If you can’t access bios, that means that your motherboard is in cause. It’s even worth than a SSD issue. Contact support, i think it's your best option for now.

Are you sure you are doing it right to access the bios ? You need to give more details about how you’ve already troubleshooted your issue…

For info it’s seems some peoples are doing it wrong si here is what actually work : Hold Volume Down/Up + Power, once you hear the beep, immediately stop holding Power.
