When it gets colder, this PC will stop before it posts - black screen, power supply fan blowing. The colder it gets, the more consistent the behavior is. If I power cycle at that point, it boots fine with no issues thereafter. I've reseated all connections & flashed the BIOS to no avail. EE was never my strong suit, but I wonder if it's a weak power supply?
In any case, I'm wondering if anyone has troubleshooting ideas (short of swapping out parts) to help me get to the bottom of it. It's more of a challenge than a crucial issue, since the system has no other problems.
