W7 Ult. time is lagging a bit

[riffwraith]

Hi all. The time in my W7 seems to be lagging, about 2 min per month. I am not set to auto-sync to a time server, and I have all sleep/hibernation/etc. features disabled. I understand that the CMOS battery can sometimes be the culprit in cases such as these, but the MB/battery is only seven months old. Should I just go and swap the battery, or is there something else I should be looking into?

Thanks in advance.

Take the battery out for 10 seconds, this should Re-set the CMOS
