- Reload the tab. If only one site crashes, the problem is that page, not the whole computer.
- Update Chrome at
chrome://settings/help. - Open a private window. If the site survives there, turn extensions off at
chrome://extensionsuntil you find the one that kills the tab. - If many tabs crash, turn off hardware acceleration in Settings, System, and restart Chrome.
- Clear data for that site only, not the whole profile, under Settings, Privacy, Cookies and other site data.
Do not use a page that promises to repair Chrome with a download. The official update is at chrome://settings/help.
