Open | Hardware Crashes blackscreen restart

I upgrade to r7 5800x3d with gpu gigabyte 9070xt 16 gb. From the first day I install those to my pc I have crashes. Black screen sound stacked and restart. Before I change psu I got WHEA 18 events from event Viewer. After I changed psu to 1200w (found it on discount) I got crashes again when I enable PBO. I don't know why and I don't know if it's only when I open pbo or not.
