How it works

How to use the result

Treat the result as a shortlist, not a verdict. Run the first check before you change anything, change one thing at a time, and give each change time before judging. If the first cause is ruled out, move to the next one.

Common questions

How does this tool decide?

Each answer adds weight to the causes it points to, and the causes with the most weight are listed first. There is no AI and no guessing: the rules are fixed and match our troubleshooting guides.

Does it need my ad account?

No. It only uses your answers, runs in your browser, and sends nothing to us.

What if two causes look equally likely?

Check them in the order listed, starting with the cheapest check. Change one thing at a time so you can tell what worked.
