However, it's entirely normal for the framerate to drop when explosions occur on the screen... with any game really. This is because there a lot of calculations for your graphics card involved when an explosion occurs and your graphics card can only do so much operations in an arbitrary time period. When the explosion is over, the framerate will go back up again. (For the dense people around here: yes, that is also the case with consoles.)
So if you're wandering around and nothing's happening until some big ass military plane comes falling outta the sky, crashes right next to you, over nine thousand enemies start crawling out, start shooting and throwing stuff at you inducing quite a lot more explosions, trees start to fall over because of the bullet rain which in turn cause a lot of earthquakes... then yeah, your computer will be quite a bit busier than when you were happily walking the dog.
I know your CPU is a Core i7 920, which has no problems at all keeping up with BFBC2. I don't know what kind of graphics card you have, but chances are that it's not enough for BFBC2. So you want to either try upgrading that, overclocking a bit or lowering the graphical details in BFBC2 itself. Or just accept that you're going to lag a bit in explosions.
