Ok, I bought a Multimeter from RadioShack so I could see if the sensor on my mobo was bad. My mobo reads my 12v rail as outputting only 10v's. There are a bunch of selections on the multimeter to set it to when testing but I'm not sure which one to have it set on. I'll attach a picture so you can see all of the options to select from. I just need to know which one to put it on to test my 12v rail voltages.
