    Desktop CPU - Power problems

    Came back into my office to find the Power LED on my desktop flashing on & off about once a second. CPU would only respond to holding down power soft-switch. Once got PC off, waiting 60 seconds, then tried to power-on. When this wouldn't work tried combinations of unplugging & waiting and turning off power toggle on power supply...then turning back on. When CPU recieves power from wall plug - or when hold down power soft-switch for 5+ sec & let up - speakers pop & power LED flashed _briefly_, then nothing. Tried removing CMOS battery from Mobo & taking CPU completely off power for 30+ minutes; no effect. No BIOS beeps, no fans - case or power supply - turning, no nothing: it doesn't even _get_ to POST.

    Am running an ASUS A7V266-C with 512MB Memory which - until about three hours ago - was solid as a rock.

    Anybody seen this before?

    Yep, sounds like a dead Power Supply to me. If you haven't knocked the case over or anything, there is no reason your power supply connections should be loose or your power switch connections either, but you never know. My bet is the Power Supply itself is gone. Have seen it happen more then once. Especially since your Power Supply fan isn't working.

    You may also want to examine the capacitors on the motherboard. They are the items that look like small soda cans. The tops frequently have hash marks with three prongs or an "X" shape. They should not be bulging and should not have any sandy colored or black goo on them. If they do, your power supply has allowed more voltage than your motherboard can handle and your capacitors have turned that extra voltage into heat and blown. The good news is that your CPU and memory is most likely okay. The job of the capacitors is to protect these.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!
