On my Windows PC: Troubleshooter That Finds "Nothing Wrong"

“Nothing found” just means the troubleshooter’s checks didn’t identify a problem—it doesn’t mean your PC is working correctly.

A useful next step is Reliability Monitor. Search Start for View reliability history, then check the day and time the problem occurred. Click any red error marks and open View technical details. Repeated failures involving the same app or component can give you something specific to investigate.

If this started recently, compare that date with Settings > Windows Update > Update history. Timing is a clue, though not proof that an update caused it.

What exactly is happening—freezing, crashing, slow performance, or a connection problem? That detail matters more than running a long list of repair commands. Include any error message and when it happens; then it’s possible to choose a relevant test rather than updating or reinstalling things at random.
