Yesterday, as I was working on my computer, it died. Just as though someone had unplugged it. I knew I had a short, so I tried a new power supply cable. When I got the new one in, I hit the power button and the power supply unit popped and started smoking. I now know the short was in the unit itself. So I picked up a new power supply unit and installed it. The problem now is that I have power to my computer, but nothing works. For example. The power supply unit fan runs and the processor fan runs. The light for the CD Drives comes on for a quick flash then goes off. The green light that usually indicated the computer is on flashes on and off once. But I cannot get my CD drives to open and I cannot get a display on my monitor. What are the chances that when the power supply blew, it took my motherboard (or at least parts of my motherboard) with it, and how can I tell before I buy a knew motherboard?
