Random crashes mid game

[Fhokuz]

I have been playing the game for a day now, but since the first games i've been getting random crashes mid game. The only solution i have its to use the ctrl+alt+supr combination to close it.
I've checked the crash dump in the appdata folder and i get the next codes:

Exception Code: 0xC0000005
Exception Address: 0x004A5942

Would love to get a solution for this problem, i'm loving the experience of playing MW3 after all this years.
