ATI Display driver errors.

I'm not exactly sure what these mean, but I have a bunch of these in the ACEEventLog under Event Viewer. These usually come up at random times, but it also happens when i get a black screen upon resuming from hibernate or sleep.

Any ideas on this?

I also keep getting this error whenever my Laptop restarts starts.

I have an ASUS G73J with a 5800 RAdeon.
