What kind of message do you get? Nothing?
Or it's another: The AMD display driver crashed and has recovered?
Try this: 1. Open CCC
2. Unlock and Enable Overdrive if they aren’t already.
3. Go to Options/Profiles/Profiles Manager. Create a new profile. Under composition make sure “ATI Overdrive” is checked. Save and Close, DO NOT ACTIVATE.
4. In windows go to: C:\Users\{yourusername}\AppData\Local\ATI\ACE\Profiles (you will need to have “show hidden files” turned on for this)
5. Open the xml document with the name of the profile you just created (notepad is fine)
6. Change the values of the Clock and Memory speeds to look like this (these specific values are what worked for me and my card, use judgment) EDIT ONLY THE BOLD VALUES.
