Graphical Glitch - ATI 4870 HD

[redfirebird87]

Hey all, was wondering if anyone has any input on graphical glitch I'm having shown below. I think it's only when there's shadows being rendered from fire / explosions.. any other time the rendering is fine. I have it in Skyrim and Eve Online. I've looked around here and on the web but can't find anything similar. I've tried messing with the settings in CCC but it seems to have no effect on this. Any info is appreciated.

I found another example of the problem that I wanted to add. The halo's around nirn root locations have the same kind of lines. Could this be DVI corruption, or does that effect the entire image? I've tried cleaning drivers and doing a fresh install tonight, but still no fix. Other than these little annoyances everything seems fine..

Any insight would be greatly appreciated.
