Standby problem



Whenever I resume my computer from standby mode (whether by pressing mouse, keyboard, or power button), Windows (XP Pro, SP2) goes into shutdown instead of resuming normally. I'm always entering standby mode manually.

Is it possible that I simply messed something in Windows or BIOS settings, or will I have to reinstall Windows? My board is Gigabyte 965P-DS3.

Thanks,
Z.
