Happened all of the 2 or 3 times that I played since I reinstalled everything today on my new SSD. I can play for over 1/2h, then I get a BSOD 124 with a bad sound loop, win7 does a memdump, and I have to restart
My OC is exactly the same as before when I could play for hours, I don't have trixx running, I have HWMonintor running but that never caused any troubles before.
I installed BF3 1st and whatever punkbuster it uses, then when I installed BC2 it installed/modified punkbuster, I know PB causes issues.
edit:I'm using norton antivirus that was on the CD with my MB, could that interfere?
