CO2 exists as a discrete single molecule as O=C=O. and due to only van der waal's interactions the intermolecular forces are not strong enough, allowing the molecules move about freely, hence it exists as a gas.

Due to this the intermolecular forces are tremendously high and molecules cannot move about freely, Hence SiO2 is a solid.
