(Sometimes) PC beeps repeatedly upon hibernating

[crsahkaz]

CPU: Ryzen 5 1600
Motherboard: Gigabyte GA-AB350-Gaming 3

RAM: SiliconPower 2x8GB 2400MHz 

PSU: FSP Hydro Gold 650W

GPU: RX 560 4GB

 

It happens sometimes (I always hibernate). I just force-shutdown it with the power button when it happens, but wondering what could be the cause.

Just started happening recently (like a week or 2, happened 2 times total so far).

 

PC has been used for more or less a year.

Upon booting up from the force-shutdown, I can still resume from my hibernate session. 

 

Any help would be appreciated.
