I had the same problem for over 1 month with my gtx260.
Tested new drv and tdr fix all that you can do.
The card was tested at dealer and no problem. Replaced mobo, bought new memory new hdd .. still same problem. Bought e new nexus 600w powersupply.
Nothing did help.
This was the solution.
I downloaded nvflash. Made a bootable usb stick. Made a copy of my gtx260 bios with nvflash.
Modified the bios using NiBitor. Changed the value voltage (extra) from 1.12v to 1.06v
After that working fine.. Get the same points in 3dmark 06 and vantage. But my system is stable.. And i never get nvlddmkm bsod anymore
Here is a page that can help u flashing bios.
