My computer has been running fine for as long as I can recall. I haven't attempted to install any new hardware; the only thing that has caused me any concern is the fact that my ethernet port on my mobo got blown in one way or another (not sure if it was lightning or a router going bad). Suddenly, today, I come home, hit the power switch only to find that the computer doesn't attempt to boot, no fans, nothing. There are lights on my mobo that are functioning, but I've read on these forums that mobo lights functioning doesn't equate to a power supply being good. Is there any way to tell which component of my computer is bad without swapping out power supplies?
