Okay, so for about the last three months or so, my computer's been doing something odd. When I shut it down, sometimes it won't power back on until an indeterminate amount of time has passed. Sometimes I can get it to cycle by unplugging the PSU's cord or toggling the switch in the back and counting to 30 or so.
The motherboard's 'power' LED stays lit even when I remove the cord, which I find *odd*.
The PSU in question is a Seasonic Platinum 1000W (not even half way through its 7 year warranty), and the motherboard is a P8Z68-V Pro/Gen 3. The computer is connected to a BR1500G battery backup with the booster pack (over 150 minutes of extra uptime under low load, and over an hour under heavy load), and because this particular UPS has crappy surge protection figures, the BR1500G itself is plugged into an Tripp-Lite ISOBAR surge protector (and only the computer and monitor is connected to it, as I don't like the idea of surge-on-surge).
It's only upon shutdown and attempted restart that this issue manifests - whenever I set the computer to restart, everything works fine. I've also gotten the computer to partially turn on during these 'episodes' by moving the plug to the second battery backup, but it's only for a second or so.
Just from my limited electronics knowledge, I'd say a capacitor (or capacitors) somewhere is/are going awry, but I figured I'd post here and see if someone else could nail down whether it's likely to be a motherboard or PSU problem.
