That's the ATA Ribbon cable that's going to your hard drive. It should be replaced. There are service manuals that explain how to replace it.

If you're not comfortable removing the logic board, you might want to have a service provider do it. Laurie -- AOL IM/iChat: cubeownernyc http://www.cubeowner.com Home of The Mac Cube FAQ!
