I'm playing a mage character on a new computer, only to find that fire spells and Unrelenting Force have a thin ring of black pixels around them, and fire from dragons also has black pixels around parts of the stream. I don't know if any other spells or Shouts do this, but it for certain does NOT happen with ice spells, lightning spells, frenzy spells, or calm spells.

Any ideas?

Try using FXAA instead of Antialiasing.

The NVIDIA Control Panel says FXAA is not supported for Skyrim.

Hello, anyone who has an Nvidia card will get the black lines/pixals around fire and healing spells, you will also get a few black lines around burned down houses and sometimes dragons. It is an anti-aliasing problem caused by having 8xAA on, putting the game to 4xAA fixes this. I think 1.6 caused this problem. regardless of what nvidia drivers you use you will have this problem. so until nvidia or bethesda fix it just play using 4xaa.

EDIT: Skyrim does support FXAA in the launcher options not through the Nvidia control panel, but i advise using 4xaa in game and using 2x supersample transparency from the nvidia control panel. If you use multisample transparency alot of NPC's are see through, this is an engine bug and cannot be fixed. Also FXAA blurs everything too much.

Cool beans. Thanks DarkNye87, that totally fixed it.
