[SOLVED] B450 gaming plus won't enter Bios

[animedragon5010dez]

So I just made my pc and I pressed on and it went straight to bios, then I did everything that you had to do to download windows 10, so then I wanted to update my bios and I downloaded the update file and put the. a40 (which is the latest one at the time of this posting) in a USB. I tried to enter bios by pressing delete and it would just stay black then I tried to go to bios through the advanced restart method but it still stayed black after restart. Everything else works, the only thing that may be worrying is a light above the mb 16 pin cable there's a light, if you want further information on this just ask.
Thanks

If you meant the LED above the 24pin motherboard power connector then you need to look closer as there are 4 diagnostic LEDs there and you need to led us know which one is on and what color it is. See your motherboard manual for help in this.
