what you need to do is ground out you tester (black probe)

now using the red probe test the voltages
red wire = 5volt
yellow wire = 12volts
if you get those results move to the ATX connector
again ground out you black probe to a black wire
and test your wire for the voltage
orange should be around +3.3 V
red should b e around +5.0 V
yellow should be around +12.0 V
White should be around -12.0 V
those are the only one i remember
but you need to complete your circuit with a + (to the red probe) and - (to the black probe) wire the only time i know of this not appling is with the white wire and one of the yellow wires which gives you +24 voltor the red +5V with the Yellow +12V which gives you +7V
let us know what you find

I did what you said. I put the black probe on the black (ground) wire and the red probe on the others. I got different results (probably worse) than the first time.
Here they are:
WIRE Volts
Brown = 1.3
Brown = 1.3
Brown = 1.3
Blue = 0.0
Black = 0.0
Black = 0.0
White = 0.2
Red = 0.2
Black = 0.0
Black = 0.0
Black = 0.0
Black = 0.0
Red = 0.1
Gray = -16.8
Brown = 1.3
Green = 5.06
Red = 0.1
Red = 0.1
Orange = -2.7
Pink = 3.323
White/Bluestripe = -15.5
White/Redstripe = -14.5
Brown = -0.6
*Note the striped wires from the first results*

I'm stuck and I want to use my computer again. I don't know if this is enough info for any one to give a hint on what's wrong with my computer. Any help will be greatly appreciated. Thx in advanced.
A black monitor on boot could be an unsupported framebuffer mode. Usually the way to test this is to boot up the computer and leave it running and try login in blind to see if X will start.

I tried doing that a while back before I started this thread. I never got the X to start. :/

Since I'm getting different results I'm starting to think I should get a new power supply. I don't know maybe I'm doing it all wrong. OH GOD! I'm getting depressed.
Now, a thing you guys should know is that I live in the country side up in the mountains. Everytime there is a tropical storm there are frequent lightning strikes around and on the house where I live. Also there are frequent power outs. Sounds scary but thanks to God no one gets hurt in those storms, well, at least for the fifteen years I have been living there. Well, enough of me.
If it is the power supply that is messing up, can it also be the voltage regulator that is not giveing the right voltage to the PC? If it is, where can I get one? Or do I have to buy the whole power supply?
*Which is probably better for me to get the power supply.*
