Can someone give me a guide on how to check my CPU voltage with a DMM? Thanks...

Hi, CPU Voltage is derived from the +12 volts. Without a schematic of the Mother Board or a good working knowledge of voltage regulator devices, I doubt that you will be able to find the test point. If a 3 pin reg is used, it will look like a power transistor, the test point will be pin three. Pin one will probably have the +12 on it. Careful, Jim
