HELP: ocean effects display problems(screenshot)

http://forums.avsim.net/user_files/146602.jpgThe ocean just turns into a textureless/artifact-like area whenever gauges are visible in any aircraft's 2D panel. The ocean looks fine for the first few seconds, but then it turns to the mess in my screenshot. It doesn't happen in any VC. I have a Radeon 9800 (a little old...i know) but this hasn't happened to me before, it has only happened with the recent Catalyst driver versions. The most recent changes i've made to my system is the transfer of files from my old ATA133 to a SATA HD(also making the SATA drive the booting drive) and the installation of new Catalyst drivers. I've noticed that some files from the transfer became somewhat corrupted. could that be the cause? thanks
