Board needs to be powered off for hours before starting?

[Spork829]

My home server/NAS/mining machine is running an old ASUS H81 OEM board. I have this issue wherein whenever I power it off, it won't start back up. Power button does nothing at all. The only fix is to shut off the power supply and wait around at least 5 hours from when I've had the chance to test it, usually I just give it overnight. In the morning I flip the PSU back on and it starts without fail. This isn't much of an issue because I run it 24/7, so this only comes up occasionally when I shut it down to clean it out or change out a part. But it's still kind of annoying, and I want to know why it's happening; I really have no clue. What do you guys think?

Soldering problems? (Just guessing here)

It would take more than the work it's worth to pop the board out and check for cold solder joints, but maybe. Though I don't know why giving it time would be a consistent solution in that case.

Yes, He said it is old. Therefore there might be solder joint problems.

To be clear, it's not ancient. The machine it came in was used so I don't know exactly when it was new, but it came with a Haswell chip in it, so can't be older than 2013.

Something else to note is that when I boot it back up, the Windows clock is always set to the time when I shut it down, which I can fix by unchecking then re-checking the "set time automatically" option in Windows. This would seem to indicate a problem with the CMOS battery, but upon further testing, BIOS settings and such do seem to stay saved.
