Clearing the cmos does not just reset the default values but is more of a bios reformat which protects you against a corrupted bios. I have gotten corrupted bios many times as a result of strange crashes or the computer getting pissed over a failed boot rom. Just resetting the bios and then changing the needed settings is the fastest way to get your system booting again.

Also for those of you that may have noticed there was an issue where the new post was not accessible in that the 3rd page was not loading. This was due to a database corruption created from the issues with the server a few days ago. I have repaired all thread data and the issue should be resolved now.
