Hello. I was doing a fresh install of Vista on a new machine. Everything went great until I went to Windows Update to grab the "Optional Updates." I don't recall which exact ones I selected, but it was most of what was available save the language packs. Everything downloaded find, and the system rebooted as normal, and then the power died.

I switched the machine back on, it started to boot, and then died again before POST. NO beep codes, just fans start, 3-5 seconds or run time, then *poof* power off. I tried unplugging the power supply for a while (my first club out of the bag of weird power problems), but no dice. Anybody have any ideas? I can't diagnose a hell of a lot with no power!

it sounds like it is kicking off because the 'sense good 5v' is kicking it off because the voltage is not holding up maybe.
if you don't have a new power supply to try maybe try taking all devices off and see if you can get it to run with nothing on it (no cd drives, no hard drives, no usb or firewire devices, no sound card etc etc.
perhaps something has a short and is dragging down the voltage. imh experience, this is not common. it is more often a failed power supply. you could vom it and see for yourself.
