-- Information about the crash:
I am experiencing a common crash during regular use.
Both demanding use - Like gaming via Steam.
And also general use - Office applications, web browser, and code IDE.
The issue is common, happening about once per day.
The timing of the issue is common. Never when the machine is freshly restarted,
only after 2-4 hours of continuous use.
Often occurs when alt-tab is used to switch between a fullscreen window and a
windowed window.
It is more frequently repeatable when doing something GPU intensive like
Gaming.
It is more frequently repeatable in non-gaming the longer the user session has
been ongoing.
What happens:
using machine normally.
Often, a sound-blip will occurr, and input and screen content will appear to
hang.
(I.E. Video will stop playing on screen, game input will freeze, typing in
screen will not appear.)
During these events, it is possible to f-key into TTY 2,3,4 etc. so the machine
has not halted.
The screen will go black for 10-15 seconds.
It will usually come back in a new session. All applications closed.
Occasionally the session does not restart. After 30 seconds or so it is not
able to swap to TTY anymore. The machine appears fully hung.
However, it will still respond to network, like Pings. and SSH.
This indicates it is display-only that has ceased.
The crash can be reproduced sometimes.
