I have been having problems with TDR lately. But it only happens in certain situations.
If I am rendering something in Sony Vegas 11, and I go fullscreen on some things, I get the BSOD. It almost always happens in Minecraft.
I have tried both ATI's Drivers
and the ones provided through Windows Update.
