My Bios clock used to fall behind. Hence I replaced the battery. But even now the problem persists. What could be the problem?

I know of people who've solved the problem disabling power management in BIOS. Strange but true.

I've also heard that Anti-Virus software can cause this in Windows, but usually when you reboot, the clock resets. The BIOS clock isn't changing, it's just that Windows "time" gets behind.

Does yours do this?

How far off are we talking about here?

On ATX boards, if the clock gets a couple of hours behind when the PC is powered off, it can be caused by bad PSU. Clock runs from +5V StandBy power from ATX power supply.
