My ASUS booting screen does not show on startup

This morning, when I was turning on my computer. (My computer is a Windows 7 64-bit, and the model is an ASUS CM5571) the ASUS logo did not appear in the beginning, however the rest of my computer turned on like normally. Whenever I usually turn on my computer, the first screen I see is this:

(Please note, this is not a photo I took, but rather found on google that is the same opening mine has)

However this morning, this logo did not appear this morning and I don't know if I should trying turning off or restarting my computer incase it was just a one time occurrence or if something's wrong. As I've said, nothing else was wrong and everything is running just fine on my computer, but this sort of bugged me and it's been one of a few quirky moments that has been happening this past months on my computer with a string of one time occurrences as well.

If anyone could off input on what I should do or what was the case of this, it would be greatly appreciated.

Boot into BIOS setup by tapping Delete, see if Quick Boot or something similar has been enabled.

Otherwise you can set BIOS to defaults after taking note of SATA controller setting and BIOS BOot order priority (you can change it to what you want, HD first is probably best).

Just wanted to update that the problem seems to have been resolved, as it turns out when I turned on my computer today, everything booted up normally. I was told by a friend that sometimes computers boot up and "forget" somethings or that it boots up slowly from time-to-time and this was (as I believe) just one of those one-time occurrences.
