My new pc does not post, when I turn it on, it displays code 02 and the boot led was on. I have tried reseating ram and gpu, flashing bios, and changing boot drives.

MB- crosshair viii hero
CPU- 5950x
GPU- gtx 1080
PSU- NZXT c850
 
What bios version did you flash?

First, try a different monitor cable/port. Make sure monitor is plugged into the GPU, not motherboard. Your issue could be similar to THIS

Secondly, bread board it. Take it all apart, and run it outside of the case with just the minimum connected. One stick of ram, cpu, gpu, no ssd/hdd.

A system can post without a drive connected.

When you use the BIOS flashback it should be used when the CPU is not installed on the board. If it was redo the flashing. You put that usb key in the appropriate usb port at the rear and you press that button for 2-3 seconds until it start to flash. After a few minutes it will stop flashing. Process is done. This has to be done with no CPU in the socket installed.

After the BIOS flash you leave 1 stick of RAM, the CPU and GPU installed. That's it. Does it post?

Got it to post by formatting the ssd on another pc, but there is still q-code 02 and the boot led is on. It said that my gpu is not supported by the uefi bios.
