SLeep mode but case fans still on?

[cjsuttles90]

Recently I was playing rocket league and my PC just turn itself off or went into sleep mode. Im not really sure but the case fan stayed on and the only way i could get my PC to turn back on was to turn it off by the power supply and then turn it on by the base. Any ideas?

1| When posting a thread of troubleshooting nature, it's customary to include your full system's specs and your OS. List them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

2| Does the issue crop up when you're gaming?

3| You may also want to see if your graphics drivers are up to date. It might be that the screen went black due to a driver issue or that the system was incapacitated due to a bad or inadequate PSU.
