Yes, the video card is doing crunching but the work unit was at 99% and stayed there for about 30 minutes. And then dropped down to 88%. I am confused, hehe.
Bruuce, I'd take a look at the Logs. You should be able to suss out some unexpected error that caused your GPU to "fail". If nothing too obvious jumps out, head over to the Folding Forum and check to see if you have an issue someone else might have encountered.
