Step-by-Step Fix

Open Chrome Task Manager – Press Shift + Esc (Windows) or go to Menu > More Tools > Task Manager. Identify tabs/extensions using high memory and end them.

Enable Memory Saver – In Settings > Performance, turn on 'Memory Saver' to free up RAM from inactive tabs.
Clear Cache and Cookies – Go to Settings > Privacy and security > Clear browsing data. Select 'Cached images and files' and 'Cookies', then clear.
Update Chrome – Ensure you are on the latest version via Menu > Help > About Google Chrome.

Alternative Fixes
