Minh's Struggle with Browser Sluggishness

Minh, a 28-year-old marketing specialist in Ho Chi Minh City, noticed his browser freezing constantly during heavy multi-tab research sessions. Frustrated by the lag, he assumed his PC needed a total hardware upgrade.

First attempt: He blindly cleared all browser history, saved passwords, and cookies. Result: He got locked out of half his work accounts and spent the next hour resetting passwords in a panic.

After calming down, he realized he only needed to wipe corrupted cache files rather than wiping his entire profile. He cleared just the cached images and files.

Result: Pages loaded smoothly again without losing login sessions, proving that targeted cache management beats aggressive full-data wipes.
