CMOS

[bluextatic]

What would be a few reasons for using a "Clear CMOS" button that has appeared on numorous MB's or just clearing the CMOS. Why would I need to clear my CMOS? I have been computing for fifteen years and have never had to clear the CMOS.

Me, neither.

But I guess, sometimes, it is not uncommon that hardware changes and/or BIOS updates may cause data corruption in CMOS that you have to manually clear it so that it memorizes the new configuration data from scratch.

Yep! as mentioned above sometimes it may become corrupted over time.
Also comes into play when overclocking attempts are unstable.
Clear cmos returns the board to factory default settings.

Yes, there's the corruption aspect - but also if for some reason {e.g. bad OC or other bad settings} you cannot boot into the BIOS or are having Post failure then sometimes you have no other choice but to use the Clear CMOS methods.

Often 'we here' recommend Clear CMOS to kill 2 birds 1 stone: 1. reseting eliminating corruptions to the BIOS and 2. force Load Optimized/Defaults --- to 'discover' the true nature of the problem(s) {one less variables}.
