My computer won't turn on. I went to Radioshack and bought a few switches so I could turn my fans on and off. But I first thought that I should organize the power cables so that the fans are all getting their power from one main cable. So I unhook the power cables from everything except the motherboard. Then I hook them backup up in the way I thought would be the neatest. I hook up the side fan and I also hook up 2 of the rear fans. So my hard drives, cd rom drives, floppy drive, and 3 fans all have power cables going to them. So reconnect the power in the back and turn the PSU on and press the on button. Nothing happens. I try it a few more times and nothing happens. So I take of the front panel to make sure that the on button is still connected and it is. Nothing seems to be wrong. But something obviously is since my computer won't turn on. It was working fine before I disconnected everything. HELP!! What should I do??
