Need help badly for my new system build

[bluesnake100]

Hello, It's my first time building a new system and i finnally go everything put together. When i turn it on the computer runs but then it just shows up the (entering bios option text) very fast and went to blank screen. I didn't even get a chance to see what key to enter the bios. I tried del key but doesn't work. My bios is Biostar ta790gxbe. THanks

Could you elaborate; does your computer go straight to windows or does it crash/shutdown?

You can try F2, that's my backup if delete doesn't work. Or else just cycle through pushing each of the F button in order (I've been there).

I haven't install an operating system into the machine yet, just trying to reach the bios first. Thanks for your reponse
