MSI MS7536 Turns itself on @ midnite

[Dub_Bee]

I recently built my daughter a new pc with this mobo. Every aspect of the system seems to be working fine except it turns itself on everynite at midnite. I have looked into the bios and have found nothing. I have also tried doing a clean os install but it still turns on at midnite. All drivers are current and up to date as well as the bios. Please help.

Try resetting the BIOS to default values.

This is all I could find as a manual, and it does not show all the
BIOS screens.

On my motherboard, I have a section in the BIOS called Advanced:ACPI_Configuration
and this setting might control the "waking at midnight".

RTC Alarm Power On [Disabled]

The hardware device being used, is described here. The real time
clock (RTC), inside the ICH7 Southbridge, has alarm registers for setting
a wakeup time. At one time, wakeup registers were controlled by a
time set in a BIOS screen. Now, Windows controls the wakeup time,
and if you use Control Panels:Scheduled Tasks, that is likely to
be the thing setting a wakeup time. If no Scheduled Task is set,
then the RTC alarm should not be enabled.

PDF page 410 - "Table 10-7. RTC (Standard) RAM Bank (LPC I/F—D31:F0)"

It could be, that a BIOS update could also fix the problem, if for example
the wake up function was being enabled by accident during the computer
boot process. But on the MSI web page for the 945GCM478 board, the BIOS
release notes make no mention of correcting such a problem.

I would start by looking in the BIOS setup screens, in the section
that controls "waking" sources, and see if there is an RTC
entry which can be disabled.
