Answers :

1/10th a volt? Nope.

Bypass the Power On switch. See if you have a bad switch first.

Then test the power supply. If the power supply comes on by bypassing the Power On switch, I'll bet you have a weak 12 volt voltage power rail.

1) Yellow wires are 12 Volts
2) Red wires are 5 Volts
3) Orange wires are 3.3 Volts
4) ANY Black wire is a Ground wire

They do sell power supply voltage testers, should you not wish to use a multimeter set at DC volts.
(0 - 50 Volt scale)

I prefer a multimeter.

A) ALL the light use less than 1 Watt
B) EACH fan uses 2 to 3 Watts

C) A typical Processor uses 55 to 125 WATTS.

You have to turn the power supply on, by jumping the Soft Power On wire to any ground wire.

This is also the way to bypass the Power On switch, to see if the switch is bad.

Do you wish to proceed?
Check the power supply wether it supplies all the needs of the mother board, then remove the cmos bat and ram for 10 minuter then try starting ur comp, gud luck.
