so ive just built my first computer and it turns on and all fans run, but when it boots i just get a black screen and a blinking dash. pressing crtl + alt + del does nothing neither does any of the F keys or any key on my keyboard infact.
if i try to boot it without the bootable usb i just get the message "Reboot and select proper boot device or insert boot media in selected boot device and press a key" but when i put the usb back in im back at the blinking dash.
unpluging the ssd didnt do anything and i cant flash the bios because i cant get into it. the usb has windows 10 64 bit and formatted in exFAT, nothing online has helped or worked.
