I tried the new gpu miner in the OP.

Ran fine for about 3 hours then I had the lock up again . I am puzzled at what is causing this.

I have no issues at all running my Nvidia cards but can't get the AMD to stay up and running.

Using Windows 7 64bit driver 13.12. I thought maybe driver issue but someone else posted same issue using driver 14.7 on Windows 7, though not sure if they are on 32 or 64 bit.
