Put both CPU core into the task haven't got any problems. but when CUDA task is running, system crashes with BSoD within few minutes.
in the past version of OS(Vista) worked very fine and nicely.
What is wrong with this computer?
I've installed Lunatics optimize before I get the first normal tasks. Should I take this off and get some normal task?

I've been though this problem before. at that time, I solved by installing CUDA developer driver.
This time doesn't work at all.

After issues about workunit shortage, I haven't reported a single CUDA task. I'm in need of someone's help.

//following sentences are my system info

OS: MS win7 ultimate 64bit

What does the BSOD say?
Check in Event Viewer (Control Panel->System and Security->Administrative Tools->Event Viewer->Windows logs->either Application or System logs) for more information to give.

Did you upgrade from Vista to 7, or did you clean install Windows 7?
Did you fully update Windows 7 (Control Panel->System and Security->Windows Update->Check for updates)?
