Very simple, built my new computer about a week ago and rushed through the bios config. Want to get back into it to change some stuff. It's my first pc so idk what I'm really doing. Most people say just to spam 'Del' or 'F2' when the Asus logo appears, but that doesn't seem to work. My mobo is the Asus Rog Strix Z390-E Gaming in case you need that to help.
Restart your computer and spam Del as soon as you notice the hardware briefly powering down. You might be too late already waiting for the Asus logo, though that is when my Del button lets me enter BIOS.
