My PC has a 7700k, 16gb corsair ram, crucial mx500 520GB, corsair h100i v2, asus strix 1080. My last motherboard was a z170 and died after 2 years. I upgraded to a 7700k on its release date. I got a new motherboard and ssd yesterday, the ASUS Tuf z270 mark 2. I put all my components together, but when I booted there was no display and an orange light in the top right corner of the motherboard. In the manual it says this means there is a system boot device problem. I’ve tried one stick of ram, no gpu, no ssd (still orange light), but still no display. Help
