I just got a multimeeter to test the 5v line from my power supply. My computer is acting like there is no CPU and I am trying to determin if the PSU is way outa wack, CPU dead, or mobo DOA.

So how do I use this thing? never used one before. And what various things should I test?

I just need some general info. Like what I should be setting the multimeter to, The PSU says 100-120Vac/200-240Vac so should the multimeter be set to 250V?.

And I don't really know how to read the scale:

V-mA 0 50 100 150 200 250
0 10 20 30 40 50
AC-10V 0 2 4 6 8 10


When I test the molex connecters with the multimeter set to 250 on the DC side I get a reading of 50 from the yellow wire, and between 0 and 50 on the red wire.

Is there some way to test the motherboard to see if the CPU is getting power?

TIA
