Hello all,
I have an AMD HD 7970 overclocked to 1200/1525MHz running CGMiner on Windows 8. Since I received my new 7970, I have been mining happily for about a day without problems. Then, mid-day today, I got errors from CGMiner and it had stopped mining. Upon further investigation, after this happened a few more times, I saw that windows event viewer said that around the times this error occurred, my display driver had stopped working, but recovered giving me the error;
"Display driver amdkmdapp stopped responding and has successfully recovered."
This is happening more and more frequently while mining and every time it does I get the CGMiner error;
[2013-03-24 11:43:31] Error -6: Creating Command Queue. (clCreateCommandQueue)
[2013-03-24 11:43:31] Failed to reinit GPU thread 0
[2013-03-24 11:43:31] Thread 0 no longer exists
Every time I could close CGMiner and then open it back up and it would work fine, but now when I put in my pool info, it crashes immediately and gives me the windows event viewer error;
Faulting application name: cgminer.exe, version: 0.0.0.0, time stamp: 0x514557a8

Finally, as this is happening, I have noticed that Afterburner says that my GPU is constantly spiking up to 40% usage, then back down to 0%.
Please help
