This is probably the most common question I get at the end of a diagnostic call. The computer is slow, unreliable, or driving someone crazy — and they want to know if fixing it makes sense or if it's time to buy new. Here's the honest framework I use.
The short version: it depends almost entirely on whether the problem is in the software layer or the hardware layer. Once you know that, the decision usually becomes obvious.
A clean Windows install removes everything in the software layer and starts fresh. It wipes out:
If your computer was fast two years ago and gradually got slower — this is almost certainly your problem. Software layer degradation is normal. A reinstall is the reset button.
This is where it's easy to make an expensive mistake. A fresh Windows installation does nothing for:
Here's why this matters: I've had customers pay someone to reinstall Windows on a machine with a failing hard drive. The reinstall went fine. Two weeks later, the drive died and took everything with it. The reinstall treated the symptom — slow computer — not the cause. The diagnostic step that should happen first is checking the hardware.
A Windows reinstall from Hardwired IT runs $150–200 at your Ottawa home. That includes backing up all your files to external storage before we start, the clean installation, setting up your drivers and essential software, and restoring your files. You're never without your machine overnight.
A new mid-range laptop starts at $700–1,100. A budget laptop starts at $450–600 — and you'll feel the compromise in performance within a year. The reinstall pays for itself if the machine runs well for even another 18 months.
Where it stops making sense: if reinstall costs $200 and a new machine is $700, but the old machine also needs an SSD upgrade ($200) and a battery replacement ($150), you're now at $550 going into a machine with an uncertain future. That's when I'll tell you the replacement conversation is worth having.
Windows 10 and 11 have a built-in "Reset this PC" option. It sounds like a reinstall, and it can help — but it's not the same thing. A Windows Reset still uses the existing Windows installation as a base. It removes some clutter but leaves drivers intact and doesn't clear all residual problems the way a truly fresh install does. If a reset fixed it, great. If the machine is still sluggish after a reset, a full reinstall is the next step.
With a properly done reinstall: nothing bad happens to your files. Before I touch anything, I back up everything you want to keep — documents, photos, downloads, desktop files, browser bookmarks — to an external drive. After the fresh Windows installation, your files come back. You get a clean operating system with your personal files restored.
The programs you had installed will need to be reinstalled. Most people have 5–10 programs they actually use, and reinstalling them on a clean machine takes about 20 minutes. I'll walk you through it or handle it during the appointment.
At your home: 2–3 hours for most machines. Older laptops with slower drives take longer; modern machines with SSDs go faster. I stay until it's done and you can see it's working before I leave.

Not with a properly performed reinstall. A technician backs up all your files to external storage before touching anything, then restores them after the fresh install. You get Windows starting clean, with your documents, photos, and personal files intact — without the bloatware, malware, and corruption that was making it slow.
A reinstall fixes software-layer problems: slow startup from too many programs, malware that removal tools couldn't clear, corrupted Windows files causing crashes, a system that's accumulated years of junk. It does not fix hardware failures — a failing hard drive, bad RAM, or overheating will cause the same problems on a fresh Windows installation.
A Windows reinstall from Hardwired IT runs roughly $150–200 at your Ottawa home, including data backup, fresh installation, driver setup, and restoring your files. It's done on-site so you're never without your machine overnight. No fix, no fee.
