Well it seems like that the cmos battery is down. You need to do the following

Change the CMOS battery,
Enter into bios and change the date and time properly,
Save and exit bios.

Now you should be able start your computer in windows.

Achdi,

Something has tripped the chasis intrusion on the motherboard.

This is a security device that disables the system should someone unauthorized open the case.

Unplug the power supply, open the case. Down near lower edge of the board there is a connector with several wires attached marked Panel a bit farther up from that there is one marked CHA_FAN between that is one marked CHASIS this is the connector we need to deal with. If there are wires attached to it trace them back to the module attached to the case. there should be a reset switch on this device be sure to reset it just before closing the case again. If you can not find a reset switch on it remove the wires from the connector and tuck them away (Note doing so will mean the intrusion detector will not function any longer) If there were no wires look carefully to see that nothing has shorted (connected the pins) accidentally. If so it might be advisable to blow out the case with a can of compressed air to prevent it from happening again.

OK now we need to clear the fault from the bios. There is a battery (Silver disc: watch style) on the board. Pull the battery. Now there is a 3 pin connector near the battery marked "ClearRTC" that has a jumper on pins 1&2 move it to 2&3 now wait for 15 to 20 seconds
restore the jumper to pins 1&2, replace the battery, close the case.If the intrusion detector is still functional reset it. Plug the cord back in and boot up the PC you should now be able to get into it.

You will have to go into BIOS to adjust settings again including set time and date.

If this method does not help then the error is likely internal on the motherboard, and will need to be repaired or replaced by an authorized service tech.

Hope this helps
Dave

Try to reset the BIOS to factory settings
1. Turn off the power and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper capfrom pins 1-2 (default) to pin 2-3 keep it to 5 to 10 sec. then move the cap back to 1-2.
3. Re-install the battery.
4. Plug the power cord and turn-on the computer.
5. Enter the BIOS set-up by holding the DEL key and re-enter the data.

i hope it helps!!!

    Chasis Intrusion connector (4-1 pin Chassis)



    This connector is for a chassis mounted intrusion detection or
    sensor or switch. Connect one end of the chassis intrusion sensor or
    switch cable to this connector. The chassis intrusion sensor or switch
    sends a high-level signal to this connector whenn a chassis component
    is removed or replaced. The signal is then generated as a chassis
    intrusion event.


    By default, the pin labeled 'chassis signal' and 'ground' are
    shorted with a jumper cap. Remove the jumper caps only when you intend
    to use the chassis intrusion detection hardware.

    I hope it helps!!!

Cmos checksum bad Chassis Intruded Fatal Error System Halted!


Hi,
To remove CMOS Checksum error, you have to remove the coin cell battery from the motherboard and install a fresh one. A coin-cell battery (CR2032) usually powers the real-time clock and CMOS memory. The battery is 3 Volts, 3/4" in diameter and has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery.
Just open the desktop, locate the CMOS (Coincell) and remove using screw driver. Replace the battery with CR2032 or an equivalent one.The following brands are used interchangeably for this item: Energizer (ECR2032), Duracell, Panasonic, Eveready, and 3M etc, which can be purchased from any local electronics store.
For Chasis Intrusion msg, go to the BIOS (when prompted, press the Function Key at the system startup) and locate the option of chasis intrusion option and disable it, save settings. Commonly, to enter the BIOS you have to press F2, F10 or DEL Key, depending up the make/ model of the PC you have.

Hope it helps! Good Luck! Thanks for using Fixya!

ASUS P5VD2-VM SE MOTHERBOARD


If you purchased this motherboard recently then i would double check your power supply - get a better power supply and try that - think you may need one with two 12 volt rails.

If that does not work then I would get it RMA'd as in return it and get a replacement.

Chassis Intruded, Fatal Error...System Halted


you need to go into the bios of your pc.....usually pressing the delete key when you see the first logo screen after booting up....look for a section that relates to errors and what the bios is supposed to do when it encounters an error.
i.e if you see a line in the bios that says "halt on all errors" disable it and when you next boot up the bios will not stall.
