Keyboard won't work on new PC build and I know it and the mobo work

[C8mtron]

So I just finish building my new PC and at first everything works like it should. Then after I get windows 10 on a USB drive I turn it on and the keyboard doesn't work. The mouse will work but the keyboard got into a habit of shutting off which eventually led to it not turning on at all. I've already tried to fix the problem by using a new keyboard and I ordered a new motherboard but the problem persist. Another problem is that my monitor doesn't display the boot menu when I turn it on so I can't get into windows. When I got onto the boot menu before, I had to access bios and then save and reset. Since I can't access bios now I'm pretty much stuck. I think it could be my power supply but I'm not positive. Could someone please help me? If so thanks I advance. Here are the parts https://pcpartpicker.com/list/zzBFhq.

I apologize for missing the post where you mentioned testing all ports. I won't argue the point of reinstalling Windows out the Windows drivers. I will simply say that it won't hurt, but won't help either.

When you said the keyboard would occasionally turn itself off, did it occur randomly, or when you did something specific?

Do you remember anything else at all that occurred around the time the keyboard started cutting out?

Also, how did you get it to turn back on, it did it turn back on itself?

Lastly, have your tried a powered USB hub? If it's a freak incompatibility, that's one way to fix it. It's cosmically unlikely that this is the case, but the issue you've described is cosmically rare.

When the keyboard started to turn off it was gradual. At first it worked fine but then it started to shut off randomly on its own and eventually it wouldn't turn on at all when I powered up my computer. I have not tried a powered USB hub.

I would suggest trying something like this:

https://www.howtogeek.com/howto/linux/create-a-bootable-ubuntu-usb-flash-drive-the-easy-way/

The intent is twofold:

1) Determine if your system is still bootable.

2) Provide, by elimination, some indication that your USB drive/media tool may have a corruption problem.

Especially where two systems/motherboards have failed to work.

I've already created the tool its just without saving and resetting by exiting out of the bios screen I can't access the boot menu to download windows.

So you are unable to boot into Linux using the bootable Linux USB Flash Drive?

Well you never said that sorry ,That mother board Trashed or its windows ,If the system boots ,it can't be the RAM or The CPU it wouldn't post it would just freeze. The power supply is also out, because everything else works.A bios flash may? fix the board ,windows drivers may? fix it but its not the power supply because a keyboard pulls virtually no current aqnd everything else works ,Give it a go and if that don't work you got very unlucky with two faulty boards ,They may have tried to fix your old one and they sent it back to you they do try that on sometimes ,Good luck ,I would love you to fix andf ind out what is was and let us no because its pretty darn weird
