Im guessing the pc is fine. Just that you cant see image of it till the windows logo?
If so is just that initially you cant see your splash screen. Most probably its fast boot. And the fast post time. So best if you really wanna access your bios, the moment you turn on your pc, spam your bios key.
If your post is too fast. Best you can just go ahead and download an app from your board manufacturer that allows you to go back to bios when your pc booted up.
