Can't post this in the other GTAV thread as it would just get swallowed up.
Played this last night for 3 hours and it was perfect.
Came on today around lunch time and now it crashes every time within seconds of starting the game. Game loads, I start play, game freezes. When I Ctrl-Alt-Delete, all I get is this:

I have the latest drivers, which were installed last night before I played, so I'm sure it's not that. The only change has been a small Steam update today.
Checked Rockstar Support, nothing.
Any ideas ?
