Unfortunately it takes time to actually replicate the problem, but when I leave my computer turned off for a few hours it seems that when I come back it will not power from the case power button unless I flip the power supply switch off for a few seconds. I've not really tried picking the issue apart yet but any direction you can give me would be great. Beyond this, everything seems to be working normally.
In the event that this happens, the motherboard appears to still be receiving power, as I think the on-board power switch LED was still lit, as well as the mouse LED and the External drive LED. I'm going to shut it down before going to bed and boot it up in the morning. If the fronts switch fails again I'll try the on-board switch, if that works then I suppose I'll know that the issue is with case power switch or the motherboard's communication with it.
I left the computer shut down for approximately 3 hours (8:30PM-11:30PM) and it failed to power on either by pressing the case button or the on-board power button. I flicked the power switch on the PSU and waited until the LED on the motherboard faded. I then heard a small audible click.
I am not sure what steps to take from here. I'm sure it would help if I had a spare PSU sitting around that I could test in the rig, but I do not.
It seems like I simply cannot catch a break when it comes to working on computers.
