Is the computer not powering on...? What's the symptom?

There's not much you can do if the motherboard was electrically damaged. You would have to replace it, unfortunately.

Well the computer is not powering on

See if you can get a local tech to check the board with a multimeter to confirm voltages. From your description, though, it sounds like the charger probably tried to deliver too much power to the board and a component was damaged.

Yup, something fried, it needs professional attention.

Well to be honest i dont trust anyone in these shops. I would like to repair if needed on my own. Any suggestion what and how could i check the board?

Why don't you trust any local tech places?

Honestly, your easiest way to determine if the board is bad might be to simply replace it. You can usually connect things and boot a replacement board outside of the shell; this can save you the time and hassle of setting it all back up inside the chassis if it turns out the replacement doesn't work, either.

If you are in NYC, rossmanngroup.com is the guy, he has very interesting youtube videos on how he goes about fixing laptops.

Why i dont trust .. they charge so much and you never know what they made...i would use than the original msi service instead , but i try to buy the board as you saied first, mb its the cheapest solution

As a starting point you need to get a repair estimate from a repair tech, short of actually getting it fixed, as if it's seriously damaged it might make more sense financially to write it off & replace it. At least with an estimate you'll know where you stand. Giving it nearly 30 volts more than it's designed to withstand is bound to have done some serious damage I would have thought.
