It's always placed on my desk beside the monitors and is linked to a UPS unit.
Consider this idea: There could be a weak or poor solder joint somewhere in the circuit for the powerswitch on the board. You mentioned it behaves differently when it's cold in the morning versus later in the day, assuming temperatures rise during the day or after use. Materials tend to expand slightly when warm and contract when cold, which might cause the connection to feel loose in the cold and tight as it warms up. You might try using a hairdryer on low heat for a few minutes to gently warm the area and test if the issue resolves. Avoid overheating the system—just remove the side cover and let the inside warm slightly to check for any changes in performance.
It might be due to static electricity. Consider disconnecting it overnight and reconnecting it in the morning.
