Well, I install the game, min requirements check out and then I play the game. I reach the crash site, continued till it was night and I had to find my personal belongings. Then, the game starts lagging, sometimes it just freezes for a minute and then BSOD....

And it's cos of ati3duag.dll... now I don't know what to do, I tried replacing the file with a downloaded one in safe mode but my PC became worst. So I just restored the original. So now I need help!

My PC is:
Intel(R) Pentium(R) D CPU 3.00GHz
1GB of RAM
Ati Radeon X1300 series
