Quick background: work laptop, nothing fancy, used daily for our company intranet. Since this week I get the Aw, Snap page within a minute of loading it.

Aw, Snap!
Something went wrong while displaying this webpage.
Error code: Out of Memory
The little line at the bottom reads RESULT_CODE_HUNG. I tried incognito and it lasted a bit longer but still crashed eventually. I really dont want to reinstall Windows over a browser tab. Is there a proper way to find out what is actually killing it?
