Switch your digital multimeter to continuity mode (diode/beep setting). Connect the black probe to a known chassis ground layer. Use the red probe to test both sides of the surface-mount capacitors surrounding the CPU, GPU, and Chipset. If both sides of a capacitor beep continuously to ground, you have identified a shorted power rail or a failed decoupling capacitor. Resources for Finding the Files
