Made by someone who fixes PCs for a living
I’m Tony Mazy. After 25+ years in IT, I got tired of manually reading log files on troubled computers for hours. So I built this tool to do the tedious part for me — and now I use it every day for fast troubleshooting. It’s the same engine you get here.

Why it exists
Windows tells you what happened.
We tell you what to do about it.
Your PC already records why it crashed, stalled or rebooted. The problem is that the evidence is spread across event logs, driver tables and crash dumps that were written for engineers. DiagnoseMyPc reads all of it in one pass and hands back a plain-English answer you can act on.
Troubleshooting on your own
- Scrolling Event Viewer line by line, hoping an event ID means something
- Forum threads written for a different build of Windows, years ago
- Trying fixes one at a time and hoping nothing else breaks
- Booking a repair shop and handing over the machine for days
With DiagnoseMyPc
- Describe the problem in plain English — no jargon or tools required
- 50+ automated checks across hardware, drivers, security, updates and performance
- Findings ranked critical → warning → info, each tied to the evidence it came from
- Exact steps and copy-paste commands, with a restore point created before they run
One pass instead of an evening
A single scan replaces opening Event Viewer, Device Manager, Reliability Monitor, Disk Management and a dozen command prompts by hand.
Evidence, not guesswork
Every finding names the log entry, driver or service behind it, so you can check the reasoning before you change a single setting.
Safe to act on
Generated fix scripts create a Windows restore point first and finish with instructions for rolling the change back.

Want the deepest report? Run the full scan
The free Windows scanner reads your logs, drivers and hardware health in one pass. Here's exactly what to expect.
Download the App
Get the lightweight DiagnoseMyPc installer onto your computer in under a minute.
Visit diagnosemypc.com
Open your browser and go to diagnosemypc.com. Type or paste a short description of the issue you’re experiencing into the text box on the homepage.
Click "Diagnose My PC Free"
Press the main call-to-action button to begin the download.
Installer downloads (430 KB)
Your browser will download DiagnoseMyPc-Setup-v1.4.0.exe. It’s only about 430 KB — smaller than most photos.
If your browser shows a warning
Most downloads now complete without any prompt. Occasionally Chrome still shows a “Suspicious download blocked” message — this is a false positive on a signed installer. Click the › arrow next to the warning (or press Ctrl + J to open Downloads) and choose "Keep".
Download complete
The installer is now in your Downloads folder, ready to run.
Install, Scan & Review
Run the installer, let the app scan your system, and review the AI-generated report with suggested fixes.
Double-click the installer
Open DiagnoseMyPc-Setup-v1.4.0.exe from your Downloads folder (or click it in the browser’s download bar).
Approve the UAC prompt
Windows will ask for administrator permission. Click "Yes" — the scan needs elevated access to read system diagnostics.
Walk through the setup wizard
A plain setup window appears. Click "Next", then "Install". No custom options are needed.
Installation completes quickly
Because the installer is so small, setup finishes in a few seconds.
The app scans your system
DiagnoseMyPc launches automatically and runs a full system scan. This usually takes under a minute.
Review your AI report
When the scan finishes you’ll see an AI-generated report listing issues by severity, along with recommended fixes you can apply.
Exactly what we look at — and what we never touch
A diagnostic tool asks you to trust it with your computer, so here is the full list. No vague reassurances: this is what leaves your PC, what never does, and what happens to it afterwards.
What we collect
What you type
Your description of the problem, in your own words.
Anything you choose to paste in
Screenshots of an error, or output you copied from Command Prompt or PowerShell.
The optional system scan ZIP
Windows event logs, drivers and problem devices, services and startup items, installed updates and software, hardware and GPU details, crash-dump summaries, network configuration, firewall / Defender / BitLocker status, scheduled tasks and reliability history.
Your account email and past reports
So you can sign back in and reopen a diagnosis you already ran.
What we never collect
No personal files
Documents, photos and desktop contents are never opened, read or uploaded.
No passwords or Wi-Fi keys
The scan lists the names of saved networks only. It never requests stored keys.
No browsing history or cookies
Browser data is not part of any diagnostic category we collect.
No remote access
Nothing controls your PC or stays running in the background. The scan writes a ZIP file and exits.
No card details
Payments are handled entirely by Stripe. We never see or store a card number.
Never sold, never used for AI training
Your diagnostic data is used to answer your question and nothing else.
Sent over an encrypted connection
Nothing is uploaded until you pick a file or press analyze.
Analyzed once
Processing happens through our AI provider, which does not store your data or train on it.
Upload deleted
The uploaded file is deleted as soon as the analysis finishes. Only the report stays — in your account, visible only to you.
Worth knowing before you upload
Windows diagnostic logs are plain text, so they can include your Windows account name and local network details wherever those appear inside a file path or a log entry. The scan saves the ZIP to your desktop first — you can open it and read every file before you decide to upload anything.
Currently available for Windows 10, 11 & Windows Server
Supports Server 2012, 2016, 2019, 2022, 2025 · Mac & Linux coming soon
Everything you need to know
Answers to the most common questions before you run your first scan.
Is DiagnoseMyPc free to use?
Yes. You can run a free AI diagnosis with no account, and a free account gives you 5 full scans every month. If you want the one-click fix scripts and detailed step-by-step guides, you can grab a one-time $4.99 Fix Pass (7 days of full access, no subscription) or upgrade to Pro.
Is it safe, and what happens to my data?
It's safe. The analyzer reads only the diagnostic text, screenshots, or log files you choose to share — it does not make changes to your PC on its own. Any fix scripts are shown to you first so you stay in full control of what runs on your computer.
Do I need to install anything?
No. You can paste an error message, upload a screenshot, or paste command output and get an instant diagnosis right in your browser. For a deeper analysis, there's an optional lightweight collector that gathers your Windows logs into a single file you can upload.
What kinds of problems can it diagnose?
Slow performance, blue screen (BSOD) errors, random crashes and freezes, high CPU or RAM usage, driver conflicts, startup and boot problems, and security or malware warning signs across Windows 10 and 11.
What do I get with the $4.99 Fix Pass?
The Fix Pass is a one-time $4.99 payment that unlocks 7 days of full Pro access — including one-click PowerShell fix scripts, detailed resolution guides, and priority processing. It's not a subscription and does not renew.
What's included in Pro?
Pro gives you 30 scans per month, one-click PowerShell fix scripts, detailed step-by-step resolution guides with commands, links to official documentation, priority processing, and a saved analysis history dashboard.
Is there a money-back guarantee?
Yes. Every paid plan and the Fix Pass are backed by a 30-day money-back guarantee. If it doesn't help you, email [email protected] within 30 days for a full refund.
How is this different from just asking a regular AI chatbot?
It's purpose-built for Windows troubleshooting. Instead of a wall of generic text, you get issues ranked by severity, findings linked to the specific problem you describe, and ready-to-run fix scripts — all based on your actual system data rather than guesswork.
