Lian li Dynamic Razer edition

Hi all, I have a Lian li dynamic Razer case installed with a amd gigabyte B550 Vision D-P motherboard, al the bios updates have been done, everything is update til yesterday 11-01-2023. But the problem is, everytime i start a game like apex legends the case keeps disconnecting & the lights turn off. Then i hear the usb plugged in sound and its back, this keeps happening every 20seconds. Tried changing the pci to gen3 but no luck, usb are out of sleep mode's also. What should i do ?, I am using razer synaps 3. Thanks in advance.
