i was taking out the floppy drive from my pc and now it wont turn on. i took the drive out fine. no probs. i took one cable out. no probs. hte other cable was going from the motherboard to... nothing. so i removed it and now my pc wont turn on. i put it back but still nothing. the psu powers up and the dvd readers flash but the cpu fan dosnt power up. ive tried replacing the floppy, swaping wires, everything. it wont power on. any ideas?
