I've recently bought a new desktop C2D system with an ASUS ATI HD4870 512MB graphics card.

Every time I try to play Trials 2 (I've got the Steam version), something will crash.

Either the ATI driver alone, or the ATI driver along with the game itself.

The core temperature didn't exceed 60 degrees C, and I haven't noticed this crash in any other game that I've tried.

The ATI driver recover program says that the video card stopped responding to driver instructions, and the Trials 2 error says "Unfortunately your graphics adapter doesn't have enough video memory to run this game. This game needs at least 64 megabytes of dedicated graphics memory to run.

m_dxTex is null"

Disabling the driver recover program just causes the system to completely crash.
