My pc sometimes show this sytem just recoverde from an unexpected shutdown what do i do

If you're running Windows go into Control Panel and check Event Viewer. Look under Windows, System, and look at any Warnings (Yellow triangles with exclamation marks) If you're seeing error codes you can look those up; if "unexpected shutdown" shows up a lot your laptop could be overheating or it may be a power issue.

Good chances this is a thermal shutdown. if this is the case, the computer is shutting off to protect itself from permanent damage. if your OS is old enough (Snow leopard, I think) then the system logs show what caused the shutdown. it will give a number. anything other than a 0 or a 1 are bad. if I recall correctly 1, 5, 13 are thermal shutdowns. Newer OS's don't seem to show these codes. and Apple does not publish their meanings.

Hello here is the msi homepage:

You have to be sure its the right mainboard.
Flashing the bios with a wrong one will destroy the mainboard.
It does not have to be a bios problem you have.
The problem could be a faulty power supply, or a bad ram module.
Or simply the pc is shutting down, because of overheating/overclocking.
If you get the blue sreen of death, the harddrive could be the fault.
Try also to renew the cooling paste, between the cpu and the cooling element.
Clean also for dust.
It sometime will help to upgrade the bios, when the pc is unstable.
But do fix the power shutdown problem first.
If you upgrade the bios, and the the pc is shutting down while doing this, the mainboard is scrap.

Best of luck

Once / twice OK. Real problem only if recurring.

Does it continue to work normally? Sometimes if you shut-down a computer by pushing the on/off switch instead of going to the start menu and doing a suht down the computer will see it as a crash or if you computer shuts off for no ovious reason.

If you show a Blue Screen, you have more problems then it not being able to turn off/shut down?? I would back out the battery so as to stop power from getting to it, AFTER you have it unplugged..then push battery back into to engage, plug the AC cord back into the PC. turn it back on and IF you still show a BLUE screen, you will need a tech to check it further...GOOD LUCK...

This can be caused by an improper shutdown, a download, or just a glitch in the windows operational system, In most cases it recovers without a hitch.

This is a duplicate submission -- I will be answering the other copy. Thanks.

the blue screen is known as the Blue Screen of death

Restart the PC and if the problem persist check your RAM or any new hardware installation. Sometime you may need to Restore the System to the previous state.
