Crysis is locking up

I highly doubt it has anything to do with a virus. I recently beat this game and the tanker was the only part that really, hmm, effected(?) the performance of my computer. It stuttered a bit, but not below 20fps, which is not bad at all to me. So stuttering was not a problem for me, on that level what my problem was was that it kept crashing. Nowhere else in the game did it crash. I have my settings all on very high (except for objects on high) 1440x900 with 2xAA. I solved the crashing by playing the boss segment in DX9, because this is really the only place on the level where it crashed.

In DX9 it did not crash for me once, so try that out just for that segment if you have to.

Also I noticed that the fire on the deck only appears*(blips in basically) when the second boss appears...anyone know a fix for that?
