BSOD playing Battlefield 3

[pressurepoint]

Hey all,

So I've been getting intermittent BSODs while playing Battlefield 3. I say intermittent because there are times when I'm not playing (e.g. browsing) and I get a BSOD.

I've been doing a bit of research, and according to BlueScreenView ntoskrnl.exe is the driver at fault. I'd like to attach the .dmp file but I'm getting an error regarding permission even though this is my PC...

There's a lock symbol on the Minidump folder and I don't see any properties that allow me to modify this.
