BSOD only when playing Battlefield Bad Company 2

Hi,

I've upgraded my pc with

I5 2500K
Gigabyte P67X-UD3-B3
Corsair Vengeance 2 x 4 gig DDR 3 1600 mhz
Corsair TX 750 watt V2
Asus 560 gtx ti

My os is W7 ultimate x64

Now when I play Battlefield my system crashes to blue screen, I've got no idea why. And a another problem I have is when I'm surfing on the web, my screen goes black and I get a notification that my driver did go bad and has been fixed.

I'm thinking there's something wrong with the videocard or motherboard. Do I need to flash my motherboard?

Thx for the quick reply, gonna update them and report back.

Thx again :)

So I uninstalled EasyTune, and installed the Razer Lycosa driver, as I didnt install a driver for my keyboard yet. Then uninstalled punkbuster, rebooted and installed new punkbuster manually.

Fingers crossed

Now gonna play battlefield a bit

No blue screen so far, gonna play some more tonight and report back.

Just had a crash of the graphic driver, the computer didnt go to blue screen but, the screen went black and then notification with: graphic driver didnt respond and has been repaired.

Forgive me for my bad english as it is not my native language.
