ok...so my girlfriend's computer, she has two. one is hers and the other is her moms. hers wouldnt turn on, turned out to be a bad psu. her mom's wont turn on, i think it may just be the power button. because it sticks, and just doesn't seem to work the way it should. but i asked if she ever spilled any liquids in there, and she said that her dog once pee'd on it...so yea, after washing my hands, i figured that would be the problem, but just in case, do you think any other thing would contribute to the power not working? everything is hooked up to the motherboard correctly, and the psu i believe is working normal. either way, i replaced the psu with the one from my computer, that i know works, and it still didn't work.
