Was in the middle of playing and my computer just shut off. Never done that before.
Attempt to turn it back on and it tries for a few seconds, then “restarts”, tried again 2 or 3 more short times and shuts off.
Waited a couple moments tried again and it tried to boot up a bit longer (believe I should have seen something on my monitor but nothing) then shut down and tried again for a couple of short seconds then stopped. Keeps doing that now.

Graphics card? Has my GTX 970 packed it in after 3 years?
