Windows Troubleshooting Assistant
Choose what is happening, narrow down the symptom, and get a safe first-check plan with links to focused guides. This tool helps you choose the next investigation; it does not scan your PC or diagnose a failed component.
Your answers are processed in this browser; files, logs, and diagnostic output are not submitted for analysis. If you have accepted analytics, the site may record the selected symptom category and chosen option for aggregate tool-use measurement.
What is the main problem?
Start with the symptom that best matches what you see.
Record the exact error, when it began, what changed recently, and whether it repeats. Change one variable at a time and compare the same workload before and after. Avoid downloading unknown “driver updater” or repair utilities.
Frequently asked questions
Does the assistant diagnose my PC automatically?
No. It routes the symptom you choose to safe first checks and relevant guides. It does not scan your computer, inspect logs, or prove a hardware fault.
Does it upload my answers or computer data?
No. The choices and recommendations run in your browser. If you have accepted analytics cookies, the site may record tool-use events containing the selected symptom category and chosen option, not files, diagnostic logs, or device identifiers.
Should I reinstall Windows if the first check does not work?
Usually not as a first step. Record the exact symptom and error, protect important files, and follow the focused guide before trying destructive recovery steps.
What should I do if I suspect a failing drive or electrical damage?
Stop repeated power-on attempts if you hear unusual drive noises, smell burning, see liquid damage or a swollen battery, or suspect electrical damage. Protect important data and seek qualified repair help rather than opening a power supply or forcing a repair.
