my bro didnt inserted RAM in proper way what's y it get burned
RAM is usually keyed to prevent it from being inserted (at least fully) in the wrong direction. It would have been very difficult to plug it in backward and secure it with the clips. That is of course assuming that they clips were applied.
The time and effort you will be putting into this may not be worth it. Please keep this in mind on your endeavour. Drawing enough current to cause a burn on the board or connector may have easily caused damage else-where. This damage cannot be easily found and could not show anything immediately, or could present itself as an unstable system when certain tasks are attempted.
Motherboards are multi-layer boards. There are many tracks and traces that you cannot see from the top or bottom, and you cannot trace or troubleshoot them without a great great deal of time and effort.
I am unsure where you are located, but I could buy a new motherboard for the price of buying 8 - 12GB of DDR3 memory. If you botch the repair process you may end up with a completely unresponsive motherboard. In which case the time and money going into the board is lost along with requiring a replacement.
If this is not for a custom fabricated board for some special equipment, I suggest you shop around for some prices for a replacement.
Get your hands on some old discarded computers, and for the sake of learning, get one running, then pull a ram port off and put it back in. If you are not comfortable or successful in doing this with an old discarded computer that shouldn't cost you anything, then there is no way you should touch an iron to your current machine.
I wish you luck, but there is little anyone can do on here aside from point out any other potential damage on the board when we see a picture. Of course, if additional damage is noticed it may be worth even less time to fix. We cannot reach through our screens to solder for you. This will require patients and skill on your part.
