Hi, I'm new to these forums and you all seem like a bunch of good guys, so I decided to try here for help. So heres my problem. I have a Dell Dimension 9100 that I bought back in '05. I'm pretty sure my warranty is up but the thing won't turn on. I thought maybe it was the power supply so I went and grabbed a new one and threw it in but the only difference was that the fans would periodically spin. Heres a little more information about the problem. The green LED indicator on the motherboards turned on no matter which power supply is plugged in. Could it be the motherboard is shot? The processor? I don't have too much experience fixing these things and any help would be appreciated. If you need any more information that you think I left out just ask.
