Random crashes

[Schwarzie]

Greetings.

I already send a message to official Turbine Support, but maybe someone here has the same problem and can help me.

Since last weeks patch i have random crashes. It is irrelevant if im in a group, if im in a dungeon or at the market. These crashes simply occur after i was some time in game. in 75% i get a freeze ingame and if i tab back to desktop theres a message window telling me that DDO stopped working properly. In 25% i get a bluescreen and have to reboot my comp.
