To check any component's voltage on computer motherboard using digital multimeter, first you need to know some informations about how to use a multimeter. We are talking about computers so I'll guide you about that because with a multimeter you can check many other devices aswell.
Warning : If any kid reading this, please don't try this at home.
Connect the black wire of the multimeter in the port marked as com on the multimeter and insert the other red wire just above the Com port. Multimeter has a digital screen and a regulator. Around the regulator there are few sections, each for measuring different things like AC current, DC current, resistance etc., because we are talking about computers here, we'll focus on DC current section.
DC current section marked as 200m, 2000m, 20, 200, 1000 volt. Computer only takes -12 to + 12 volt so we'll set the regulator pointer on 20 to measure exact voltage.
Warning : Don't set the regulator below 20, it can damage the motherboard or the multimeter.
Note : To chech RAM slot we need to know some informations about SMPS
Tip : Cut the power off from the computer
SMPS have a 24 pin ATX power connector and other connectors to power other peripherals like hard disk and CD/DVD Rom. Remove the connecters from the CD/DVD rom and also from hard disk, but don't remove the 24 pin ATX connector from the motherboard, because we need to give power in motherboard.
Tip : Don't have to take the SMPS out from the cabinet, just remove those connectors.
Smps carry -12 to +12 volt, each colour of wire carry a volt within that, and the black wire carries 0 volt (ground)
Now insert the black lead of your multimeter in the pata (IDE) power connector port which is connected to a black wire. Now power onn the Smps and use the red lead of your multimeter to check the ram slot. (locate the pins of ram slot on the back side of the motherboard. Usually you will get voltage around 3.5v / 5v and from some pins 0 volt).
Warning : Don't try to measure any other component with this setup
