Thanks everyone for your input. The other pc I have is much older and sadly its not the same type of battery that this desktop takes so I wont be able to test that. I also tried to run it with just the motherboard and nothing happened. So I assume that is the problem, but I'm still quite unsure. Ive tried everything that I can think of at this point so I'm just gonna take it to a computer repair guy tomorrow... (and they will probably gouge me with a crazy price) but its important that i get this fixed and w/e it is that is wrong with it I clearly cannot fix, or dont know how.

But thanks again everyone for your input.
