Hey, well I just built my computer and well it won't even start. I bought all the stuff and I'm pretty sure i put everything in place. I plugged it in and nothing moves, no sound no nothing. Once the light turned on for a bit but the fans weren't moving or anything. Why does this happen? Does this affect everything else? Is my mobo,cpu etc fried? I have a usb plug which I didn't plug in, can this be the reason? Or is there a way to activate the mobo before I plug in the power?
