I thought I needed a new psu. I replaced it. All it does is run but know video signal. I tried different video card. Still the same. Whenever I plug the 4 pin power adapter it won't start at all. It may just start the fans for a second. But when I disconnect, it just runs. I did try a different processor, same results. I did find out the hdd was bad, but it still should boot to bios? Don't understand why it won't power up when I plug the 4 pin adapter in. Maybe I have 2 bad processors. Tried different memory too. thanks cfuller77
