AFter I moved my computer (house to house), it "won't turn on." By this, I mean, pushing the power button does absolutely nothing (no fans, so faint beeping, no anything). The first time it happened, I thought maybe the power switch was busted, so I switched the Reset and Power connectors from the case to the mobo, but that did nothing. After maybe 10 minutes of randomly pushing things, eventually the computer magically started up. After it was up I tested it by shutting it down and then pressing the power button, and it turned on just fine. (i.e. once it was up I could turn it on and off again without any problems) However, since then, every time my power goes out or I turn the machine off for some reason (vacation, etc.) and I have to restart the machine, it never turns on for the first 10-15 minutes, but eventually magically decides to turn on. This last time, though, I seem to be unable to get it restarted at all, so my machine is completely dead. So the quick question (with the long description ) is: which piece of my machine is likely busted and in need of replacement? The power supply or the mobo? Or something else? I have ruled out the power switches, as swapping it with the reset button does nothing, and the outlet is working, as I have a second machine plugged in which works fine. Also, once the machine is up and running, it runs perfectly fine for days, weeks, months at a time. Thanks!
