SOLVED BSODs during games blamed by ntoskrnl.exe

[El Diablo]

Both times I was trying to play New Vegas when I got those blue screens.

I wasn't aware I was using gigabyte utilities but I'll disable them too.

Alright I had the chance to try a different GPU, which also happened to be a 560Ti factory overclocked to 900Mhz. Slightly different configuration with 2 fans and a bigger heat sink though.
Unfortunately this didn't make a difference as I tried to play New Vegas before and after and both times I recieved blue screens, dump files attached.

I don't know if it is just the game or something completely different, but it seems apparent that my graphics card is ok.
