I've been trying to find out what is wrong with my PC, it started a few weeks ago, games I've been able to play suddenly have ceased to work, citing a failure in direct3D. After updating my video card drivers, rolling back my drivers to earlier settings and doing a complete system rollback (the rollbacks provided a brief fix, but that 's about it.) I'm about where I stared. I've posted the results from the dxdiag Direct3D tests below. Any help would be appreciated, and if you need me to clarify on anything, let me know.
