs and the same culprits come up again and again. Here is what we look for when your machine comes in.

01
Failing or Slow Hard Drive
Mechanical hard drives slow dramatically as they age. Bad sectors cause the drive to retry reads repeatedly, grinding performance to a halt. This is the single most common cause of a genuinely slow PC in older machines. An SSD upgrade solves it instantly and permanently.
02
Startup Program Overload
Every program you install wants to run at startup. After years of installs, dozens of applications are fighting for CPU and RAM the moment Windows loads. The result is a machine that crawls for the first 10 to 20 minutes every time you turn it on. We strip this back to what actually needs to run.
03
Overheating and Thermal Throttling
Processors are designed to reduce their clock speed automatically when they get too hot. If dust has blocked the heatsink or the thermal paste has dried out, the CPU runs hot constantly and throttles itself to avoid damage. The result is a PC that runs at a fraction of its actual capability. A proper thermal clean and repaste fixes it completely.
04
Malware and Background Infections
Adware, cryptominers, and spyware all run hidden processes that consume CPU, RAM, and internet bandwidth. Many people scan with a basic antivirus, get told the PC is clean, and still have hidden processes running. We use professional-grade tools that go deeper than consumer antivirus software to find and remove what is actually causing the drain.
05
Insufficient RAM
If your PC has 4GB of RAM and you are running Windows 11 with a browser, Office, and a few background apps open, the system is constantly swapping data to the hard drive to compensate. This is called thrashing, and it is brutally slow. Upgrading RAM is one of the most cost-effective speed improvements available on older systems.
06
Corrupted or Outdated Drivers
Corrupt or severely outdated drivers cause performance issues, freezing, and instability that mimic hardware problems. Particularly common after Windows updates that break compatibility with older drivers. We check every driver on the system and update anything that is causing issues.
07
Years of Software and Registry Clutter
Uninstalled programs leave behind folders, registry entries, scheduled tasks, and background services that continue to run and consume resources. After five or more years of normal use a Windows installation accumulates enormous amounts of this clutter. A thorough clean can recover significant performance without needing to reinstall Windows.
08
Windows Update Problems
Windows Update running out of control, stuck in a loop, or repeatedly failing can consume CPU and disk resources for hours without the user realising. A botched update can also leave Windows in a degraded state that causes ongoing slowness. We check update status as part of every diagnostic.
Not sure which one is causing your slowdown? That is exactly what our diagnostic is for. We test your machine systematically and tell you precisely what is wrong before we fix anything. You get a straight answer, not guesswork.
Real Results

What a Proper Fix Actually Looks Like

Numbers tell the story better than words. Here are typical before-and-after results from slow PC repairs we have completed for Perth customers, depending on the root cause and the fix applied.

Before — Slow HDD Machine
4–6 min
Boot time from power button to usable desktop. Programs take 30–90 seconds to open. Browser lags on every page load.
After — SSD Upgrade + Tune-Up
<18 sec
Boot time from power button to usable desktop. Programs open instantly. Browser snappy and responsive. Same hardware, completely different experience.
Before — Overheating Laptop
45°C idle
CPU temperature at idle due to dust-blocked heatsink. Throttles to 30% of rated speed under any load. Fan constantly at maximum.
After — Thermal Clean + Repaste
28°C idle
CPU running at full rated speed. Fan quiet at idle and workload. Performance benchmarks matching manufacturer specifications again.
We benchmark before and after every repair. You get a written speed comparison so you can see exactly how much improvement was achieved. Not a feeling — actual numbers.
Our Process

How We Fix a Slow PC. Step by Step.

We do not just run a clean-up tool and hand it back. Every slow PC repair at FixMyPC Perth starts with a proper diagnosis so we understand what is actually causing the problem. Then we fix it. Then we prove it is fixed with a benchmark.

Full System Diagnostic
Before we do anything, we run a structured diagnostic across every layer of the system. Hard drive health test, RAM stress test, CPU temperature and throttle check, boot time benchmark, startup program audit, malware scan, driver integrity check, and Windows health scan. We document everything we find so you know exactly what the machine is dealing with. This takes approximately 30 to 45 minutes and nothing is assumed — we test it.
Honest Report and Quote Before Any Work
After the diagnostic we give you a clear written summary of what we found and what is causing the slowdown. We explain the options, what each fix involves, and give you a firm price before we start. You decide what you want done. We never proceed with repairs without your explicit approval and we never pad the bill with unnecessary extras.
Startup and Background Process Optimisation
We audit and clean the startup sequence, removing or disabling every program and service that has no business loading at boot. This alone often reduces boot times by 60 to 80 percent on machines that have been in use for several years. We are careful to distinguish between programs that are safe to disable and ones that need to run — we do not just disable everything.
Deep Malware Scan and Removal
We run professional-grade malware scanning tools — not just Windows Defender — to find adware, cryptominers, spyware, and residual infection files that consumer tools commonly miss. If we find anything, we remove it completely and check that no system files were damaged in the process. If the damage is extensive we will advise on whether a Windows reinstall is the cleaner long-term solution.
Full System Clean — Thermal and Software
On the software side, we remove temporary files, browser cache, Windows junk folders, leftover installer files, and unnecessary scheduled tasks. On the hardware side, we open the machine and clean dust from the heatsink, fans, and vents using compressed air. If thermal paste has dried out — common after four or more years — we remove the old paste and apply a fresh application. Proper cooling is essential for sustained performance.
Driver and Windows Update Check
We check every driver on the system for corruption or outdated versions that could be causing performance or stability issues. GPU drivers, chipset, audio, network, and any other hardware-specific drivers are checked and updated where needed. We also check Windows Update status and resolve any failed or stuck updates that are consuming background resources.
SSD Upgrade If Recommended
If your hard drive is identified as a primary bottleneck — which is very common in machines more than four years old — we will have discussed this at the quoting stage. SSD upgrades are done in the same visit. We clone your existing drive to the SSD so Windows, all your files, and all your programs transfer across without loss. You do not start from scratch. From $65 labour plus the cost of the drive.
Before-and-After Benchmark Report
Once all work is complete we run the same benchmarks we ran at intake — boot time, drive read and write speeds, CPU performance under load, and RAM throughput. You receive a written comparison showing exactly what changed. We do this because we want you to see the improvement in hard numbers, not just feel it. It also gives you documentation of the work done.

Honest Advice

Tune-Up, Upgrade, or Reinstall — What Does Your PC Actually Need?

Not every slow PC needs the same fix. We will always tell you what your specific machine actually needs — not whatever costs the most. Here is a plain English guide to the options and when each one makes sense.

A tune-up alone ($89) is usually the right starting point when the PC is relatively recent — three to five years old — and the slowdown has crept up gradually over time. Startup bloat, software clutter, a basic malware clean, and a thermal dust out will often recover most of the lost performance without any hardware changes. If the diagnostic reveals the drive and RAM are healthy, this is likely all that is needed.

A tune-up plus SSD upgrade ($89 + from $65 labour) is the most transformative combination available for machines that are still solid hardware but are running on an old mechanical hard drive. The difference is not subtle — it is the difference between a machine that takes five minutes to boot and one that boots in under twenty seconds. We clone your existing drive so nothing is lost. This combination typically costs less than $200 total and extends the usable life of the machine by several years.

A tune-up plus RAM upgrade is the right call when the diagnostic shows the machine is regularly running out of physical memory and resorting to virtual memory on the drive. Very common on machines that shipped with 4GB of RAM that are now running Windows 11 and a modern browser. Adding RAM is inexpensive and eliminates the constant thrashing that makes these machines feel unresponsive under normal workloads.

A Windows reinstall ($120) becomes the better option when the slowdown is caused by deep Windows corruption, a severe malware infection that has damaged system files, or a machine that has accumulated so much clutter over many years that a targeted clean would take longer than starting fresh. We will recommend this honestly when it applies and combine the pricing where services overlap.

If the hardware is genuinely too old to be worth repairing, we will tell you that too. We would rather give you an honest assessment and lose the job than take $200 to repair a machine that will frustrate you again in three months. We see machines every week where the honest recommendation is replacement, and we say so.

Real Perth Customers

What Our Customers Say

Perth locals who came in with slow, sluggish, frustrating computers and left with machines that feel new again.

★★★★★

My laptop was taking nearly 8 minutes to start up every morning. Ali found it was a combination of a dusty heatsink and about 40 things loading at startup. Got it back the same afternoon and it boots in under a minute now. Wish I had done it years ago.

Sandra M. — Willetton
★★★★★

Thought I needed a new computer because mine was so slow. Turns out it just needed an SSD and a cleanup. $149 later and it is faster than when I bought it. Genuinely could not believe the difference. Should have gone here first instead of nearly spending $1200 on a new one.

David K. — Thornlie
★★★★★

PC was running terribly after I got a virus. Ran my antivirus and it said all clear but it was still slow as anything. Took it to FixMyPC and they found several things my antivirus had missed entirely. Fully sorted now and they explained exactly what they found.

Rachel T. — Gosnells
★★★★★

Really appreciated that they gave me a report showing what was wrong before they started. No upselling, just a clear explanation and a fair price. The before-and-after benchmark they gave me showed a 340% improvement in boot time. Very happy.

Common Questions

Frequently Asked Questions About Slow PC Repair

The most common reasons we see in Perth are a failing or aging mechanical hard drive, too many programs loading at startup, malware running hidden background processes, dust build-up causing the CPU to overheat and reduce its speed, insufficient RAM being supplemented by slow virtual memory, corrupted or outdated drivers, and years of software clutter accumulating in Windows. The frustrating truth is that it is often a combination of several of these at once. A proper diagnostic is the only way to know for certain which ones are causing your specific slowdown.
Our standard slow PC tune-up is $89 including GST. This covers the full diagnostic, startup optimisation, malware scan and removal, thermal inspection and dust clean, driver check, Windows health check, and a before-and-after benchmark report. If additional work is needed — like an SSD upgrade or a Windows reinstall — we quote separately before proceeding. You never pay for more than what your machine actually needs.
A standard tune-up typically takes 2 to 4 hours. If additional work like an SSD upgrade or Windows reinstall is being done alongside it, allow 3 to 6 hours. Most customers drop off in the morning and collect the same afternoon. We will give you a realistic time estimate when you arrive so you can plan your day.
In the majority of cases, repairing and upgrading an existing PC delivers far better value than buying new — particularly when the hardware itself is sound. A tune-up combined with an SSD upgrade for under $200 can give a five-year-old machine a second life that lasts another three to five years. We will give you an honest assessment when you drop off. If the machine is genuinely past its useful life, we will say so. We would rather tell you the truth and lose the job than take your money on repairs that will not last.
If your PC has an old mechanical hard drive, upgrading to an SSD is the single most impactful speed improvement you can make. Boot times typically drop from 3 to 6 minutes down to under 20 seconds. Programs open almost instantly. The PC feels completely transformed. We can do an SSD upgrade in the same visit as your tune-up, with all your data cloned across so nothing is lost. SSD upgrades start from $65 labour plus the cost of the drive, which we can source for you.
Yes. Malware and adware are among the most common causes of sudden or worsening slowdowns. Cryptominers in particular are designed to run hidden processes that use your CPU and memory at full capacity. Many infections also survive basic antivirus scans because the malware itself disables or hides from the tools most people use. Our slow PC service includes a deep malware scan using professional tools. If we find an infection we will explain what it is and remove it completely before moving on.
A slow and unresponsive PC can come from either software or hardware, and distinguishing between the two is exactly what our diagnostic process does. On the software side, startup bloat, malware, corrupt drivers, and Windows system file damage are common culprits. On the hardware side, a failing hard drive, overheating CPU, insufficient RAM, or failing capacitors on the motherboard can all cause sluggish or unresponsive behaviour. We test both systematically so we find the real cause rather than guessing.
Yes. We repair slow laptops and slow desktop PCs from all brands including Dell, HP, Lenovo, ASUS, Acer, MSI, Toshiba, Samsung and custom-built systems. The diagnostic and tune-up process covers both, and the pricing is the same regardless of brand or form factor.
The diagnostic tells us. A tune-up is usually sufficient when the hardware is in good condition and the slowness is caused by software clutter, malware, or startup overload. A Windows reinstall makes more sense when the slow performance is driven by deep Windows system file corruption, a severe malware infection that has damaged core Windows components, or a machine so loaded with years of junk that a clean start is faster and more thorough than piecemeal cleaning. We will tell you honestly which applies to your situation and explain why before you commit to either.
