[SOLVED] Windows 7 64 bit crashes constantly with games - APPCRASH - Fault Module Name: d3d9.dll

Greetings,

I had Vista 64 and now upgraded to Windows 7 64bit.  80% of my games crash on load.

As other I have googled the shiznit out of this, it seems most people crash some time into a game, I crash without the thing loading at all.

My setup.

Surprisingly Crysis works, Company of heroes also.
