Clear CMOS Jumper JBAT

Remove the jumper plug from the CMOS jumper (CLEAR CMOS) pins 2 and 3. Place the jumper plug on the CMOS jumper (CLEAR CMOS) pins 1 and 2 and wait approximately five seconds. Remove the jumper plug and replace it on the CMOS jumper (CLEAR CMOS) pins 2 and 3

It is safer to remove the battery for two minutes.
If there is any residual charge in the system, and you use the jumper, you can damage the motherboard.

If you insist on using the jumper:
First unplug the power supply then push the start button to ensure the system has no charge, then change the jumper for about ten seconds.
Put the jumper back in the original position, plug the power supply back in, and you can boot he system .

Clear CMOS (JBAT)

if the computer will not boot move the jumper the 3 pins to the other side.

Here is an official link for downloading the on board VGA drivers for MSI 865GVM3-V for windows xp operating system. In case thisd is not you op. system you can use this link to choose another one. Note that Windows 7 are not supported, if this is your case you have to try the compatibility option.

The first step would be to clear the CMOS ram manually. To do this, you need physical access to the mother board.

- Make sure the power is off but do not unplug from power.

- Locate Clear CMOS (JBAT) Jumper. From above, lower right hand corner.
- Simply remove the jumper and put it back again.
- Power up.
- If problem persists:

- May be faulty ram
- If you have a video card installed, uninstall it and connect monitor to VGA port of motherboard. It could be a faulty video card.
- CPU could be over heating, clean with compressed air, check fans and CPU grease.

Hope this helps...

JBAT1 is right next to the SATA2 connector.

Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power from external battery to keep the data of system
configuration. With the CMOS RAM, the system automatically boot OS every time it is turned on. If you
use the JBAT1 (Clear CMOS Jumper) to clear data. Follow the instructions below to clear the
data:

You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position.
Avoid clearing the CMOS while the system is on; it will damage the mainboard.

Try clearing the CMOS --- the down side is your lose all your setting --- the up side is you should be
able to access your BIOS

Clear CMOS Jumper: CLR_CMOS1 ( Located near CMOS battery )
The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to
factory default when the BIOS settings were mistakenly modified.
The steps to clear CMOS data are :
1. Turn off the computer, unplug the power cord from the power outlet.
2. Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them.
This will clear CMOS data.
3. Return the setting to its original with pins 2-3 closed.
4. Plug in the power cord to your computer and turn it on.
5. Go to BIOS Setup to configure new system as described in next chapter.

• Disconnect the power cable before adjusting the jumper settings.

• Do not clear the CMOS while the system is turned on.

there are three pins on board area where the jumper is fix the jumper on the middle pin and the other unused pin and power the machine to clear cmos. rate this solution

try to locate if theres a jumper setting that says 'jbat' move it to 2-3 sttings for a while then back again to 1-2.
