Windows 7: Clock slowing down

Clock slowing down

The clock slows down about 20 min per day. It's fine before I upgraded to Win7 (along with BIOS update).

Any suggestion on what's the going on?

The usual cause is that the CMOS battery is dying and should be replaced. This does more than control time. When the computer is unplugged (desktop) it maintains the settings.

Isn't there a system timer setting in some BIOSes? It affects the timer interrupt somehow. I don't have it in mine, but I have seen it.

Maybe the new BIOS set it to a default that isn't using the timer properly?

Just a guess...

It's the freaky BIOS from Gigabyte. Reverted and all normal.
