This happens every so often with this new card I put in my computer. Let me detail what I've done and what I have going on:

Using cgminer 2.11.3 on Windows 8. Have tried both this version of Catalyst and the 13.3 beta. Every now and again, I get a message that my display driver has crashed and restarted, but I am unable to get any sort of work out of cgminer until I restart my computer.

If I restart cgminer before I restart the computer I get this:

Display driver amdkmdap stopped responding and has successfully recovered. [Event 4101, happens three times]

I was not having this problem when I had two 7950's installed in my computer. I removed them and installed one 7970, and I've been having these problems. I can't run cgminer for more than a few hours before it stops. I had tried so many different things with different drivers and different sweepers that I formatted my hard drive and reinstalled my OS with 13.1. Before I start messing with the drivers again, I'd like to see if anyone has any advice as to what I can do to fix this problem. The 7970 is at 1125/1575 on stock voltage (1.175 I believe)- I have the same issues when I run it stock.

Thanks in advance! If there is any other information I can provide, please let me know.

Try an earlier driver and back your Memory clocks off, way off.
