It was running flawlessly after I reinstalled because it kept crashing on loading screen after difficulty choosing. But now it works for a good 5-10 minutes, than completely crashes on me. No warning on crash, just freezes for a few seconds, and find myself at my desktop. I have an HP Pavilion DV7, 2.2Ghz (Turbo to 3.1) Intel Core i7-2670, AMD Radeon HD 6770M graphics card, 8Gb DDR3 ram, Windows 7 Home Premium (64-bit) and I'm running it on medium settings. I also tried low to see if it will continue, and it does. It never did this, after I reinstalled it was working flawelessly. If I were to guess, this all started as I was entering a cutscene (not saying which for spoilers sake) that's when the crashing started. Any ideas? Thanks.
