lol well i went out and got another PS to see if the other 2 were duds (my dad has about 50 old comps... i didnt pay for any) and i figured out the problem!! WAHOOO!!!
when you connect the green wire to black i thought that the green wire you were supposed to use was the one that connected the metal part of the PS... i saw another random green wire coming up from the board and disconnected it and connected it to the black and WALAA!!
now i have 2 more that will work very easily!! anyone interested in buying a power supply? lol
