It seems like I only complain on the programs you use, Teac, but have you run Lavasoft
Ad-Aware after installing those dancers? A little bird whispered in my ear that those were full of spyware and other junk. Might want to check it out. I don't think it's got anything to do with the sound-card (Could be wrong of course). If you choose a different screen-saver than the Aquarium, does PC Health kick back into action? If you remove the Aquarium completely? (Including using the
registry cleaner (right-click and choose save)) Keep at it and we'll crack this one...
