Sounds to me like your CMOS battery is either failing or missing. Get a new CR2032 battery and replace your existing battery. The CMOS battery should not show any signs of bulging or leaking.

Also check to make sure that your Clear RTC RAM jumper is set to pins 1-2 (Normal position) and NOT to pins 2-3(Clear CMOS position).
