Ok I didn't get a red screen, but Fallout 3 did freeze / lockup. Had to shut down the computer.
Now that PC is very stable, not overclocked and I've played BF4 and other games many many times.
I'd like to try another game and see if the same thing happens. For some reason I don't have Grid, could have sworn I bought it on Steam...
Might try Crysis in DX9 mode.
EDIT: Game works fine so far. I will do the same as with Fallout 3, just let it sit this afternoon and check in the evening. Graphics are superb, even in DX9. I'm getting around 70-120 fps depending on what you look at.
But being a DX10 game really a faster card than a GTX660 would make sense. Can't wait for Nvidia to release the next cards after the die shrink. The performance jump should be HUGE.
Also I checked the Fallout 3 page and it states:
Notice: Fallout 3 is not optimized for Windows 7
Try this workaround:

I haven't tested it yet though. But will if Crysis still runs in the evening. I don't see why not, haven't had issues playing older DX9 games in the past.
