My computer is slow and I don't understand why

A computer that gradually slows down always has a precise cause, software-related in the vast majority of cases — it's never a random aging effect.

The scenario is almost always the same. A year ago, the computer started up in a few seconds. Today, opening a plain browser window takes an absurd amount of time. Nothing unusual was installed, nothing visibly "broke" — and yet everything is slower.

It's one of the most frustrating situations in computing: a real, measurable problem that's completely invisible. No error message. No obvious starting point. And the most natural temptation — assuming the computer is just "old" and needs replacing — is rarely the right answer.

Why does my PC slow down for no apparent reason?

A PC doesn't lose speed over time the way a battery wears out. Every slowdown has an identifiable cause, and in the vast majority of cases, that cause is software, not hardware. The usual suspects:

• A program set to launch automatically with Windows that keeps running in the background forever.
• A browser with dozens of open tabs saturating memory.
• Windows' "fast startup", which can prevent certain stuck states from resolving even after a restart.
• A hard drive (not an SSD) nearing the end of its life, slowing down before failing completely.

The problem is that none of these causes are visible to the naked eye. Windows Task Manager gives you a snapshot, but it doesn't tell you what's happening over time, or why a given program is consuming so much.

Why does guessing cost more than checking?

Many people try a first instinct — uninstalling a random program, emptying the recycle bin, restarting a few times — without knowing whether it actually addresses the cause. The result: the problem comes back, and the conclusion becomes "I need a new PC." That's often €300 to €800 spent on a problem that could have been fixed in minutes.

That's exactly what a diagnostic is for: replacing guesswork with a precise answer. Nyctale was built for this — it analyzes a computer and explains, in plain language, what's actually slowing it down, no technical jargon, and it never changes anything without your consent.
