Hello to both raison & scotty813!: did you both update the CCC software & drivers periodically to get the best possible performance or new features from the video card?
if you did then look for an updated driver for both of your PC's
after this download go back to AMD & download the latest driver
that happened to me with my Pavilion 410y until November 2012
I ended up with a Blue Screen then the screen went from 1280 x1024 to 640 x480
& it said that the driver failed
I think that the original driver was buggy
but ever since I did that 2 step procedure I've had nary a problem
good luck
hope this enlightens & helps
