the reason it keeps finding it is because you removed it from DM. When removing it from DM and a reboot it will be found all over again. The only way to make it not do this is by going into the properties and choosing disable in DM... however, I wouldn't suggest that. Sounds to me like you need to install your chipset drivers for the MBD.
If you argue with an idiot he will drag you down to his level and beat you with experience.
