Agreed with EpaX's solution for your chat buttons.

As for the vents and the flash nades, I agree with Carmaste. Check out your video card.

If your old computer still works, I would suggest using it, but I'm guessing it's not, since you bought a new one in the first place.

If you're having these problems with the fire nades and the gas vents, the gas grenade and the flash grenade might have this problem. Maybe the smoke too, as well as the gas in CF and BL.
