I am looking for opinion on multimeter readings I am getting for power supply that may or may not be dead. System was found off and subsequently un-bootable after a power outage. Tower was plugged directly into the wall and not a surge protector.
20 pin connector wire readings while plugged into the board:
Purple = 4.96 V
Green = 4.04 V
Gray = 2.1 mV
The yellow wires to the P4 power connector, molex, and other power connectors are reading 1.2 mV each. From what I am reading here some of these are not normal readings, however I am new to using the multimeter so maybe a setting is wrong. It was set to detect DC on auto ranging? If more numbers are needed I can post them. Also makes no difference if the power switch is pushed, nothing changes on the readings. System is a Dell Dimension 9100 with 375 Watt Dell L375P power Supply.
