Question No display on Asus B85M-G

[Sentinal of Light]

So originally I was going to move my prebuilt hp motherboard into the cooler master mb311L, but I then found out that the board was too old and therefore not compatible with the case. So, when I was moving the motherboard along I removed the cpu and accidentally damaged the socket. My next move was to get the asus B85M-G as it was compatible with my i7-4790K. Now, when I installed everything into the new board and booted it the first time, I saw a bios screen that said that the USB keyboard and mouse was not connected and shut down 15 seconds later. After a few attempts it stopped showing that screen and remained on a black screen and has been doing that since. If I find out that I can upload photos I’m willing to do so, but if you have any questions about specs just ask.

Also, I don’t have an extra PSU or CPU that works with this board. Nor do I have another functioning board.
