Onda D1800 will not reboot/ shutdown and reboot

Hello, i have a Onda D1800 that i have been running with 6x vega cards for a while. i have never been able to use the restart function in hiveos because when i use it the rig dont start up again, it shuts down, gpu fans keep spinning and it dont boot. however when i turn of the power and start it again it works fine. i have noticed its a beeping sound when it boots, this dont happen when i use the software restart, any suggestions how to fix this? i have tried many different settings in the bios but dont find anything that works for this problem
