Computer doesn't boot up in the first try.

[The Pizza Thief]

Hey guys, I'm having some issues with my PC, everytime I turn it on, it all powers up but gets stuck in the motherboard screen, the one that says Press F2 or Delete to get into the BIOS. It stays there forever so I have to press Reset on my motherboard each time I want to use my computer. First I turn the tower on and then I have to open the side panel and press the button on my mobo because the case reset doesn't fix it. 

 

Any solutions? 

Thanks

 

Edit: Never flashed bios, motherboard is Asus Z170 Deluxe.

What Mobo? Did you flash newest bios version on there?

Try a bios update, if that doesn't help you could have a bad windows install but i seriously doubt that. If you havent tinkered around with any other settings in the bios and the rest of your parts are okay, you should be good. If not RMA the board.
Out of curiosity could you give me a partslist?
