Two days back when I booted my system up, it was showing a screen with a bunch of messages and instructed to press F12 to continue booting.
Two times it showed up when I booted my system and now it is not there, the problem was solved before I could take a screenshot of the message.
The only thing important I remember of the message is "CMOS checksum bad"
What is this error and how does it occur? How did this problem fix itself?
(there wasn't any hardware changes at that time.)
If this problem persists in the future how can I go around without pressing F12 key.

Your CMOS battery is dead, put in a new one.
