Where to find Google Chrome logs
First, you must enable crash logging in advanced settings by ticking "Automatically send usage statistics and crash reports to Google".
Crash logs can then be found in chrome://crashes.
Note that by enabling this, your crash reports and stats will be sent to Google servers...
Dump files are stored under %HOMEPATH%\AppData\Local\Google\Chrome\User Data\Crashpad\reports
