firstly can you write down the error code from the blue screen? (If it flashes too fast and you cannot get it, download bluescreenview program and use that to look up the crash dump)
Blue screens typically point to driver or hardware problems...
So, lets start with
- have you updated all your drivers, especially GPU to latest?
- have you ran memtest on your RAM?
- what PSU do you have? (make and model, with link if possible)
- Do other games run ok?
