Nyctale is a Windows desktop diagnostic tool that scans your PC (hardware health, drivers, startup bloat, background processes) and tells you in plain language what's actually wrong — and whether it's worth fixing or replacing. Built for people who get told 'you need a new PC' by a repair shop and want a second opinion before spending money. Free to use, no subscription.

As an IT technician, I see a lot of users replacing hardware that just needed a driver update or a cleanup. A tool that distinguishes between software-fixable issues and actual hardware failure is genuinely useful. Does Nyctale provide a clear report that a non-technical user could bring to a repair shop? That would help bridge the gap between diagnosis and action.
Hi, maker here. I built Nyctale after watching people get told 'your PC is dead, buy a new one' at a repair shop when the real problem was a failing driver or a dying fan. It runs a real hardware/software diagnostic and explains the result in plain language, so you have a second opinion before spending money on a replacement or a repair. Happy to answer questions about what it actually checks.
Hi Fazier 👋 William here, creator of Nyctale Diag & Fix. Most "PC cleaner" tools sell you a magic button. In my experience the real causes are boring: a bloated startup, a nearly full disk, a fan full of dust. And sometimes the honest answer is "this is hardware, no software will fix it". So Nyctale gives you a verdict you can act on, and it's allowed to say "this isn't fixable by software". The pitch I keep coming back to: before replacing your PC, run the diagnostic. Two questions for you: Would you trust a tool that tells you "don't buy anything yet"? As a tech/IT person: what's the one thing you'd want in a report to show a customer? Free to start, runs locally. www.nyctale.fr
"Second opinion before you spend money" is the right pitch; most PC cleaners sell fear instead. Does the report split "fix it yourself" items from "needs a shop" items? A rough cost next to each finding (driver update: free, new fan: about $15) would make the repair-or-replace call obvious for non-technical people.
Love that it's willing to say "your hardware is fine, don't replace it". That's the opposite of most PC cleaners. One idea: a shareable one-page report I could show a repair shop or a family member, so the second opinion actually travels with me. Does the scan save a history so I can see if things get worse over time?
