Gigabyte Z390 Designare | Erp enabled causes PC to turn on twice

[LemonHorse]

Hello everyone,

 

I have a Gigabyte Z390 Designare motherboard and I have a problem that drives me crazy. If Erp is enabled in the BIOS and I press the power button my PC starts, the vents spin up for a second then it shuts down immediately then proceeds to start up again and the second time everything is alright and it boots into Windows 10 Pro. If Erp is disabled and I press the power button the PC always starts for the first time and boots into Windows. The only problem is if Erp is disabled my keyboard, mouse and headset stays lit after a shutdown. There are no options for the different states on this mobo. I had an Asrock Z390 itx before and it had different options for different states like S4, S5 and it never had this wierd double start up issue but I had to change it out for this Gigabyte mobo. Is there a way to fix this?

 

Thank you for your time.
