I have an issue with my GPU folding client : sometimes when the WU is almost finished, it will stay at 99.99% completed, there are 4 seconds left, but the WU is not sent. Card is a Radeon HD 7850. Stopping the folding and restarting the PC does not solve the issue. Any ideas? So far the only way to make it work is to remove the gpu slot and re-add it again, but in this way I loose my processed WU.
