I am running Windows 8 Pro 64-bit with an XFX AMD Radeon HD 6870 video card. My version of the Catalyst driver is 2013.0328.2218.38225, which I believe is the latest-greatest-up-to-datest one. All Windows updates have been applied. Every so often - once a day or more - I'll get a popup telling me that the Catalyst driver has stopped working. That's it. No more information is given and there is no impact on system performance that I can detect. After a few seconds the popup will go away and everything continues as though nothing had happened. Any ideas what might be causing the driver to stop working? Any known fix, patch, etc.? Thanks.
