Google Chrome is the world's most popular browser, used by over 65% of internet users. When Chrome stops working — crashing, freezing, not loading pages, or using too much memory — it disrupts almost everything you do online. This guide covers every common Chrome problem with proven fixes.
Fix 1: Update Google Chrome
Many Chrome issues are fixed in newer versions. Update: click the three-dot menu (⋮) → Help → About Google Chrome. Chrome will automatically check for and install updates. Restart Chrome after updating. If Chrome won't open at all, uninstall it from Settings → Apps → Chrome → Uninstall, then download the latest version from google.com/chrome.
Fix 2: Clear Cache and Browsing Data
- Press Ctrl + Shift + Delete (or ⌘ + Shift + Delete on Mac)
- Set time range to "All time"
- Check: Cached images and files, Cookies and other site data
- Click Clear data
- Restart Chrome — this fixes most loading and performance issues
Fix 3: Disable Extensions
Extensions are the most common cause of Chrome crashes and slowness:
- Go to chrome://extensions
- Toggle ALL extensions off
- Restart Chrome and test — if the problem is gone, an extension caused it
- Re-enable extensions one at a time, testing after each, to find the culprit
- Remove the problematic extension permanently
Fix 4: Use Chrome Task Manager
Chrome has its own built-in Task Manager. Press Shift + Escinside Chrome to open it. This shows memory and CPU usage for each tab and extension. Sort by Memory to find the heaviest tabs — close the ones you don't need. If an extension is using excessive resources, disable or remove it.
Fix 5: Disable Hardware Acceleration
Hardware acceleration uses your GPU to render pages, but it can cause crashes with certain graphics drivers: Chrome Settings → System → turn off "Use hardware acceleration when available" → restart Chrome. This is especially helpful if Chrome crashes when watching videos or using graphics-heavy websites.
Fix 6: Reset Chrome to Default
This fixes persistent issues without losing bookmarks or passwords: Chrome Settings → Reset settings → "Restore settings to their original defaults" → Reset. This disables all extensions, resets your homepage, new tab page, search engine, and pinned tabs. It clears temporary data and content settings. Your bookmarks, history, and saved passwords are preserved.
Fix 7: Create a New Chrome Profile
A corrupted user profile causes persistent crashes. Click your profile icon (top-right) → Add → create a new profile. If Chrome works fine with the new profile, your old profile data is corrupted. You can import bookmarks from the old profile: chrome://bookmarks → three-dot menu → Import bookmarks.
Fix 8: Fix "Aw, Snap!" Errors
- "Aw, Snap!" — The page crashed. Reload. If persistent, clear cache and disable extensions.
- ERR_CONNECTION_REFUSED — The website's server rejected the connection. Try again later, or check if a VPN/firewall is blocking it.
- ERR_NAME_NOT_RESOLVED — DNS can't find the website. Check your internet connection and flush DNS:
ipconfig /flushdns - ERR_CONNECTION_TIMED_OUT — See our internet not working guide for network fixes.
Fix 9: Reinstall Chrome
As a last resort, completely uninstall and reinstall Chrome: Settings → Apps → Google Chrome → Uninstall. Check "Also delete your browsing data" for a clean start (back up bookmarks first). Download fresh from google.com/chrome and install.
Frequently Asked Questions
Why does Chrome keep crashing?
Chrome crashes are caused by: (1) Corrupted user profile data, (2) A faulty extension, (3) Too many tabs open consuming all available RAM, (4) Outdated Chrome version, (5) Corrupted cache files, (6) Incompatible software on your system. Try: update Chrome, disable all extensions and re-enable one by one, clear cache, or reset Chrome to default settings.
Why is Chrome so slow?
Chrome slows down due to: (1) Too many open tabs (each uses 100-500MB RAM), (2) Too many extensions, (3) Accumulated cache and browsing data, (4) Hardware acceleration conflicts, (5) Outdated Chrome version. Quick fixes: close unused tabs, disable unnecessary extensions, clear browsing data, and check chrome://flags for experimental features that should be reset.
Why does Chrome use so much memory?
Chrome runs each tab and extension as a separate process for stability and security. This uses more RAM but prevents one tab crash from killing the whole browser. To reduce memory: close unused tabs, use a tab suspender extension (like Auto Tab Discard), disable extensions you don't use, and check chrome://system for memory details.
How do I fix 'Your connection is not private' in Chrome?
This means the website's SSL certificate has an issue. Fixes: (1) Check your computer's date and time — wrong dates cause certificate errors, (2) Clear Chrome cache, (3) Disable antivirus HTTPS scanning temporarily, (4) Try Incognito mode, (5) If it's your own website, renew the SSL certificate. Don't bypass this warning for banking or email sites.
How do I reset Chrome to default settings?
Chrome Settings → Reset settings → 'Restore settings to their original defaults' → Reset. This disables all extensions, clears temporary data, resets homepage/search engine/tabs, and un-pins all tabs. It does NOT delete bookmarks, passwords, or browsing history. This is the best fix for persistent Chrome issues.
