So i built my computer today and realize I lost my dvi cable in the middle of building so I continue building anyways. After Im done I did decide to turn it on and yea my post beeps when like this: one normal post beep when i plugged in my keyboard and mouse. Then reset it and tried it again without mouse and keyboard it did 2 short beeps. The whole time I did not have display since I did not have a dvi cable yet. But should I be worry about how the post beep without the keyboard and mouse plugged in?
