Seg Fault

Hey,

There is this weird problem happening. All of my CUDA programs are giving a seg fault even the SDK examples.
They were working pretty good till before but I dont know what has happened that everything is giving a seg fault.

Please help me as to where should I look about.

The problem that I found was that none of the devices support CUDA. I got to know this by running devicequery.

But howcome this happened suddenly and what should I do now?

Try to update the cudadriver.
