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.
