Alright folks, I have stumper for you all.
I pretty much just finished building the setup you see below. While I still intend to do a few more upgrades in the coming months (more RAM, second graphics card for CrossFire, etc.), what you see is pretty much it for now, and it's running like a dream.
Except for one thing that has me a bit confuzzled.
If the unit is shut off for long periods (that includes shutting off the UPS to which it is connected), the next time I switch it on, the power-up sequence tends to be a little funny.
Immediately after I push the power button, the entire thing comes on. Power light comes on, the fans spin up, everything pretty much comes to life. But after a grand total of two seconds of doing all that (but before POST, I think), the entire thing powers back down, as if I never pushed the power button at all.
This sort of problem isn't new as far as I could read in the forums, but get this: After around 3 seconds of the unit powering itself back down, it turns itself ON all on its own without intervention, proceeding to POST and OS bootup like nothing happened.
So that is: Push power button, computer turns on for 2 seconds, powers down for around 3 seconds, then powers back up again to normal operation.
As noted above, it seems to only happen when the unit has been shut down and completely devoid of power for a long time (note that I turn my UPS off as well while I'm not using the rig, so pretty much no power gets into it while off). If I use the unit for a while, shut it down (including the UPS), and turn it back on again, it starts up just fine.
I have my theories, but they're just that: theories. I want to run this problem by you folks first in case someone far wiser than I knows something that I don't which might be helpful in this scenario without having to taint you with my noob theories.
And before you ask, yes, the CPU is overclocked (it normally runs at 3.6GHz, 3.8GHz on turbo, but currently runs at 4.6GHz). It IS quite stable during normal operation and I have never seen it go beyond 50-degrees Centigrade under my normal use (gaming).
Apart from the queer startup sequence, I've had absolutely no hiccups once the computer is already running.
Ideas?
