Runtime failure for simpleGL and simpleD3d

Getting errors on just two of the sample programs, help appreciated. simpleGL writes:

Cuda error in file ‘simpleGL.cu’ in line 326 : unspecified driver error.

simpleD3D writes:

Test FAILED

All other cuda samples pass fine in debug and release. All samples including gl and d3d run fine in emdebug/release.

Running cuda .8 beta under windows xp pro on new dell xps 710 h2c (intel quad 6700 and dual gtx, single monitor, sli turned off, forceware 97.73). Would suspect glut but then dx fails as well, dx Feb 07 sdk installed and those samples run fine.

Help appreciated am hoping to start working with a clean slate.

Thanks
