Sounds like the laptop needs to have its insides, and fan(s) cleaned of debris, dust, dirt, etc. If that doesn't resolve the fan issue, then the fan itself may need replacing.

NOTE: If the laptop is under warranty, then contact the manufacturer rather than open it up yourself.

but there is one more issue that when i start my laptop and type password it automatically turns off and then second time when i start it, it runs smoothly without getting turning of

That could be either hardware or software. Really depends on how often it happens, exactly when, etc. Again, if it is under warranty, then that also should be looked at by the manufacturer.
