There might be a couple things going on. There might be something wrong with the mobo and/ or the cr2032 battery might need replacement. Try unplugging from the wall, removing the cr2032 battery from the mobo, pushing the power button for 5 seconds, then putting it back together.  If you have a spare cr2032 battery replace it instead with a new one.  The battery might be dead. Also, have you done anything with the RAM since the pc was last restarted? Then try booting the same way.
Hello!  I’ve had this Aurora R7 for quite some time now, however this is the first real issue i’ve had with it. I was on the pc as normal the night before, turned off the power through the power button, went to bed and tried to turn it on the next day and i got no response! At first even the power test wasn’t working, however after switching out power cables only the power test works but the actual button to turn on the pc is unresponsive, the LEDS won’t even turn on, any suggestions?
Aurora R7, won't power on, test power button working
