Question I'm having trouble booting my PC ?

[donutwzrd]

Hi I just built a new PC and I booted it up for the first time. It took me to the American Megatrends screen.
I pressed the “del” key and it said “entering setup”. I waited for 10-12 mins and nothing happened so I searched up how to fix it and it said press “y”. So I pressed “y” and it gave me a grey screen and no keys were working. I searched up how to fix it and it said to take out my M.2 SSD and then it booted to the BIOS.

So I only get to the BIOS when I take out my M.2 SSD.
But whenever I put my M.2 SSD back in, it boots to a grey screen ?

Please help
