I just finished building my custom PC so I turned it on and it was working completely fine (from what i could tell). It said that i could hit esc, del, or some of the f keys. I hit F1 and it showed me the specs and how it was running and some other stuff. I'm pretty sure that I need a bios update, but i wasn't sure how. I then exited the program and it didn't do anything. I then turned off the PC and turned it back on. Now it says "reboot and select proper Boot Device or insert boot media in selected boot device and press a key". I rebooted it and it says the same thing. I have tried that multiple times and its not doing anything. I also tried to unplug it and plug it back in. If anyone knows what I should do I would really appreciate the help. Thanks!
