Lately I have been trying to reduce power consumption on my desktop build stated in my sig. To cut to the chase I want to know if there is any way to disable one of my pci-e slots in the bios. Namely my pci-e slot holding my hd4850. I have onboard graphics aswell and many times there is no need for the 4850. Don't get me wrong I use the 4850 to its fullest on a weekly basis but not all the time. I want to disable my 4850 in order to switch to onboard graphics without physically removing th ehd4850, possible?
